Title: Router sled for surfacing slabs
Post by: Crusarius on February 06, 2019, 01:04:25 PM
Lets see what you got. 

I made one out of minitec extruded aluminum I scored from the scrap bin at work. It worked ok but the amount of friction was to much for my liking. Great thing about it is how forgiving the alumiunm is when you hit it with your brand new carbide router bit :)

I am now wondering if buying a 1200mm linear bearing and using that for the bottom rails would work well. Could still use the minitec for the cross pieces. 

Part of the reason I ask this is because I am contemplating trying the linear bearing on my mill mast. If it does not work the way I want it to there I would like to be able to use it elsewhere.

My setup was a quick and dirty one trying to make slabs for my wife's Christmas present creations.

Here is the router sled I slapped together.

Here is the complete slab I was finishing. If you look closely you can see what a 2" carbide router bit does to aluminum when you slip :)

I just talked to dad about us building one of these out of that 80/20 material. The stuff is kind of pricey buy I like the idea of it being cut right, and square when you get it. I'll be interested what other people come up with. 
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 06, 2019, 04:07:47 PM
the 80/20 worked great. If I took a little more time and came up with some better bearing materials it would probably work just fine. currently the plan may be to stick with it if the linear bearing works on my mast. Otherwise it will become really smooth router sled.

Thats nice. I keep thinking about putting it on my mill bed to.

I see you do lengthwise to. I watched so many videos of ppl going across the grain instead of with it. I liked going with it alot better.

Made mine with scraps, 5 mm plywood bottom, 3/8th plywood side that traps (fences) the router in between, 2x4 frame on sides.

Thanks for the pics doc. that looks sweet. I keep wondering about making it height adjustable. the last piece I was surfacing started out tall enough it worked but I ran out of cutter depth before I was at the desired thickness. I had to reshim under the board to bring it up high enough to finish it.

If I had height adjustable life would have been much easier.

when eventually get to that point, I'm going to use my sawmill rails for fore/aft movement, and get some extrusion for the frame and cross slide, with some aluminum plating for the router base and sq tubing for horizontal movement. i figure why build some other rail sys, when the mill rails and frame are already built and cut the same slabs i will be flattening. kinda like ianab did.

I have considered doing that with my mill but I don't have a compelling need for it, although it would be fun to do and nice to have.

My dilemma with making one exclusively for the mill bed is the problem with my mill being portable and not setup in a building or under cover. May not even be near electric. Usually wood working is a rainy day or winter project.

But if you made one for the mill and had a set of rails you could just bolt to the table its a win win.

So here is a question for everyone who has used a router sled to surface boards.

Why is it I always see ppl routing across the narrow part of the board, usually across the grain? I found with my setup running with the grain produced better results and was quite a bit easier and faster.
Title: Re: Router sled for surfacing slabs
Post by: doc henderson on February 07, 2019, 08:17:24 AM
I would say it is because you need a well engineered sled to go across, and it is easier to make long solid rails, as your actual sled may sag in the middle if the span is long.  All about materials and engineering.  I made mine in less than an hour and that seemed to be the easy design.  Lots of great other ideas on this thread.  If I did lots, I would consider a more industrial design.  I also made a sled that could suspend a chunk of wood like a lathe, and rotate it slowly to carve it down with a router prior to putting it on a lathe.  It uses the same sled part.

1" round linear bearings on new 1" ground shafting will slide like its on ice.  The shafting is hot roll mild steel with a ground and oiled finish and is used for sheave shafts and so forth.  Industrial distributors like grainger or maybe MSC should sell it by the 8ft length in a waxed paper tube. Itll look chromed but is just ground.  Perhaps some of the better metal retailers too, such as yarde metals or speedy metals.

Ebay chinesium linear bearings should be about $15ea
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 07, 2019, 08:58:01 AM
I actually just ordered a set of 20mm x 1500mm linear bearings yesterday off ebay cost $83. Free shipping. That is going to get used on the mill. If it doesn't work there it will become my router sled.

I also ordered 6 cam followers for V2.0 sawmill playing.

