The Forestry Forum

Started on my new project building a hydraulic firewood processor.

This picture shows the infeed conveyor that is 15' long the main frame is made of 3" square tubing

This shows a porttion of the splitter area still in the process of being built.  The hydraulic ram is a 5 X 24.  The splitter carriage rides on the 3" x 6" frame and uses two 3" x 3.5" solid steel
rollers to help eliminate wear on the bottom as the logs are split.

The chainsaw bar is 29", and will be powered by a hydraulic motor and eventually powered by a hydraulic cylinder.  Eventually a six way and eight way splitter will be located in the back portion and will be adjustable up and down with a hydraulic cylinder.

Still have a ways to go until its completed.

Looks like a good start. Looking forward to seeing progress pictures.

LOOKS GREAT DO YOU KNOW WHAT SIZE ENGINE YOU WILL USE ?WHAT SIZE PUMP? 

Plans are to use a 40 to 68hp engine , looking at running 25GPM pumps. 

GF

really nice looking project! building it super heavy duty as well.

Nice looking unit. Did you have plans or did you come up with a design after looking at some of the manufactured units? Tonto.

What a great project.  I look forward to more pics and technical details as you progress.  Well done.

After the mill you built, this has no choice but to be a great piece of equipment once its done. :)

Great looking project !!  Can't wait to see the progress.
I just purchased a homemade firewood processor and can see how much effort and time goes into making it operate properly. I've been tweeking some problems with mine, but overall a great unit.

Tonto,
     I didnt really have any plans, I had looked at several different ones on the internet and like ideas from different ones they I plan on incorporating.

Jeff,
    The sawmill is still going strong, the only problem I have is my full time daily office job is starting to get in the way of what I really like to do making sawdust.

Woody1,
    I would like to see some photos of the processor you purchased, and any ideas you could recommend on making the processor more effecient etc.

As I progress foward I will continue to update photos and how the progress is going.  Right now I am catching up on cutting lumber this weekend and wont get much in. 

GF,
There are a couple pictures in my gallery. There are a couple things i would like to change on mine.
1) The hydraulic chainsaw throws the sawdust out in the direction of the operator. It's no problem, but if the wind is blowing it's annoying.
2) The chain used to advance the log is #55 barn chain. There is no problem yet, but heavier would be alot better.
3) The box the cut pice falls into was too small for the wedge and pieces were getting hung up between the wedge and the box. I welded a thinner wedge on and that took care of the problem.
4) I don't have a live deck....soon to come.
5) There is not a solid brace under the dog. I am going to weld a piece of 2x2 box under the carrige.

If you have any questions at all..just ask .

I was needing some information prior to building the six way splitter if anyone can help.   On the center vertical section of the six way splitter how much further out does it extend before the rest of the six way splitter wedges make contact with the log?  Thanks

GF

Ran across this,   http://www.youtube.com/watch?v=nZq9OLLA0tI

I wonder how large diameter it can handle? The conveyor is a hoot, maybe a little too enthusiastic.

Clever concept. Chops and splits all in one rotation of the rotating knife.
There are several videos connected with this, but only one shows a larger diameter about 12", and likely spruce.

That is a clever concept but how long could the belt on the infeed put up with that abuse?

GF,

Looking at your processor.  It appears you have a very good start on it.   I am considering building something similar and am looking for an idea for an oiler.  How are you planning to oil the chain ?   Local equipment dealer suggested something simple like a gravity feed bottle with tubing.  Set the bottle up with saw so that when the saw is vertical, no flow.  When the bar goes down, the bottle inverts and gravity does it's thing...  Had a similar set up to oil chains on a round baler.  Seemed to work O.K.

Also,  did you ever settle on hw to control the saw chain, the saw bar and the clamp from one valve ?

All help appreciated. 

Warren

Hi Warren

I know you were askin GF but I give you my 2 cents any way (free of charge).

I tried a gravity feed on my CSM because I used a B&S engine from a lawn tractor instead of a chainsaw, it didn't work, may be I could have tried larger tubing to get more flow but I found if I thined out the oil and it was not too cold out it almost did oil enough but the next time I would try it, it was colder and did not work good at all.

What I ended up doing was adding a large electric bellows fuel pump to it (the low pressure kind that make the clicking sound when running) at the hole where it goes to the bar & chain I put a small ball valve to turn off when not in use and a needle type shutoff to adjust flow rate, I my case I wired the pump to the same switch as the drive clutch so it only oils when the clutch is on.

Another idea I had was to add a small 12v air compressor to pressure the tank and a electric valve wired to  the clutch switch.
For a firewood processor the switch or a valve (electric or not) could be controlled by the movement of the cutting bar.

Hopefully some one who knows how the real ones work will chime in and let us know, I am enjoying watching this thread and waiting for the next installment.

Cheers

Hilltop,

For my situation, air will not be an issue.  However, the electric diesel diaphram pump would be relatively simple and cheap ( $40).  Pardon the thinking out loud...

Set the bottle up in a gravity feed situation.  Use a normally closed plunger switch.  like off of a car or truck door post for cab lighting.  When the saw bar is all the way up, the switch is pressed, the pump is off.  AS soon as the saw bar starts down, switch closes, pump starts.   At top of cycle again, switch is pressed, pump shuts off...

Could be workable...  Thanks for the idea...

-w-

On my processor the bar is oiled via the hydraulic line going to the saw motor. There is a small drip valve teed into the line. It works fine and dosn't use much hydraulic fluid at all. I was worried about using the fluid for bar lube, but the old guy that built, has used it for years with no problem. If you would like a picture of the setup..let me know.
Woody

I think I get it , I had thought I had heard of that before but wasn't sure enough to say it out loud.

As for myself I wouldn't mind seeing it if you get the time.

Cheers

I know exactly what you mean.  ;) But it's easier to say it when you can prove it works ;) ;). I will go and get a picture tommorrow and post it, if I can. If not it will be in my gallery.
Regards,
Firewoody  :D :D

Plans are to use a small 12v pump probably a electric fuel pump of some type, I will them install a small switch where the bar is located, as the bar is lowered the pump will kick in and start oiling.  Hopefully this plan will work.  Thoguht about gravity but on cold days was not sure how well it would actually work.

GF

I went and took a couple picture of the bar oiler. The silver adjuster in the center of the picture is drip adjuster. The fast the chain spins the more oil.

Great stuff Woody. Thanks

Looks like a well made rig!

It looks like the hydro motor, saw bar cylinder and oiler all run off the same curcuit, Does it have a way to control the speed of the cylinder?  I was wondering if the bar moved too fast the chain would stall? Also wondering if it is all on the same valve there must be a one way check valve after the cylinder tee so the saw chain won't run backwords when returning the saw to rest position?

Sorry for all the questions, I have been thinking of making a processor although on a much smaller scale than yours and thanks again.

Cheers

I like what you have done so far. I bought a Timberwolf Pro-MP almost 2 years ago and the thing that sold me most on it was the clamp/roller for advancing the log for the next cut. I have put some real crooked logs down through it. If you could design something like it, I think it would be well worth the time and effort.

Timberwolf uses an electric pump for the bar oil. It is activated when I pull the lever to engage the chain that is driven by a hydraulic motor. One lever for the chain one lever for the bar.

Hope this helps.

Happy Trails

I am working on machining and building the six way splitter and had a question hopefully someone can answer.  The vertical section of the splitter I made from 1" thick solid steel, I was wondering on the other horizontal section if they also need to be 1" or 3/4 inch?   I have never seen a six way splitter but some look as if they are made from 3/4".    Any help is greatly appreciated.

Gary

GF
Just wondering if your making any headway on the processor ?

I have made some progress, have the clamp built and in place and the splitter mechanism, and trough built and in place.  I have machined the large upright splitter wedge, and still lack machining the shorter ones, once I get them done I am going to but a hard surface edge on the front and machine it down.  Hopefully I can get some updated pictures up this week of the progress.

GF

There's a lot of work that goes into a project like this one.
Keep it up. You'll have a great setup when you're done.

Mine's just a little rig next to yours. :o

archertwo
Do you have a video of that rig operating?

beenthere, No I don't. Sorry.

I'd love to put a video of my processor running on the forum. My daughter has a video camera, but I don't have a clue where to start..as far as downloading on to a web site.
If I get the video..can I get some help ?

Regards,
Dumwoody.  :D

I'll try, I would love to see it running.

I should be able to help you get a video up and running but I have never done so. I imagine that you put it at youtube and then post a link. If I can do it, I'll list the steps. Meantime, if anybody can help, please feel free.

Step #1. Become infuriated while trying to remember your user name and password at youtube. I hate those squiggly letters that you are supposed to be able to read.  :-\ 


Now I find that none of that is needed. While fighting against google, my son made a video with his telephone! He put it up with the title "Google hates my father" but we still didn't figure out how it's embedded here. Tom? Jeff? Come on in boys!

Den,
Go to the video on youtube and on the right hand side is a box with both the URL and the Embed code.
You can simply highlight and copy the URL and then paste it into your post like I just did. Some videos you need to use part of the embed code if the URL doesn't work, but try the URL first.

Jason


Thank you Jason.

zzYep, all you need for a youtube video to appear in your post, it to get the url (web address) of the youtube video, and post it. You dont need any other code, the forum produces that when it recognizes the youtube link.

Today I got around to taking a few updated photos, did not make alot of progress this past week been in the house where its been warm fighting off a cold.

This is a photo of the six way splitter, finished machining the edges this week and got it welded up.

So far the entire length is 18', its been an interesting project to build as I sometime wonder why I keep wanting to build my own equipment.

I would like to see any videos others may have of fire wood processors they have built.