Maybe the cam followers will work for router sled. I have wondered about just a nice flat table and rollers under the cross sled.
Title: Re: Router sled for surfacing slabs
Post by: doc henderson on February 07, 2019, 09:03:07 AM
I do not mind the little bit of friction as I push the router by hand.  gives some control so router does not run away or go too fast.  I think if the router is well secured to the frame, then less friction would be nice

Have you seen the linear bearings offered by 80/20 that fit right on their extrusions? I believe I am going to use 1"x2" extrusions for the main rails with the linear bearings on top of those and have the sled portion made like what most people do with a box made from lumber. This would allow me to have 2 or 3 different boxes for different widths of materials being planed and not break the bank. Hopefully I'll have a better idea and maybe some pictures in the next couple weeks.
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 07, 2019, 01:12:45 PM
are you talking about the white HDPE linear bearing or do they have another style?

I have thought about putting a set of wheels on the cross slide that drop into the groove on the 80/20. Then maybe just a wheel on the other side that rolls on the table. 

When I start surfacing the big boy slabs I have cut then I will probably put alot more time and effort into this. Right now, I am really looking forward to seeing other ppl's setups.


Thanks everyone for participating.
Title: Re: Router sled for surfacing slabs
Post by: DWyatt on February 07, 2019, 01:28:04 PM
Yes, just the ones with the HDPE pads. I originally thought about using wheels, then I watched one run and the amount of saw dust (chips really) is incredible. I would fear that with wheels that fit in the T-slots of the 80/20 you could possibly fill the slots with sawdust and your wheels could ride up on the sawdust causing issues with the finish. 

Then again, I could just be dreaming up problems that don't happen in practice. I feel much more comfortable with a sliding motion that is constrained in two directions (as the 80/20 linear "bearings" are) that will cause you to either push dust out of the grooves or be come hung up on the dust in the grooves. Either of which would be better than rolling over the sawdust and it impacting your z-axis. 
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 07, 2019, 02:17:26 PM
That may work nice on the cross slide. slide the router to where you want and there should be enough friction to hold it in place then just slide the rails on top of the other rails.

But if you made one for the mill and had a set of rails you could just bolt to the table its a win win.
that is kinda my plan too. have a section or track, same width as my mill, say, 3-4 4' sections of frame/track extensions. for mine, it will require the tractor and forks to move my ext sections, but it will require the tractor and forks to move the slabs too.

They do make sticky back UHMW that comes in rolls as if it were a a teflon tape.  One could build friction slides and then plastic them up for low drag.  


A simple Z axis height control could be to make a few bushing plates of different thickness so that your router sits on an adjustable height standoff.  For more plunge you just pull one out and wack another pass.

I like cam followers, but much care would be needed to brush the tracks ahead of each roller so the sled doesnt bump up over a chip and transfer the Z axis flaw into the cutter point. Maybe mounted paintbrush heads or constant air via some perforated pex tubing along the sled frame.  

Title: Re: Router sled for surfacing slabs
Post by: Hilltop366 on February 08, 2019, 09:25:30 AM
Wood waste on the rails would be a problem, ways to reduce the amount of wood that gets on the rail would be best.

Some possible ideas?

The router set lower (lower cross sled) so the cutting was done below the length wise rails.

Some shielding to guide the waste away (think lawnmower).

A flexible curtain or brushes with dust collector to remove waste.

Mike, you always have some of the simplest ideas. a pile of C washers that can be removed as necessary. That would be nice not have to constantly fight with the router height adjust.

A single layer of uhmw will definitely fix the friction issue.

If I did a roller that rolled on anything there would be some type of a wiper. that is critical. even on my sawmill the one time I ran it without I regretted it.

Post by: mike_belben on February 08, 2019, 02:25:02 PM
Well, i try to be a simple guy
 ;) 


High mount gantry rail would help reduce the trash on the rail but then you cant forkload your slabs onto the bed unless using a set of slings.  

If the cam followers rode on turned up flat stock there wouldnt be too much of a shelf to sweep off atleast, a simple track brush should suffice.  Think of a flatbed rub rail, not much bark laying ontop of it.