GF

GF

WOW !! Lookin' great. You sure do nice work. The splitter looks real nice..It should pop those blocks.
I can't wait to see more.
Woody

GF that looks great and you are very modest.  For those that don't know.  GF built the red mill in the little picture under his handle.   

GF,  I suppose it will be painted red to match the mill?

Not sure what color it will be yet, still working on the hydraulic configuration.  The processor will have several different circuits so this will be something new I will have to learn over a sinlge circuit that the sawmill has. 

GF

Gday

GF your doing an excellent job on the Processor and if the Bandmill is anything to go by itll look and runn alot better than alot of things you could go out and buy Mate  ;) ;D ;D 8) 8) 8) 8)


its been an interesting project to build as I sometime wonder why I keep wanting to build my own equipment.
GF


GF I,ll give you a quote from Australian Forest Industries Journal January Issue 1980

The Timber Industry seems to spawn men with natural ability and initiative, and is probably one of the last industries to permit men to "Do their own thing" with efficiency and effectiveness!.

And there is alot of people on this forum who fit that bill Mate  ;) ;D ;D 8) 8) 8) 8)

That quote was the end of an artical on the Corbet bro,s of gympie qld who at around 30 yo had built a decent size logging and milling business from scratch with their production mill built from rebuilt and corbet modifyed gear to suit their needs eg a tie mill that coud cut about 2millionbft + of ties/sleepers per month out of equipment that had been scraped by other sawmills  ;)  I know one of the brothers personaly and Al has afew mills now including one in Wa that has a a log intake of 43million bft pa  ;)

Just reading your thread and the line in your last post made me think of that artical and i got it of the shelf and thought id share that quote with you all as i think most of us sometimes wonder why Mate  ??? :) Just rmember its the end result that counts even if we have to spend alittle time tweeking thing to get it just rite  ;) ;D ;D ;D 8) 8) 8)

I allways like the idea of buying a new mill but always keep coming back to building my own the way i want to work  ;)

Regards Chris

Chris,
I guess one thing about making your own equipment is you don't have to worry about buying replacement parts the manufacturer proprietarily builds for their own equipment.  I also like the idea of it being paid for when its complete and not having to owe anyone.

Doing office work all day I guess does not seem very rewarding, after a full week of office work you cannot see any accomplishment, after a single day of building a project outside of the office you can see some rewarding accomplishments.

I have 6 years left at my office job before I can retire, unless something drastic happens I plan on hitting the door the first day I am eligible

GF, I reread all your posts and didn't see mention (could have missed it though) of what hydraulic motor you were using to run your saw.
I've been thinking of going hydraulic on my processor but can't seem to find much info on the motors used and what they take for gpm, rpm, etc.

The hydraulic motor I am first going to try to use is a Parker model MGG20030, it runs at 5,000 RPM.

According to the calculation of "Hydraulic motor power (Hp) = Torque 166(in-lb) x 5000(RPM) / 63025" the motor should produce around 13.1hp at 1500 PSI at 100% efficiency or 8.5hp at 1500 PSI at 65% efficiency. 

The other calculation I used was pressure (1500)PSI X 15(GPM) / 1714 which also shows 13.1hp

The motor is rated for 2000PSI intermittent and 222in-lb intermittent, with this calculation it shows around 17.5hp at 100% efficiency or 11.4hp at 65% efficiency.

If this does not produce enough torque I will then regroup.

It was hard to find a hydraulic motor that might even work for this, then again I'm not sure of what I am actually doing so its trial and error. 

I ended machining an adapter for the hydraulic motor to accept a normal 25mm harvestor sprocket.

Gary

Thanks Gary.

Rick

GF,

What pitch/gauge chain and bar are you using for cut off ?  Also, how many teeth on the harvester sprocket ?

Thx,  Warren

GF I was looking at a processor on the net the other day and it gave the following info on one of their's

It has a 41.6 hp diesel.

Hydraulic Pump -3 sections:
1st Section @ 28GPM - Saw
2nd Section @ 28GPM - Splitter
3rd Section @ 10GPM - Conveyor

It gives an idea of what kind of flow it uses to run the saw it also says the saw runs at 6500rpm, May be you can work the numbers backwords to your specks to get some ideas, I would think that to error on the lower chain speed side would be better than over loading the system and engine to try and get a little more chain speed but not having any power.

The chain is a 404 chain with 99 drive links, the bar is a WoodlandPro 90cm (bar that is used on a BlockBuster 20-22 and 22-22, Baileys item number WPT 90 SM80).  The sprocket is a 11 tooth 25mm bore sprocket (Baileys item number # HS404 C11)

Would be interesting to see what brand of sectional pumps they use, so far I have found only that Prince hydraulics will let me put together a sectional that I would need to a certain degree.  Would be nice to get a setup with the 3 sections you described. One thought I am working on is a two section pump, section one running at 25GPM and the second section running at 20-25 gallon per minute then using an adjustable flow divider on the second section to break it into two circuits.  The concern I have with the flow divider is I am not sure how much fluctuation will occur between both when they used and not used in sync.  I have not done anything with multiple circuits and ideas and input are appreciated.

Gary

It is here where I had seen it, there are pictures, viedo and more specs as well.

http://www.bellsmachining.com/index.php/firewood-processors/4100-series-firewood-processor

I don't know much about multi circuits, I have seen pumps put side by side but am not sure how they were driven (gear box, chain, or belt etc.) My thought about that is you could use a two stage pump for the splitter to reduce splitter cycling time or it may be there are two stage available for multi sectional pumps as well.

Another option would be to put one pump on either end of the engine?

Nice looking work you have done.

Gday

Ralph V from CMS on the left side of the screen is the dealer for Bell it might pay to drop him a line he might be able to help out with hyd parts aswell Mate  ;)

as for the colour i like monza red i seem to paint everything that colour or black  ??? :) ;) :D :D ;D

Gary,  Thanks for the info on your chain set up. 

Commercial Shearing makes multi section pumps.  Used on a lot of industrial equipment. ("C" inside a square).   A couple are listed on CL right now with 1.25" - 14 spline input shafts.  You can go to the Commercial website and down load a manual that will let you decode the model number into size, ports, mounts, rotation, etc.  I would already be on these except I need a 7/8" 13 spline tandem pump to fit a Chelsea pto.

-w-

Gary,
Great lookin job on the processor. I also built my own sawmill (Linn Lumber Mill) Manual but it does what I wanted it to do. I just found this thread and read it and thought i would comment on the chain oiler. Have you considered a plunger pump that is pressed every time the saw bar comes down? I have been a water well driller for 30 years and have always found that the less electrical there is on any piece of equipment, the less downtime you will have. This is just my opinion.

Toby

junkhound,
      I am still in the thinking process of the chain oiler  ::), I need to look into your idea of a plunger pump.  I like to stay away from electrical also as much as possible.

Gary

I did get the back mount for the splitter ram all built and mounted from 1 1/2" thick steel.  Also on the front of the log pusher I cut a piece of tread plate steel to fit and drilled several holes and welded the outside edge and welded the holes hopefully this will keep the log from slipping under pressure.

I did get some hydraulic fittings and hooked to my other log splitter pump to test.  It split a 18" oak and knotted ERC log with not effort considering the pump is a 18GPM two stage.  The real test was removing the splitter and using a piece of steel between the log push plate and the the 8" steel where the 6 way rest against.  The purpose was to put the steel on the top portion first and apply 30-35 tons of pressure to see what moved or bent while under this amount of pressure, the same was done at the bottom portion. 

The goal is to either split a log, and if it cannot then to stall the hydraulics, anything in between would not be acceptable, dont want to have to think about what may bend or break if you get a knotted log that maybe difficult to split.  During the test nothing bent or broke but I seen some torque going on in areas that I want to go back into and add more steel to.

Gary

Finally found a site with decent information on hydraulic motor requirements, hp, chain speed, etc for harvestor bars and chains.  Also has recommendations on flow rate for oiling chain.  (high !)

http://www.madsens1.com/default.htm

-w-

Can someone help me, I am trying to see what the maximum GPM of hydraulic fluid you can get through a 1/2" hydraulic hose?   I see some valves the have 1/2" work ports with 25GPM flow rates, for some reason I was thing around 20GPM was the max using 1/2".  Any information is greatly appreciated.

Gary

15Feet per second is the JIC maximum flow rate recomended.
You will need 1" hose and ports to make it happen.

Not a very straight line but it crosses down from 25 GPM to 15FPS intersects at about 1"

(https://forestryforum.com/gallery/albums/userpics/16699/fc.jpg)

Jim

GF,

Nice Project!

-a couple of questions, why do you need the sectional pump arrangement?  Will there be multiple hydraulic functions trying to work at the same time?

The 25 gpm through the 1 inch hose was answered correctly according to the velocity chart.  This is for runs of line, etc. A 1/2" fitting at the end will create noise, squeal, and make heat.

Joe

Joe,
    It will be running multiple hydraulics at the same time, while the splitter is cycling it will also be advancing the next log, clamping, and cutting to length.

Gary

GF You need a copy of the designers manual put out by Womack Machine Supply Co. They have an office in OKC. It has all kinds of engineering data dealing with hydraulics and pneumatics. They have given me two copies over the years. Keep up the good work. Stan.

I guess I need to get a manual, what keeps throwing me off is looking at hydraulic components such as checks valves, etc that are 1/2" with 30GPM flow rates as the specs.

Gary

GF,

Here are a couple links to tables I found on the internet re: hydraulic flow rates and sizing:

1) Good info on hydraulic hose/tube sizing for both pressure and suction lines:
http://www.cylinderservices.net/store.asp?pid=10726&catid=19717

2) Good info on hydraulic motor/pump calculations: 
http://www.madsens1.com/harv%20pumpmotor2.htm


3) Oregon's page for Harvester components.  There are 2 or 3 pdf download files on this page that go into a lot of detail.  Takes some time to pick thru them.  But good info on sprocket diameter, chain fpm minimum, optimum, and maximum, expected cut rates, etc...
http://www.oregonchain.com/harvester/harvester.htm


What is the displacement of your hydraulic motor ???   I am thinking I need something in the 1.2 to 1.5 cubic inch range to get 4000 to 5000 rpm at 25 to 30 gpm with reasonable torque at 2500 psi...

From what I can find on the net, 3/4" hose is borderline at 30 gpm.  Prince RD5000 over the counter valves are rated at 25 gpm.  Brand has over the counter valves single spool to 45 gpm. 

I am planning to run two sinle stage pto powered pumps at approx 30 gpm.  One circuit for splitter functions.  One circuit for saw functions.  Will run 1" pressure hose from each pump to first valve body.  Prince has an "auto cycle" two spool valve that will fully extend, and then fully retract the splitting cylinder with only one hand movement at the beginning of the cycle.  I am planning to use this as the first valve body on the splitter circuit.  It can be ordered with 1" inlet/outlet.  But max 3/4" on the work ports.  Second valve body coming off power beyond circuit will be two spool for tipper pan and wedge up/down.

On the saw circuit will place a splitter (priority ?) valve ahead of the saw control.  Major flow to the saw motor. Minor flow to the saw up/down cylinder.  Power beyond from the saw motor will feed the log grapple and infeed cylinders.  Even tho Oregon says "no", I really like the idea of bleeding hydraulic fluid off the saw motor circuit thru a needle valve to lube the bar and chain.  No electric circuits, or other contraptions to fail or screw up.  When the saw is running, lube is flowing to the bar and chain.  When the saw is off, the lube is off.

I have most of the hose rounded up.  Hopefully hydraulic pumps will be enroute next week.  Still trying to locate PTO's for a Fuller / Eaton FS5306A transmission aka "Brazilian 5 speed" at less than dealer new prices.  (chelsea models 236 or 442)...

Hey everyone,i'm new here.Looks like a really great forum!!Just wondering if you could tell me what you think this project is going to end up costing,Not including your time.I'm looking into building what would basically be half of what your building.I want to make just the log conveyor with the saw to cut the logs into blocks,but without the splitter.

tree98,  I can't help you with your question, but I can say....Welcome to The Forestry Forum..... :)  Glad to have you on board.  Tell us a little about yourself.

Thanks for the welcome magicman,I'm 31 yrs. old live in northeast ohio.I own a tree service and have worked in the tree industry for 13 years.I've always liked sawmills and wood processing equipment.I'm really glad i found this forum!!

Welcome to the forum tree98, I hav enot figured the cost I have in the processor as of yet.   As i buy itmes I just put the receipts in an envelope for that project and will add it up at the end.  My goal is to make a high production firewood processor with all new components including the engine for under $10,000 (this includes my free labor  :D).  We have had some cold weather lately so I have just been hibernating around the wood stove in the house, hopefully this weekend I can get back to working on it.

Gary

Very cool GF!! I figured about $10,000.I've been having trouble finding the right chain for the log conveyor.Where did you get yours?

Hi guys I'm also a new guy to the forum. I've been sitting back and reading all the different threads. I am also planning on building a wood processor in the spring with my father-in-law. I've been watching the progress of GF's wood processor and it's a great job. Can't wait to see it up and working. I'm looking for any feed back on the CRD wood processor.

I live in northern Saskatchewan, Canada. I live within the forest fringe of the Porcupine Forest. We burn wood for our main source of heat, so a processor would make work a whole lot easier. I found this forum when looking for firewood processors and am finding this very informing.

Gorshi, welcome to the forum.  8)

You are doing a great job GF and really enjoying this thread.I just put a hydraulic cut off saw on my home built processor.Got it from from Danzco Inc. (www.danzcoinc.com) they have a good web site that you could get some ideas from.

Hey teaW,thats an awesome site.Looks like those guys already have it figured out for us!!Just curious what a saw from them costs?

tree98
the saw that I got is for 20gpm and it cost $2900. They make them for 14 to 30 gpm , to suit the capacity of your pump. I got mine with a 25 " bar. The oiler for the bar works well but it is a fine adjustment between enough and to much. The oil tank allows you to use whatever bar oil you want as there are alot of different ideas on that here.
TeaW

Any new pics?Also does anyone know where I can get the chain that moves the log to the saw?

I currently do not have any updated photos, I am in the process of building the trailer, and getting ready to start on the bi-fold 12' live deck once the trailer frame is completed.

tree98,
      You can purchase the conveyor chain from www.baileynet.com search for chain on their website and it locate it for you.

GF

I am new here.  I am bilding a wood processor and have a few questions.   I am planing on using a old 2 cylender wesconson 3 1/4 x 3 1/4.  every thing I fine about this engin is that it should produce 18 horse and 3600 rpm.  For a pump I was going to use a 28 gpm to run the whole works. the spliting cylender is a 7"x 30" catiplar cyl off a tracked loader. is this going to work all right or should I use 2 pumps one for the spliter and one for the rest if so what pumps would be best?

ddwilsonjr,
        The minimum horsepower from what I have found to run a two stage 28GPM is 16HP, the 18HP should be enough to run the pump.  The 7" X 30" cylinder will have alot of splitting force.  The next question will be what size ports the cylinder on it has, if its 1/2" port the maximum GPM through a 1/2" hydraulic pipe I believe is around 21GPM, you you use 1/2" hydraulic hose its drops to around 18GPM.   The port size on the cyclinder is going to also determine the hydraulic volume.

The question on should I run two pumps will be answered if you are planning on running two hydraulic components at the same time, such as the log splitting while cutting another log to length with a hydraulic saw at the same time.  Also I think if you try to run a hydraulic saw with a two stage pump you will find out that when it exceeds the 650PSI of the first stage while cutting a log to length it will kick into the second stage which will be about 7GPM (25% of 28GPM) and then you will notice a major slowdown on chainspeed.   My plan is to run a single stage 20GPM pump strictly for the chainsaw chain hydraulic motor.

I am by no means a hydraulic expert but a trial and error type, hopefully some other expertise on this forum can also give some helpful input.

Are you just using roller chain,like big bicycle chain?I was thinking of using something a lot wider.

ddwilsonjr
That 7 by 30 cylinder will take about 20 seconds to cycle .That's along time when you are standing there waiting.

tree98,
     I will be using conveyor chain to move the logs.

thank you every one for the help.  the cylender has 3/4" hose ends I was planing on using a 3/4 in and 3/4 work valve.  I under stand what you mean about when the two stage kicks down in to low it it would not give the saw enulf fluid to oprate it efently. it will be know problem using a secont pump.  we have large elm, ash, and cotten wood trees here and I want to beable to split anything i stick init.  I will keep reading what every one has to say and ask questions as needed.  thank you.

DD:  The force you generate can be friend or foe. A 7 inch cylinder will generate 38.45 pounds of force for every pound of hydraulic pressure. It will take a substantial frame and good welding to cage that monster at 2000 p.s.i. That cylinder could use a substantially larger pump, but that calls for horsepower. You could end up with a bigger pile of split wood with a smaller faster cylinder and have a bonfire now and then for those too knarly to split, but the cylinder you have will bust them ALL. I think two pumps will be essential.  Stan

 I am looking for some input on the live deck for the logs.  The live deck will consist of 3 strands, the live deck will fold in the middle and will fold out to 12'. I am trying to figure out how to incorporate a hydraulic cylinder to do the folding in the center section of the live deck when the deck is folded there is a 2" space between both pieces, this will more than likely require the cylinder to be mounted to the sides. The 8" X 12" square steel in the center is a 1/2" plate welded to the 5' section on each side.   The tubing is
2" X 6" X 3/16" Below is a rough drawing of what I have built.  Any engineering ideas are greatly appreciated.

GF,   

To work out the linkage to fold the unit in the manner shown in the picture, it might be beneficial to look at a large set of disc harrows.   They do the same thing with disc harrows in the 30 to 60 ft range to make them fold for transport going down the road.  IF there are any large grain or crop farms in the neighborhood, might be worth a little time to see how their discs fold up for transport...

-w-

Is this pinned to the wood processor on the left side of drawing?

Wondering if it would be eaiser to put a cylinder on the side of the processor pushing the first section up and letting the outer section pivot down on the end (would make a ^ shape when part way up) if equiped with a way to hold the outer section out until open it would unfold with only one set of cylinders and when open will not open any more. Kind of like what you have drawn only upside down. Not sure if this makes any sense to you at all.

Hilltop366,
       Yes the left is pinned to the processor and will lift up by a 24" stroke ram.  I thought of doing what you said about the unfold, but it will need a cylinder to extend the section out.  The left side and the right side in the drawing will have all three strands of each of the left section attached together and the three strands of the right section will be connected to gether, this will allow each section of the three strands to use a single ram.  Thanks for all the input and ideas.

Gary

Ok I think I get it now GF, It must be the cold weather making my brain slow.

Perhaps it could take a cyl with a rod with a cross drilled hole in it and a plate on both sides on the outer section so when it folds up the rod will go in between the side plates in order to have enough travel. The 2" doesn't leave a lot of room to work with.

Also wondering if a linkage could be set up so the outer section of the deck is unfolded by the action of the first section being lowered kind of a 3 hole triangular plate where one point is the pivot another the rod to the processor frame and the last to the outer frame. It maybe kind of a trick to get the lengths and travel distance just right.

Just kind of thinking out loud.
Guess I'm going to have to do some more thinking.

Wondering what you have planned for the chain, will it be a single loop for each strand or will it be a loop for each section , kind of wondering if it was one loop per strand if there would be issues when folding the deck.