I had to smile at the first post and the minitech .I used tons of it at work, it's kind of like high tech unistrut .Problem is there are so many making it there is no standardization at this time .It's pretty much industrial stuff ,easy fast fabrication but the average DIY person couldn't afford to buy it .
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 08, 2019, 08:34:30 PM
so true. If it was not thrown away I would not have it. But it does work extremely well. it still surprises me for the cost of that vs the cost of a welder that more benches are not just welded 1" steel.

Its not like they ever reuse it if they need to modify the bench. be cheaper to throw away 3 fabricated benches than build 1 out of minitec.
Title: Re: Router sled for surfacing slabs
Post by: Al_Smith on February 09, 2019, 07:16:57 AM
Because automotive assembly lines change so much it was a viable option to use the stuff .It was ordered in 20 foot lengths or rather what ever that was in metric by the multiple bundles .I likened the stuff as saying it was an industrial version of the old erector sets of years ago replaced by Legos .
The stuff I assume was the brain child of some European design because I first saw it on German made machinery .
The types of fasteners are almost unlimited,angle braces and so forth .It doesn't do you much good to have the basic channel without the fasteners .In that aspect it's about like unistrut .The cost savings are basically made up due to the fact of ease and speed of assembly as opposed to welded steel which requires a higher skill set .
Title: Re: Router sled for surfacing slabs
Post by: mike_belben on February 09, 2019, 08:15:42 AM
S&W stocked unistrut, 80/20 and creform.  There was way too much workload for the welders and a simple bench may take a week to have made.  The cut and clamp systems only took.a bandsaw and some basic tools.  The welder got $20+ pet hour and the temp making creform carts probably $11.  It was chinsy throw away chinese garbage but assembly lines change weekly so who cares, it got tossed all the time.

I built a wood/plywood sled that does about 24" wide stuff using my big 3.5HP Porter Cable router.  It works OK but the friction wears you out when doing longer slabs.   Then I took some of my milling profit and bought a wide prebuilt all aluminum one what has almost now friction as it used wheels.

thanks dr buck. I been wanting to know how to do epoxy for a long time. that was great. the router sled is nice to. 

Now I may be tempted to try this. Wonder what it would be like adding led's to the epoxy coat? bet it could look pretty amazing.
Title: Re: Router sled for surfacing slabs
Post by: Al_Smith on February 09, 2019, 11:45:37 AM
Creform is another option .Again it wasn't heavy duty stuff but it worked and was fast .Fact I've used the discarded roller casters on my tool boxes which has worked out very well and the best part they were free .
After 29 years I amassed  great quantity of discarded Kennedy tool boxes .It took me at least 6 trips using a Ford Ranger to haul them out .Some of them must have had 500 pounds of stuff in them and gave the little truck quite a load .
As for the subject I use a portable power planner which does a pretty fair job .Going cross grain it does get a little noisy though but it works for a job seldom done on the stuff I do .
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 09, 2019, 01:19:41 PM
Had to look up creform. yup we use that to. I almost got a bunch of the rollers but they emptied the bin just before I got there. TO bad I kept thinking those would be great at the sawmill for moving slabs.

My latest rendition of the router sled uses Bishop-Wisecarver grooved wheel/bearings. This setup will have dust collection, 5 1/2 foot width and 40 foot length, more than enough for the average table top. It will be up and running in a few weeks and I will post pics.

Cool,,,I've owned a lot of 460's in various vehicles.Years ago I would buy rich peoples used Lincolns, detail them and then  resell the shiny cars  at a profit .These wheels are tiny because I don't have the room.I picked them because they will ride on angle iron or barstock. In the picture notice the carriage is steel tube with barstock pop-riveted to the side , a simple copy of the Lucas mill side rails with materials I had on hand.The ends are bolted on and slightly adjustable to take out any welding distortion.The assembly came out pretty flat........

I see adjustable holes. that mean the cross slide will be adjustable? how are you going to do up and down? Just use the router?

I would love to do something other than the router since mine is a royal pain to adjust.