I modified the drawing to show at what I am actually trying to do a little better (hopefully).

Hilltop366,

That maybe an idea, I have not thought of that and will put more thought into that, that very possibly could work.

Below is the updated drawing, when the live deck is folded it does not need to be evenly folded like the first drawing.  Each strand will have a single chain loop, it will pass under the live deck side so when mounting the cylinder on the underside this has to be taken into consideration.  I am still working on possibly trying to figure out out to route in on the inside of the live deck for the bottom side.   The problem is when the deck folds the chain will need to increase in length (around 14") do to the center pivot point on the live deck.  Any ideas are appreciated.

(https://forestryforum.com/gallery/albums/userpics/11029/Drawing%7E0.jpg)

As the deck folds up the chain needs to get longer on the top but shorter on the bottom, could put a bungee cord under the lower chainon each strand to hold up the chain when folding.

I get the idea its too late but a idea I had in mind was to make a deck with two chains per strand having the two beams per strand over lap each other with a shaft going through all of them with two sprockets per strand on the pivot point to provide power to the outer strand.

GH and others...
I am new to the forum. Wish I had found this sooner when I started on my processor!
You are further along on yours than I am on mine.

It may be too late for you to incorporate, but what I thought about doing for the live deck was to use an OD tube on the outer section that could be slid out and pinned. When the time comes to move, pull the pins, slide the deck in and raise the section. When the live deck is up and locked...just let the excess chain pile up in/over the log tray.

From looking at your drawing...where are your outer support legs going to go and how will they attach? Which way will they fold for transport?

Griz, welcome forestry forum.  This is a great place.

Thanks Fishpharmer.

It has been great following GH through the process of building his processor. Great ideas have been shared. I hope GH and others will still contribute...We'd love to see his finsihed product..he sure does nice clean work.

Have not worked on the processor for the past week or so, had alot of other things to catch up on.  I did start to order some of the hydraulic spool valves etc.  Hopefully I can get some updated pictures uploaded before long. 

GF

blackfoot griz,  Welcome to The Forestry Forum.  Yes, there are many good ideas and very knowledgeable forum members here. 

Griz  Hi and welcome there are lots of good ideas and home built things on here with really nice people willing to take the time to share, I enjoy the home built stuff a lot when I do have time I find I get lots of personal satisfaction from making things. I would like to hear more about your processor (pics are nice too) design and layout.

Cheers
Hilltop

Thanks Hilltop!
Unfortunately, I haven't had much time to work on my processor lately. I'm starting to sort my way through all the possible combinations of engines, pumps, cylinders, motors, sprockets, bar oil options, chains...it can get a little overwhelming!

I'm still iffy on:
1) On the splitting cylinder...4 or 5 inch? 4 is faster, 5 has more umph...leaning toward a 4 inch. In Montana its pine, fir or larch-I won't have to contend with elm, oak, hickory etc.

2) Gas or diesel engine? I've changed my mind too many times on this!
3) Chain saw or slasher/circular blade...

Just walked past my project in the garage....it's become a catch all.

I will try to get some photos posted in the near future.

I love this thread!  I love it so much I had to register to the site.  I have been wanting to build somthing like this for a long time.  It's cool to see somone actually doing it.  Since I'm such a simple man I thought of somthing simple that I would maybe try for a chain oiler.  How bout a grease gun for a pump.  Attach some kind of a tank to the barrel of the gun and attach the lever to the to the saw bar actuator in such a way to give it a squirt every time the bar is actuated.  If that supplies too much oil a needle valve can be installed in the discharge of the grease gun.  This may sound too simple but that is somthing I think I would try as I have used grease guns to pump oil before and they work great.  I have even used a grease gun to pump antifreeze into frozen bulldozer arms (manually adjustable threaded) so that they could be adjusted in -40 degree weather.

Again - I'm impressed with the things you guys do!

Welcome to the Forestry Forum.

Stonebroke

AvT,  Glad to have you on board.....Welcome to The Forestry Forum..... 8)

Thanks guys I hope this thread hasn't died.. sorry for my delay in replying.  I still have trouble navigating this site but I have been trying to find info on bandsawmills.  I am seriously considering buying somthing like a TimberKing B2000 or Woodmizer Lt 40 and a firewood processor as well.  My day job is getting to me and I have to find somthing more satisfying and consider retiring and starting somthing else.  Can any of you guys direct me to a good thread that compares these two sawmills?

Thanks in advance

GF......Do you have any pics of your wedge set  up? I am looking for some ideas on building one similar. What Kind of steel did you use for the wedge? Is it colled rolled?

Was wondering how the processor was coming, any updated photos, one idea for the oiler is to use gravity feed out of the tubes in the mainframe and to run the hydraulic lines along the side to warm up the chain oil so it flows better, one guy I talked with used the idea and said it worked great just use thinner oil in the winter.    I believe CTI uses this approach to oiling their chain and it worked great, so does built rite and I've talked to people that run them and they liked the idea.    Hows the splitter working?    Most of them I've seen stager the wedges so it takes less power to push the block through, it splits it in stages instead of all at once.   Any progress on the hydraulics, valves and motors?   If you go to 3/4 pitch chain you can run it about half as fast as 404 and it makes the motor possibilities a lot easier due to the slower speed and you also have more torque.   

I hadnt worked on the processor for the past several months, been busy trying to keep up with logs coming in to cut for lumber and keeping the grass cut on the farm.  I am guessing it will be fall before I can get back to working on it.  If I do have a little time on the weekend I seem to end up hooking on to the boat and going fishing just to get away.

GF

I've also been busy this summer building a wood processor. I've been using material from various sources, mostly old farm equipment so the cost hasn't been to bad. It has been a big learning curve and alot of trial and error, more errors than trials. I hope to post pics shortly. It does work good though and plan on bucking up a pile of wood this weekend. I've got plans in the making for another one this winter, just a little different- a gillateen. I will let you know how that's going. Does anyone know of a dealer that sells large buzz saw blade- 48"?

Welcome to the forum  gorshi.  I see that you are not too far from me.  I think I need to build myself a processor too but for now I have too many projects in the fire.   What are you cutting for firewood? spruce? 

No, I'm cutting popular. I've got approx. 75 cords skidded up since last year, started cutting up today. The processor is working fine but the cycle time is to slow. Have to change pumps. Always a work in progress, changing a little of this and a little of that. Hydraulic pumps is the biggest problem, gonna have to pay some $ for some different ones.

I recently got a little processor.  It is not a super high power outfit but it has a really fast cycle time due to its two speed action.  When the going gets tough the ram goes into low speed high pressure mode then back to high speed low presssure as soon as the wood is split.  If you can figure out a way to do that its the way to go.

I guess I'll have to invest in a 2 stage pump. Any suggestions on which kind to buy? GF are getting any closer to getting yours done?

Large 2 stage pumps are expensive. Just add another pump like you already have. Plumb them in parallel. Might be wise to put a check valve on the outputs. Woodmizer super bandmills have just such a setup.

Well uhhhhhhhhhhhhh, its been a busy spring, summer, and fall.  Now that winter is around the corner I plan on getting back on it and completing it.  I've been busy mowing grass and cutting logs when I have the time.  I am backed up about 6 sawmilling jobs right now, and finally hope I can get caught up.  I have most of the parts I need including bearings, conveyor chain etc. 

Gary

  Well winter is here. >:( We have 3-4 inches of the white stuff. I ordered a 2 stage pump, 28 GPM, from the states for 1/2 of the price here. 8) Should be here in a week and 1/2. Can't wait until gets here and put it on but until then..... I will keep on slugging, and watch the storm from inside where it is warm.

Well atleast you are putting some time in cutting wood there gorshi.  If ya can get the kinks out and run out of wood I got lots of spruce that could be done.  ;)  We got about 8-10 inches of the white stuff here already and it's still coming down.  Do you saw lumber too? Or just firewood?

What's all this talk about snow? You guys are sending chills up and down my spine. I'm beginning to think that summer is almost gone.  ::)

Ya we got about 10 inches of that wet white crap yesterday plus a pile of wind yesterday and today.  Temps are dropping to about -14 Celcius tonight and then gradually warming through the weekend with a daytime high of 12 Celcius by tues. ::)

I just put on my woolies.  :D  :D

No, I just do firewood. Bandsaw in the future, but a larger wood processor is first on the agenda. Back to cutting wood tomorrow, storm over...now back to work.

GF, Glad to see your back as you started this thread!
I have my processor at the hydraulic shop getting the hoses set up and testing the pressures and getting it dialed in. Hope to have it back home in the next few days to do the final set up. I am sure there will be a lot of tweaking involved.

I ended up running a parker/commercial shearing 2 section pump (each section 15 gal/minute @ 1500 psi) and a haldex 28 gpm 2 stage for the splitting function. Powered by a 38 hp kohler gas engine.

After looking at the peak torque etc, this thing should run at 2400-2600 rpm. I utilized a prince auto cycle valve for the splitter (4" x 24" cylinder)and a two banks of parker valves for the other functions.

God, I hope this thing works! It's been a lot of work & frustration!

   blackfoot griz   we gotta have pictures  please

This is my processor..she's not pretty but she works. Got my new pump can't wait to get it on and see how much faster she goes. Still waiting for more parts, they will be here Monday then look out wood pile. I will let you guys know how it works.

Looks like a mean looking unit gorshi.  :D  As long as it does the job.  Who can afford to buy a new processor unless you are doing it full time.  ;)  I have not been able to do much in the way of firewood yet. Still waiting for freeze up which is hopefully coming this week.  I am estimating that I will have 50 or more cords of spruce alone to cut plus all the tops from my sawlogs.  The winds have sure done a number on our land this year.  I guess my old alpine will be grunting and groaning again cuz I can't afford to fix my old homemade skidder till the wood starts flowing.

Brad.

rs1626..

Will try to post some photos when the x#@$ thing does what it is supposed to do. I had a big setback w/the framing for the splitting base. It cruised through some small stuff, but bent from some big tough blocks. I'm about 75% of the way in getting the newand improved splitting base in. Then it's going to go back to the hydraulic shop... They incorporated a manifold that is supposed be a one touch clamp/saw motor/saw cylinder function. This is not functioning as intended. No matter what, it puts too much pressure on the clamp and there is not enough flow for the saw motor. Also, on the when the saw bar raises---the chain goes full tilt in reverse...a little disturbing! The guru at the hydraulic shop swears it should work like a dream. He thinks there may be an incorrect flow control in the manifold. I will take it in--with logs--and see if they can dial it in.
If not my plan B is, because I have one unused circuit & valve control, I may have them make the clamp a single function with check valves. This way once the clamp is down, all of the flow from that pump could be utilized for the saw motor and saw cylinder.

Talk about trial and error!

 OK blackfoot griz   I am building one I just started a couple of weeks ago had most parts what i did is run 2 pumps 1 directly at end of the motor shaft and another smaller 1 with a pulley and belt the bigger 1 runs saw and splitter smaller 1 runs clamp chain up and down and motor for log forward and reverse am going to try it out this afternoon to see if everything is working  will try to get photos today or tomorrow

Well guys I got my pump on..and I've got it down to 15 seconds splitting time which is much improvement form 62 seconds at first.  8) I can't haul wood fast enough to it. 8) So now that I've got the kinks out and most of the parts/pieces for the next one, it's gonna be time..once it warms up a bit..to build the next one.

Hope to get some updated pictures uploaded this week.  Got the three strand infeed conveyer mounts all built and welded on.  Got the folding live deck arms assembled, and will wait till the last to get them one due to how much space they require even when folded.  Also got the adjustable log stop machined and mounted.   Completed the operator workstation floor and have a operator console built and attached for the hydraulic levers, gauges etc.   I am going to be rebuilding the cutoff saw and attaching a new hydraulic motor that should put out about 24HP at 3000rpm 2500PSI.

Got the 28GPM splitter pump, Prince autocycle valve, and new hydraulic saw motor in last week.  Got new larger ports ordered for the splitting ram and will take in to have larger ports installed instead of the current 1/2" ports.

Gary

Sounds like your moving along gary what motor are you going to?

New 40hp Kohler motor should be in this week.  The new motor for the saw is a Cross hydraulic motor.

GF

Got a few pictures of the latest process this past week.

Picture of the beginning of the operator console made of 1/2" steel plate, the hydraulic valves will mount on the under side of the console, eventually it will have a metal shield in the front to conceal the hoses, and a seat to operate the processor controls. Axles and fenders will be mounted right in front of the operator console.  Its still up in there air if I am going to build a cab.

The new 40hp engine is at the Okla City dock and will get it picked up tomorrow.  Numerous other parts should be in next week including hydraulic strainers, filters, hydraulic flud level gauges, hour meter, some hydraulic fittings, another three spool valve.  Picked up the sheet metal to build the hydraulic fluid tanks, fuel tank, and covers and shields yesterday.

GF, how much did the hydraulic saw motor cost and where did you buy it? The project is looking really good.

Here are a few updated pictures

I like those controls, my multi-tek has wobble sticks.

I could use and would appreciate some feedback/suggestions.  On the processor I built, I am running a 38 hp kohler with 3 pumps. One is a two section Parker, each @ 15 gpm @ 1500 psi and the 3rd pump is a 2-stage haldex for the splitting function.

Everything works well...except the Parker .70 cu inch MG motor I tried for the saw function. It has the rpm but not the torque.

I have 15gpm & 1500 psi to try to run the saw function. Can anybody give me suggestions for a saw motor that will work? It is a .404 chain. I can get the saw section of the Parker pump rebuilt to increase it to either 2000 psi @ 15 gpm or 20gpm @ 1500 psi and still keep the works within the HP/torque available from the Kohler engine.


Thanks

hello all. i'm new to this site. hoping to build a fire wood processor. i have a learning and physical difficullities that slow thing down but not stop me. i'm a good welder with stick,tig and mig. i like what GF is building and i hope that i can get a blue print. i know with a plan and the know how everyone has here i can build it. GF i'm willing to pay for blue prints because i know that it will take a lot of your time to produce. i hope everyone will be patience with me as it is hard for me to grasp the mechanical end. with measurements and pictures i think building the frame will be easiest for me. any help will be grateful

Welcome to the Forum outback

Do you have any pics of previous projects?

GF,

What size bar stock did you use for the stationary "splitter bar" that sits behind and supports the moveable splitting wedge ?

Warren,  the back portion I used 1" X 8" solid stock.  The push plate is made of 1 1/2" this solid plate.  Hope this helps.

Outback, welcome to the forum.

The latest process I have made is getting the two 5000 pound axles installed.  I purchased all the parts individually to build the axles with the exception of the tubing, next time I would purchase the axles completed.   Found a good resource for trailer parts with about the best prices around at www.trailerpart.com (http://www.trailerpart.com).

Things are shaping up real nice GF, one thing's is for sure is it is the heavy duty model!
I was wondering how much it is going to weigh when done, that's some heavy steel you are using, can't wait to see it running.

Not sure what the completed weight will be, I am guessing right at the 10,000 lb range.  It does have some serious steel in it.  The bottom portion of the splitter section is made up of 3 pieces of 1" X 6" steel welded together to make a solid 3" X 6".   I did some testing for strength by pushing the 5" ram directly into the 8" backing plate with 3000psi until it stalled to see what would move, results were good nothing moved.   Wanted to make it strong enough in case I want to go to a 6" or 7" ram.

GF

Here are a few updated photos.  Starting to break everything down for paint (John Deere green).  Some of individual parts are painted and have alot still to go.  Working on cleaning individual areas of the processor and getting some primer on it to keep the rust down.  Should get the hitch built an put on in the next couple of days.

Some of painted covers, fuel tank and other parts. Decided to put a fuel sending unit in the fuel tank for a remote gauge on the console.

You're a pro, GF. It's going to be sharp.

Nice work!

What kind of paint sprayer are you using?

Norm,
     I am using a Porter Cable PSH1 gravity feed spray gun, I think I got this one at Lowes for about $100. I replaced the plastic cup on it with a metal one. I am using Anchor paint with gloss hardener.  Someone from the oil field several years ago recommended Anchor paint, I painted a steel fence with some gloss white about 5 years ago, and the paint still shines the same as the day I painted it so I was sold on it.  And the price for the paint is about $33 gallon which is much cheaper than some auto paints I priced, and definitly in my price range.  

Gary

Well it sure looks nice. Thanks for the answer.

GF, that is looking like a Grade A, top-of-the-line job you've done there! 8) 8) 8)

Completed the hitch and got it all attached today.  Hopefully can start doing some more cleanup and getting ready to do some more priming this week.

Gary

Gday

Gary You have put alot of thought and effort into it done a very tidy job ;)   ;D 8) and Im sure she will work like you planed and look a treat while doing it too Im looking forward to seeing it in action Mate  ;) ;D ;D 8) 8)

I am looking foward to it also.  It takes a while to break down each part to prep and paint.  I like to make sure even under all the bearing blocks etc that there is primer and paint.

Gary

gf .I to am building a processer. i noticed you ordered a new cross saw motor  .can you tell me the model number or spec of it.I checked their website .The fastest motor I could find was 3000 rpm

The processor is all dismantled and ready for the final paint.  A majority of the individual parts are painted and completed.  If the weather is warm enough this weekend the main portion will be painted.  Primer has all been sanded and dust removed, I will tack cloth right before painting.  I need to still lay out all the tarps to protect the floor etc from over spray and setup the exhaust fan since it will be painted inside (Oklahoma wind and dirt).  I will sure be glad to see the final paint applied and start the final assembly.

GF

Wow...that is some impressive work, Gary. I've never seen a firewood processor work but I'd sure like to see yours in action. Makes me realize how DANG ignorant I am! I've learned alot just reading these 8 pages and seeing your processor develop. I won't pretend to understand the hydraulics, I had enough difficulty trying to figure out the mechanical side of it. In this case, the pictures of the final product will definitely be worth a thousand words.

I don't recall ever reading a thread that pulled so many new folks onto the forum and by the way, Welcome to all the new folks.
Thanks for taking the time to share this. Like everyone else, I'm looking forward to seeing the next installments on this project.

I finally finished my processor after a ton of trial and error. I have run 2+ cords through it.There is still some tweaking to do, but it does the job.  I posted some photos and comments to my gallery.

A friend took a short video... not sure if this will work, but, here is a link



http://www.youtube.com/watch?v=7WXptIZ4wDI

I fixed your link.  ;)

Way to go Blackfoot :) :), looks like it definitely will do the job.  Nothing like seeing something work after you complete it.

Gary

          This is the best forum I have ever found! It took 2 days to refind it though!The search didn't help any. You've all posted some real informative videos and given some real detailed information.
          I've built a processor also about five years ago, but I wish I'd had some input from fellows like you all. It would have made it a lot easier. The experience of live and learn is worth some thing though. The head scratching, plotting, and planning is all part of the fun.