I've got a 3.5 HP plunge router .Ryobi which is just like Craftsman and Freud except for the color of the handle .That thing scares me to death and I will not run it freehand .That thing could gnaw your hand off in a millisecond so it's only used table mounted .Were I to build something like this I would prefer it to be very sturdy made using a tool like this with that much power .
Using a 3" panel raiser I don't take full depth but do it in multiple passes .That thing with that large of a tool could kick a piece of oak out with such force it could really hurt a person .I've got all my fingers and both eyes and would prefer to keep it that way .

Got some goodies in the mail last night 8) I'll add more pictures when I get the router box portion made. I ended up going with a 1 1/4" straight bit, we will see how it goes but with a 1 3/4 hp router I didn't want it to be overloaded. The rails are 8' long so that should get us in the neighborhood of 7'-6" length in one set-up.

I bought a 2" and 2 1/4" straight 2 flute carbide cutter. I think my router is a 1hp. it works good I have taken a heavy 1/16" off in one pass with no problem.

I got my cam followers I ordered yesterday. Should be getting my linear bearings on friday. Of course those parts are supposed to be for the mill but if they do not work there they will work great for router sled.

that is a cool idea, could flatten a slab anywhere.  Not the same rpms but with a big cutter the outside edge is moving pretty fast.  I think routers turn about 15 to 22 thousand rpms.   :)  smiley about 29 rpms

LUCAS MILL - Planing & Sanding Discs - YouTube (https://www.youtube.com/watch?time_continue=37&v=aZ-Ubkwsl4Y)

I looked on the Lucas web site but I did not find the diameter of the disc, there are two sizes for different size mills.

The smaller disc is for the 6" mill that uses a 16 or 18 hp, the larger disc goes on the 30hp mill

From the planer disc instructions

"
  • VERTICAL DEPTH - Set the disc to the desired height. Remove a maximum of 5mm in the
    first pass and 1 2mm thereafter until desired finish is achieved.
  • HORIZONTAL ACTION - Move the disc across 50 60mm (2 2 1/2) with each pass. The
    more you increase the width of cut, the more grain tear you will experience."

    The grain tear out comment makes sense because when cutting length wise on the slab the wider the surface you cut with the disc the more you are cutting across grain.

    So the next logical step is to use a spiral planer head. :laugh:
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 13, 2019, 10:32:52 AM
but that is 900+ for a spiral head. If I am going to spend that kind of money I would just buy a nice planer. Problem is i want 25" width.

The bargain seems to be the 12" for a Delta planer $426.00 https://shelixheads.com/SHELIX-heads_for_Planers/SHELIX_Heads_for_Planers_by_DELTA (https://shelixheads.com/SHELIX-heads_for_Planers/SHELIX_Heads_for_Planers_by_DELTA) not sure of the diameter of the planer head so the issue may be getting the bearings and drive pulley set up so they don't interfere with multi passes on a wide plank.

Another more costly option could be spiral cutters for shapers and molders
https://shelixheads.com/SHELIX-heads_for_Shapers_and_Moulders/shelix_for_shapers_straight_bore_112 (https://shelixheads.com/SHELIX-heads_for_Shapers_and_Moulders/shelix_for_shapers_straight_bore_112), they are not 12" but wider than you can cut with a router bit.

A guys aloud to dream, right? :D

So true. I was actually thinking of building my own super wide planer. But for just the shelix heads it made the cost a little high for me to swallow. Maybe one day. But till then a router sled will work perfectly.

Yep, if you had a lot to do or had lots of opportunity to flatten slabs for hire it might be worth it otherwise the router is probably the way to go.

Now if there was a way to make the router travel back and forth and advance in the cut on it"s own.......perhaps up one side of the slab and down the other.....

I'm always dreaming.

Mike maybe you can lay all the slabs in the yard and mount the cutter to a mowing deck, can use pulley to get rpms.  then just drive over all the slabs.  Sadly someone is bound to try this.  lol.  turned your dream into a nightmare.

Setting up limit switches and stepper motors to automate the process would be pretty easy and relatively inexpensive.

could set the slab then place your rails and have clip on limit switches that clip to the rails then simple program for offset and hit run. It will run until it contacts a limit switch shutting it off.

Depending on what happens with all this I am working on it may be something worth doing. But in the grand scheme of things how often will I need to surface anything over 12". a dewalt or porter cable 13" planer from any of the big box stores is about $600. Would be a worthwhile investment for my level or surfacing.