Gday

And welcome to The Forum Auger  & Blackfoot ;) ;D ;D 8) 8) there is a lot to be said about live and learn  ;) and It is awesome to have a great bunch of people to share it and what we know with people like we do here Mate  ;) ;D ;D ;D 8) 8) 8)

Blackfoot

That's very impressive.I'm in the process of building one.Can you give me some info on  hydraulics you used? How many gpm,is it pto or motor driven ,plumbing.What I don't under stand is how does the saw start turning and lower at the same time.Do you plumb those two together.Any info you can give me would be great.Im a good fabricator but suck at hydraulics

I really enjoyed talking to blackfoot griz, and exchanging ideas and thoughts. He also did a great job fabricating his processor.  I also had some reworks in the middle of the build it was all trial and error as I went, and some tweaks once completed.  Below are some photos before paint and after paint with some of the parts being installed.   I still have some work to go in getting everything put together and all wired and plumbed in.

Gf the next question is  ;) How Much Mate  ??? You have done an Awesome Job ;) ;D ;D 8)

Regards Chris

       GF    You've done one fine job on the processor, are you a professional painter?
If not you sure could be. You've done a very nice job with the pictures an explanations. Thanks again for sharing.

NICE!!

Quote from: Meadows Miller on March 23, 2011, 02:58:26 AM
How Much Mate  ???

Rough estimates are right around $12,000 so far, that is with everything new including the hydraulics and the 40hp Kohler.  I have all the receipts together and plan to add everything up at the end of the build. That was one reason the build has taken a little time I paid for things as I went, plus it gets depressing constantly spending money  :-\ and not yet seeing a return on the investment.  I dont like to owe a bank any money  ;)

      GF    You've done one fine job on the processor, are you a professional painter?
If not you sure could be.

I am not a professional painter, I did paint and body work in my earlier days.  Three coats of enamel paint were applied with a gloss hardener additive.

Working a full time job, and running a sawmill on the side, often does not leave alot of time left to build a project like this, guess that is also why it has taken so long.

GF

WOW, that's impressive. Tonto.

Started on my new project building a hydraulic firewood processor.
This picture shows the infeed conveyor that is 15' long the main frame is made of 3" square tubing

(https://forestryforum.com/gallery/albums/userpics/11029/296/Processor4.jpg)

This shows a porttion of the splitter area still in the process of being built.  The hydraulic ram is a 5 X 24.  The splitter carriage rides on the 3" x 6" frame and uses two 3" x 3.5" solid steel
rollers to help eliminate wear on the bottom as the logs are split.


(https://forestryforum.com/gallery/albums/userpics/11029/296/Processor5.jpg)



(https://forestryforum.com/gallery/albums/userpics/11029/296/Processor6.jpg)

The chainsaw bar is 29", and will be powered by a hydraulic motor and eventually powered by a hydraulic cylinder.  Eventually a six way and eight way splitter will be located in the back portion and will be adjustable up and down with a hydraulic cylinder.

Still have a ways to go until its completed.

would it be possible to get those pictures sent to me so i could print them, What a nice job and I would like to make one just like it. Also a list of what pumps, controls, and motors that you used.

Thanks

@ GF. would you be interested in selling your Blueprints for a reasonable price, along with a list of parts, cylinders, hydraulics ect, ?

Once I get the processor completed and the bugs all worked I can make a list of everything that was needed.  I would like to make sure everything is going to work correctly before I give out alot of the details. I would like to prevent giving out any bad information.  The parts can get expensive and if something is incorrect it could cost several hundred dollars to correct, I have done this myself already on a couple of items on this project.

I did get all four of the work lights wired up, fuse panel and switches installed for them, two facing foward for the infeed side, one right into the cut and split chamber, and one on the backside of the 6 way splitter.  All the wiring was enclosed within the steel frame tubing used for the operator cab.

Hope the weather warms back up I have to still paint the 6 way splitter, splitter plunger, hydraulic cylinders and some other parts.  The past four days its been in the 30s and 40s with light drizzle.

GF

All the hydraulics and electrical are completed, had to order a new auto cycle valve over torqued the fittings and cracked two ports on the valve body a $300 mistake  :-X.  I am working on completing the trough conveyor and the second section of the live deck, and then it will entirely completed.

Added an electric switch on the back side of the spool valve for the hydraulic saw so the bar oiler only works when the lever is pulled and when released it stops.

Tested all three hydraulic circuits at once put 3000 psi pressure to the splitter until it was bypassing engaged the hydraulic saw with 1500 PSI going to it and pulled the log clamp lever until it kicked in the 1500 PSI bypass on that valve, motor seemed to handle all three at once without any problems.

All the vinyl lettering (stand clear, caution, Twisted Oak Firewood Procesor, etc) are completed, and applied. 

Hope to get some updated pictures posted this weekend.

Gary

Below is some updated photos, still need to finish the live deck, and the trough conveyor.

Couple pictures of the saw chain oiler tank.  The clear hose is used see how much oil is in the tank. Its has a adjustable valve to adjust the amount of oil flow going to the bar.

(https://forestryforum.com/gallery/albums/userpics/11029/2169/IMGP0464.JPG)

Here are some picture of how the bar oiler switch was built, it connects to the spool valve that runs the saw motor, when you pull the spool valve, it pulls the 1/4" rod that goes to the back of the valve through a bushing where it triggers a switch to start the pump to apply the oil. When the lever is released the switch turns off.  I used a DPDT momentary switch, could have used a SPST but already had this one.

This shows the log splitter section.  A piece of 3/16" sheet metal bolts on top of the splitter mechanism, should a piece of wood be cut all the way before the ram fully return the cut log will rest on top and will fall into the splitter when its fully returned.

This shows two of the three hydraulic pumps the processor has, these two run the hydraulic motors, clamp, bar ram, and 6 way splitter ram.  I turned down the back side of the lovejoy connector on the lathe, I then turned the inside of a solid sheeve to fit tightly on the lovejoy connector, its attached with 4 grade 8 bolts.  The two stage pump is located on the other end of the motor.  Saved  alot of money by not having to have a special built sectional pump.  Plus if one goes out I can replace it with any manufactures pump.

Absolutely amazing. To use a quote from my granddaughter "you got mad skills". Tonto.

Almost too nice to get dirty. Very well done GF.

Awesome! I can't wait to see it eat some logs 8)

Great looking job when do you think you will get it dirty?  What kind of pump did you use for bar oil?

Great Work.. Looking forward to seeing this work... :)

Quote from: rs1626 on May 02, 2011, 12:19:56 PM
What kind of pump did you use for bar oil?

rs1626, I am attempting to use an inline Carter electric fuel pump that is rated 10-14 psi, hopefully it will work, if not I will have to come up with another plan.

Gary

I'm planing on teeing off the return line from the saw motor with a needle valve controling the flow.Everytime the motor starts its getting oil to the bar.Supposed to use around a gallon of fluid a day of use.and the oil is always around the same temp

 GF asked me to post some pictures and comments on the stuff I used to make my processor. So far, I have run about 10 cords through the machine. Everything functions as intended. The only issue so far is I had to replace orings on a NEW prince auto cycle valve. While this thing is not pretty, it is doing better than I thought it would.  I can tow this thing around the place with my tractor. If I need to go a longer distance it's pretty easy to put the processor on a trailer. I stole the wheels off my bale wagon and I will have to swap them back when its time to bale hay ;D

(https://forestryforum.com/gallery/albums/userpics/21659/3401/processor_photos_002.JPG) This shows the pumps The first is a Parker 2 section pump w/a common suction line and 2 presure ports. Each section is 15 GPM @ 1500 PSI. The third pump is a Haldex 28 gpm 2 stage. I run the Kohler 38 hp engine @ 2400 rpm

(https://forestryforum.com/gallery/albums/userpics/21659/3401/processor_photos_010.JPG)
I used a winch for raising/lowering the knife. Works fine. Also makes it easy to change knives. For the adjustable log stop, I used a leftover chunk of # 80 roller chain


(https://forestryforum.com/gallery/albums/userpics/21659/3401/processor_photos_009.JPG)
For the bar oiler, I used a NAPA fuel pump rated at 1-4 psi. I had to add a control valve because I was getting too much oil. The tank is a radiator over flow. at the bottom left, you can see a tab welded to the shaft. When the saw is all the way up, the tab contacts a "Pickup door interior light switch" cutting the juice to the pump and stopping the flow. So far so good!


(https://forestryforum.com/gallery/albums/userpics/21659/3401/processor_photos_007.JPG)
This shows the "manifold" that makes the one-touch clamp/saw motor/saw cylinder work. So far, I am very happy with this thing. There is one pressure line and one return line to the manifold. From there fluid is diverted to the clamp, saw motor and saw cylinder. To activate pull one lever. The clamp comes down, the saw motor starts and the saw cylinder begins to extend. When the block is cut through--push the same lever and the clamp goes up, the saw stops and returns to the upright position. There is a flow control which enables me to slow the cylinder extension speed but the return speed is quick.
The clamp is part of an old John Deere trip plow. The saw motor is a Danfoss .77 cu inch with a 3/4 shaft. The 13 tooth chain sprocket is held on the shaft with a Martin 3/4 QD bushing. So far, so good

The controls from left to right. The first two are the Prince auto cycle valve. Next is the one touch clamp/saw motor/saw cylinder. Next, the log trough motor. Next Live deck. Next cylinder for raising the live deck(plugged not used for now) finally a detent valve for running a hydro motor on the conveyor.

I wish I could have one of those manifolds, that would be the way to go, thats beyond my hydraulic capabilities.   Looks great, thanks for posting the pictures.  Nothing like building your own equipment and know you dont have any proprietary manufacturer parts.

Gary

Hope to get some pictures and video uploaded some time this week, the processor is complete and I have put about 4 cords of wood through it.

GF

This is a great build.... Great pics!


Question, where did you get the rigid hyd. lines I see in the last pic?  I could use some for an idea I have.

Video, we need a video.

blackfoot griz where did you buy the manifold for your processor and what was the cost  thanks  Truman

I got the "manifold" from KLS Hydraulics in Missoula, MT. I will have to dig up the paperwork to determine the cost. (I think it was around $125 but will need to verify) It was actually a money saver. It eliminated at least one-maybe two control valves/levers and all of the associated hoses fittings etc. More importantly, it makes it easier to operate...advance the log to the stop, pull the lever and the clamp comes down, the saw motor engages and the cylinder extends making the cut. Once the block falls is cut, push the same lever and the saw motor stops, the clamp comes up and the cylinder retracts. Where I did make a goof was that I determined that I needed a flow control valve to control the cylinder extension speed. I put it right near the manifold which was a wrong move as it is on the other side of the machine from the controls. I will change this and move it to the operator side. That way you can control the cut speed even during the cutting process

So far, I have run about 25 cords through my processor--and this portion works great. If I had to do it all over, there are a lot of things I would do differently, but the one touch clamp/saw/saw cylinder...in my opinion is the only way to go.

I am second guessing the Prince auto cycle valve tho...not very happy with it it...have had to replace O rings and it seems to be very touchy...it works as intended sometimes... I am rethinking this portion...if anybody has suggestions, I'd love to hear your suggestions!

Finally put a youtube video together along with some pictures to upload, its my first attempts at using the processor and still getting used to the hydraulic levers.

Great looking job GF  looks like you have a winner

Thanks!  great job.

Im very impressed!

Great work GF :)

This thread is the one that brought me to the FF.  I was researching firewood processors about the time this thread started.  Been watching it ever since.  I have an idea about how much determination and hard work it takes to complete a project like that.  I must say I am very impressed.  You do your best to get it right and perfect the first time right down to getting the google ads on your first youtube video.  Very impressive.  You deserve a million hits.  Ill go check out some of the ads over there.. haha Hmmm.. the ads probably come from the soundtrack,, somthing I wasn't aware of when I made the comment

Great vid!   I do have one minor wish...  that rig needs a hydraulic lock out for when your hands are in the danger zone.  It may have one I don't see.   I would hate for you to smash a hand with an errant pull of the controls or kids or animals or (insert oddball situation here).   Just throwing it out there. 

Congrats on your project.  She's a beaut!

GF, How do you tighten the chain?  I looked but could not see an adjusting screw.  Is the mounting plate assembly for the saw your design? 

Great job on the metal fabrication, you mentioned having a lathe, do you own a metal milling machine as well?

The chain tensioner is the same design as what most chainsaws use. I milled on a slot and built a small square block that had a pin machined on top, I then drilled the small block and tapped it.  I then took the bolt that will be used to tension it and machine a small groove around the top part for a clip to fit in, this prevents the bolts from going in and out while you tension it.

I did design the mounting plate it was machined out of 1" thick and 4" wide steel.

I do have a milling machine definitly could not have done a lot of the things I needed without it.

Hope this helps.

wow all I can say is i'm really impressed.

Outstanding work and a great thread, GF!!! I've enjoyed following this from "cover to cover".

GF do you have prints and material lists developed yet?  I would be interesting in purchasing these items from you

Does anybody have pictures/ideas of a conveyor system that they are happy with?
I converted a beat up hay elevator into a conveyor but the chain keeps breaking and the whole thing is about to fall apart!
My processor is working fine, but I'm tired of fighting my crappy conveyor.
I keep changing my mind on building a chain or belt conveyor...

Any ideas/suggestions woud be appreciated!

I bought a little firewood processor last fall and it has a little elevator on it.  If i were going to build a bigger one I think I would use the same concepts.  two roller chains with the bolt on tabs and bars.  the bars on mine are plastic and hold the chains  just off the metal of the trough.  The chains are driven by a little hydraulic motor at the bottom and the sprockets at the top are spring loaded.  This little elevator works very well but only piles the wood about 10 ft high.  Im not sure how i would make the bars but i would consider a hard wood.  I dont like the idea of using metal becuase of the metal to metal contact. here is a video of a machine just like mine

http://www.youtube.com/watch?v=C-G54L-Pag0

GF, I am curious if your saw is cutting as fast as it is capable of in the video? I'm used to the saw on Ponsse logging processors, those things cut really fast.

Hey all,  I'm new to the forum here.  I've been searching around for either an inexpensive firewood processor or info on building one.  I've been doing firewood since I was a kid so I'm no stranger to a splitting maul or a chainsaw. Unfortunately I lost an arm in the military 5 years back so I'm not quite as comfortable with the whole process as I once was.  I made a chainsaw attachment for my prosthetic so I can still cut wood and I made a wood splitter attachment out of a hay hook so I can lift 100 pound oak blocks onto the wood splitter and run the hydraulics.  Unfortunately the whole process is hard on my arm, my prosthetic, and the remainder of my left hand (shrapnel tore through it taking a couple fingers with it).  I need a better solution.

I've been able to check out a Dyna firewood processor (http://firewoodprocessor.net/dyna-firewood-processor.htm (http://firewoodprocessor.net/dyna-firewood-processor.htm)) in the last couple days.  Maybe its just me, but I don't see these (and the other low end models online) costing 25k to build.   A power plant, a fair bit of steel, some pillow blocks, hydraulic lines, hydraulic motors, rams, etc.  I dont need something like GF built, thats a bit beyond my abilities anyway. If I build it I just need something basic for my own needs.  A feeder for the log, a hold down, saw bar and motor, and wood splitter. The live deck and adjustable splitter are nice, but not totally necessary.  Other than figuring out the hydraulics I don't see it being all that complicated, just time consuming.  I can weld and fabricate ok (I relearned left handed).  I have a small amount of experience with hydraulics.

A few questions for the more experienced.

How big should the power plant be? Would a 25hp Robin Subaru work?

How big should the hydraulic pump be for a motor that size? 1 stage, 2 stage? Difference?

What size hydraulic motor to run the log feeder chain (like on the Dyna)? What kind of chain is it, what exactly is it called (it looks like some sort of farm implement stuff).

I was thinking of a 4" x 24" hydraulic ram for the splitter. How big should the I-beam be to take the load?

How big should the ram be for the hold down?

What kind/size of chainsaw bar is best? What size sprocket/motor to run the bar?

I have a lot more to figure out, but this is a decent start.

I've been able to get a lot of information from the forum here and around the web. Still, I dont think I have run across an established set of standards for a smaller processor like so many of us have been looking to build.  I'm hoping some helpful folks here can jump in and offer some experience.

Thanks in advance for any advice.

logboy, Welcome aboard. Thanks for your service and am deeply sorry that you have had to endure the pain, suffering and your losses.  I admire someone like you who doesnt give up, but finds the desire to keep on making good for themselves. I dont have all the answers you need so I will not try. There are others on the FF that can definatley answer your needs. Thanks again and good luck with your project, bg

Oh man, sorry about your troubles.  Huge sacrifice you made there.  We are grateful for your service, even up here in Canada.

Regarding building the processor,  I was thinking the same last fall but I just could not make the time to build somthing.  I have all the welders and shop and everything I need but still couldn't do it so I bought somthing and I have no regrets.  It is a very light machine but quite productive. I spent about 16 K for the little processor and deck.  I think it would be adequate for processing 500 to 1000 cord a year.

Welcome to the forum.
Here is a link to a new development of one of our many favorite sponsors, LogRite.

https://forestryforum.com/board/index.php/topic,51087.msg739111.html#msg739111

The video shows it to be a pretty handy arrangement of log handling equipment that I found quite intriguing.

I too am honored by your service and sacrifice in the military. Hope this venture turns out well for you.

Thanks for the replies everyone. I'm pretty good in the log handling department.  I have a Bobcat for moving stuff around and plenty of hand tools (love the LogRite stuff) for moving logs for my Lucas Sawmill and lathe turning and handling log rolling logs (I'm one of those old-school lumberjack types).  Because of this its not necessary for me to have a live deck or any of the extras that these 25k processors have. I just need a feeder for the log, a hold-down, saw bar, and the splitter. I could probably get away without the saw bar by just putting my Stihl on a hinge. I've seen this setup on youtube, I'm just not sure how I would go about making it.

http://www.youtube.com/watch?v=bAckm2YdLEQ&feature=channel_video_title

I just want to alleviate using a chainsaw left handed with one arm (already caught my chaps twice) and lifting heavy blocks with my arm/prosthetic.  I have an old elevator the previous owner left on my property that will probably work for moving the firewood out of the way. I bought the processor plans from Millers Woodcutting to give me some ideas. Its a start, but not nearly as heavy or fast as I would like. Hence all the questions above.

Logboy,

1) Welcome to the forum

2) Thank you for your service.

3)  A 25hp power plant will work.  However, horsepower equals speed.  The speed will depend on size of pump, cylinder size, saw motor displacement, max pressure.  If you Google around the various hydraulic manufacturer websites, you can pick up the formulas to determine max pressure/volume for a given HP input.

If you've already discovered LogRite, you might check out their section here on FF. Scroll way down on the Forestry Forum index, or try here:
https://forestryforum.com/board/index.php/board,58.0.html (https://forestryforum.com/board/index.php/board,58.0.html)

Look for a thread on "firewood processor" for a video of their new processor. It takes care of a lot of the processing, however, you still use a handheld chainsaw to block up the logs. It might be something you could modify to mount a chainsaw on?  It's certainly less expensive than some of the big processors.

Hello all. New to this forum but no stranger to the timber industry at all. I joined this forum because of this thread, found it while looking for info on processors and just read all 11 pages.

GF, is the splitter cylinder only attached to the splitter base at the back end or is it also attached at the rod end also? I couldn't tell by the pictures. I did see that the pusher isn't attached to the base, it just rolls along on the rollers. What keeps it from riding up while splitting?
Great job by the way. Wished I had 1/2 the motivation that you do.

Welcome to the forum junkfxr.  The splitter mechanism was built seperate its much like a normal log splitter.   The bottom the the push plate does not have anything to keep it from rising when splitting.  The push plate is made from 1.5" thick plate.  On the top part of the push plate you maybe able to notice there are two ears that protrude out, these ears fit inside of some 3" c-channel.  

On the backside of the push plate there is a large portion of steel  made of 1" x 6" plate that is welded to it, this is where the ram attaches and this also keeps the push plate square with the bottom where the rollers are located.  On the top portion there is a steel frame made from 3" heavy wall square tubing that is about 36" and the width of the ears on the push plate. This frame bolts to the push plate portion with 15 grade 8 bolts and this rides along in the 3" c-channel at the top.   This is the frame that prevents the push plate for rising or twisting when you split a log.  Below are a couple of pics that may help out.

Hope this helps.

Yes, it sure does help. I wasn't looking at the top, just at the bottom like a conventional splitter. Thanks.

Hi everyone just trying to get some info for everyone that is after it.

This is the model of chain i am going to run WH-82 in the in feed deck

What rpm and toque needed for the log deck, in feed and out feed conveyor?

Any one in Australia looking at building a smallish firewood processor for aussie hard woods looking for someone to share ideas/supplier with.

And Welcome to The Forum Hilux it good to have another Aussie on board  ;) ;D ;D 8) 8) where abouts in Australia are you from and how old are you Mate  ???

Johnny come lately here WOW GF!
What the heck do you do "for work"? I'd like to grow up to be like you but uhoh I got 8yrs on ya. Really exceptional work, can't express enough envy. Your (mill & splitter) projects are both at the top of my pipe dream list to build. How about some shop pics, I imagine that too, will pith me off :D What's next on your build list? jet plane, space shuttle II, D-11? Thanks for letting us in on your fine work.

My full time job is dealing with computers 25+ years, now I do architecture and design for computer systems and networks (boring).  To be honest I cannot stand sitting at a desk but its always been a job that is out of the weather, has stability, and pays the bills.

Not sure what the next build will be, with the price of steel now I have slowed down.  Been thinking about building an splitter to build split rail fencing, another thought is to build a stump grinder that would go in place of a bucket on a backhoe.  Right now I don't seem to have enough time to use the things I have built. 

Hello everyone, i'm new in this site, my name is Roberts.
I want to make firewood processor similar this one, but i will make it with two electric motors. One is for oil pump and second is for saw blade. I just now blueprint a simple model (just for a look, without any exact dimensions, just to understand the idea), of how the saw blade will be connected with electric motor, and i want to know your opinion, is this bad idea or not, or what could i change there to advance it. Here are some photos below:

Welcome to the forum.

Usually the saw system you show is referred to as a slasher.  Such a system is also referred to as a buzz saw in the bucking of firewood, with flat belt driven or PTO driven.

Up to what diameter logs are you figuring into your design? And what do you have in mind for a saw blade?

Baker, one of our sponsors here, has a slasher.
http://www.baker-online.com/Log_Cut-Off_Slasher_Saw_Log_Cut-Off_Slasher_Saw.aspx?productid=2646&categoryid=106

beenthere
Many thanks for the information which you told me, based on Saw name, now I can search in google more info about slasher, but actually BAKER have a great idea, because the weight adjusted on both sides, so the hydraulic cylinder will not need so much energy to lift up slasher. And it is more easy to build it when electric motor is on the same frame as the saw blade.

In response to your question, The max diameter of log will be about 28 cm, so the saw blade will be 80 cm.

Weedman7,
Welcome to the forum. I think you write with an accent. Where are you from, if I may ask?
Den

I'm from Latvia, it's in the center of Europe. I'm only 17 years old, my father have wood processing companie, and I want to make a firewood processor to supplement the companie. He already have firewood procesor from PALAX, it's totaly hydraulic. And 3 simple firewood proccesors. I decide to build firewood processor to improve my skills in engineering, welding, etc. So i decided to build processor similar to GF's. Should i make new topic as GF did? Add photos to show progress? I apologize for my accent, i'm not very good at English.

Good on you for designing a firewood processor. And your english is quite good. No apologies needed and glad to have you aboard, accent and all.  :) :) 
Am sure that Den feels the same and also wants to hear more from you about your processor development and about your experiences.

I'm with beenthere. No apology needed. Your English is fine. As for a new topic, maybe you should start a new one titled slasher. GF's is long and I wouldn't want to see yours buried.

Welcome to the FF weedman7. Don't worry about your accent, I have less trouble with yours than the guys south of the mason-dixie line.  :D

Weedman...I would mount the motor on the moving frame...maybe a plate offset from the bottom of the swingarm...with the motor mounted to a fixed frame and the blade moving up and down, you introduce more dynamic stresses on the entire drive train...even with a spring tensioner to keep belt tension fairly constant...methinks it would be easier to maintain as well...maybe fewer bearing failures...

Thanks for greetings :)
Allright, I will make new topic, this one is too much mixed up. And talking about slasher, i'd thinked over it, and decided to build firewood processor with one electric motor, who will be combined with circular saw and oil pump, all on one axis, taking the idea from PALAX.

I will finish draft this month (3D model with all correct dimensions etc.), and when i'll finish at least skeleton (that could take 1 - 2 weeks) then i'll come back to this awesome forum to show my progress.

Gday

And welcome to the forum Weedman  ;) good drawings and idea on the firewood slash saw but like Zopi said mount that motor on the frame counter balanced over the piviot point and id also mount the Hyd ram on the other side to reduce the stroke needed and reduce cycle time Mate  ;) ;D ;D 8)

Regards Chris

GF,

I have been reading your post while deployed to Iraq. I'm now getting ready to head home and it really has inspired me to fire up the welder and get to fabricating. But I was wondering if you had a list of parts you used? If you had anytype of dimensions/ blueprints? I can't really see everything in the post (videos and links) due to are limited internet access. I will be doing a lot more research once I return home so any information really helps out.

Thanks
Joel

I did not create any type of parts list or any type of blue print, I just bought things as I went along.   About as close to a part list I have is all the receipts of everything in a folder.

GF

Thorracing01,welcome to the forum and thank you for serving our country.

Hi Guys,
First things first...Two thumbs up GF  8)..nice processor.
I'm in the process of rebuilding my processor to accommodate my injury. I only have 50% movemnet in my one arm. So my processor needs to be able to be operated with one hand.
So I am looking for info on orbital motors to turn a 4' blade and pump. Also a gillateen or rocker arm??
Any suggestions on which to use. I have researched but am unsure. So if anyone has any info/suggestions all are welcome.

And welcome to all the new members.

Gorshi,
It seems like most commercial processors use a rocker arm--Cord King, CRD etc.

Could you use foot petal controls for some of the functions...like on a skidsteer?

tractormaniac here,hope your ok,and life is good. Your wood prossecor is the cats meow! One of the best made Ive ever seen.I also, like so many others would like to have prints, measurements and where to and what parts it takes to build a simmilar prossecor, I could maybe build one but with your help and info would be a dream. thanks alot

Welcome to the Forestry Forum tractormaniac.   :)

Welcome to the forum tractormaniac.  Also  make sure to keep up with the thread "building a firewood processor", in the "firewood and wood heating" section, jaybe_2 is building a firewood processor also and its looking great. 

I made a couple of modifications and adjustments to the processor recently.  One modification was I tapered the back corners of the splitter box.  When splitting larger blocks of wood it would seem to bind on the corner, after the modification this took care of the problem.  Another modification I made was were the split wood came out the back, it would build up bark and debris is the box area after the split.  I went in with the plasma cutter and cut some 1 1/2" slots, the debris now falls straight through. 

Another adjustment I made was to the autocycle valve for the splitter, the factory setting was not even close to what I needed, it would detent out and return when it hit around 900 PSI of pressure.  After adjusting the autocycle valve it now works correctly even with oak with large knots. Trying to split hickory or pecan with knots 6 ways is another story.  Before I was not at all impressed with the autocyle valve after the adjustments it seems to be working the way I think it should. 

GF

Congralulations to you GF and Jaybe on your processor builds both units are remarkable for the quality of the build. My firewood business is based in Christchurch New Zealand known for our earthquakes of recent times. We process approx 3000 cords of wood each year, currently use saw and splitter. Have tried a Bindinburg ssp420 and Timberwolf both excellent units  but our logs are up to 36in dia so a self build is possibly the only way forward. Christchurch as a city consumes approx 25000 cord a year. We  have Hailke Pilke X47, Multitechs, Blockbuster, based in our region. Anyone who can steer us in a direction towards a factory production unit would be a help. Cheers Andy Thomson.

GF,
I know I'm kind of digging this thread up but I had a few questions.

Do you have any updated pictures of the things you have modified? Also do you have any video or pictures of the live deck folding in and out? I have a lot more questions but really been studying your pictures try to pick out all the details.

Thanks
Joel

I dont have any pictures of what was modified.   I made some mod change to the splitting box near the six way splitter from the original desing and also adjust the hydraulics pressures and auto detents.  I fold and unfold the live deck using the forks on my tractor, I thought about making it hydraulic but since it required my tractor to load the logs when I use it, I thought I would just use the tractor do that also.

Gary

GF,
I sent you a personal message. I have a lot of questions I would like to ask you.

Thanks
Joel

Thorracing01
Welcome to the forum.
We'd be interested in your questions too. ;) 

Post 'em up.

I would feel better if I got the go ahead from GF. I feel a lot of them are simple(dumb) questions. So I'll just wait to see what GF has to say.

Well it has been about 8 months since I last used the processor, its time to bring it out and start processing some firewood. 

GF