Or I sell surfacing services? Dunno, lots of options. Maybe that is a good idea.

tule peak is that a 3" cutter? I like the bristle idea.

Could always make a chain drive series of spindles or even gear drive that runs 4 2" router bits. Aligning would be a PITA but could be done pretty easily. be setup just like gang drills are.

I got it all put together this weekend and did a test run on a slab 8) overall I am pretty happy with how it works, one thing I will be changing is adding extensions to get the 80/20 bearings further apart from each other. Currently the bearings are mounted about 6" from each other which made the sled bind every once in awhile. making them about 12" apart should remedy this problem. The main rails are 96" long and should be able to process 7' material easily and about 45" wide. We also added the option to make it narrower in 6" steps as well (set at the middle set of holes in the picture below.

(http://forestryforum.com/gallery/albums/userpics/49164/IMG_20190217_130313530.jpg?easyrotate_cache=1550493847)
 

You can see the bolts in this picture where the bearings are mounted to the box. I need to space them out more to make it less temperamental.

(http://forestryforum.com/gallery/albums/userpics/49164/IMG_20190217_130321040.jpg?easyrotate_cache=1550493846)
 

And here's a few picture of the slab. Since it was a tree crotch with 3 branches it moved a lot during drying so I took 2 passes at 1/4" each. to get one side flat. We shimmed the slab and I shot screws through the sides that I know will get removed during further processing.

Here's pictures of what I got done yesterday, one side flat.

In the last picture you can see I tested going back and forth across the grain. I much preferred to go with the length of the slab. It definitely doesn't leave a perfect surface but everything should clean up nicely with 80 grit.
Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 18, 2019, 09:50:11 AM
Looks good. you are 100% correct about the dust and the mess. I also found going with the grain was much preferred. It left a smoother finish and was less work. With the setup I have played with going with the grain left me less to clean up as well. What I found works best for me was to make a full pass in the normal cut direction then shift the router towards the smooth side about a 1/4" then return to beginning making a climb cut then move to the uncut side and make your next path. this left me very little uneven if any. I will have to post come pictures of my latest Frankenstein creation. I have one more slab I need to smooth for my drill index part of my machining tools cabinet build.

Post by: DWyatt on February 18, 2019, 10:05:52 AM
One thing I will note is that the D-Handle on the router is a big nuisance here's a picture dad sent me that he took while I was running the router. One hand on the body of the router, one hand on the other side of the sled. I tried to run it with a lighter grip on the router, NOT advised. I was taking nearly 1" wide cuts x 1/4" deep in both directions. While the surface isn't perfect, its flat and sandable.

I had to remove the handles from my router to fit in my track. 
Title: Re: Router sled for surfacing slabs
Post by: doc henderson on February 18, 2019, 10:19:55 AM
I use my big porter cable plunge router.  You could also make a base for the router that is a sled inside the sled, but if every thing gets thicker, you have to extend the bit further and it becomes less stable.  I still only cut in one direction so the cut is pulling router in.  If you wanted to could move to each end and cut in both directions, but easier in my opinion to just pull it back across not cutting. If you can lock the cross sled in position for a cut, there is less to hold.  If the sides of you cross sled were shorter it would make your handle work better.  but you may need the c-channel effect to support weight going across a wide slab.  the bottom of my cross sled is only 3/8th inch thick so I can extend down a ways.  My plunge router has steps to drop by about 1/4 inch at a time.

It looks like you could set it up on a lower bench or the ground.  That will be good for thicker, wider, longer stuff so you can reach all the way across and still control the router.  My project was end grain so direction made no difference
Title: Re: Router sled for surfacing slabs
Post by: doc henderson on February 18, 2019, 10:35:14 AM
If you will be doing slabs with the grain and can surface the long way, I would make a router base that can lock in place, then you just can push the whole sled down the track.  keep the router base and sled base thin so the shank of the huge router bit does not get too much stress. i.e. the thicker all of the bases are, the further you have to extend the bit and or have less of the shank in the collet.
Title: Re: Router sled for surfacing slabs
Post by: doc henderson on February 18, 2019, 10:43:25 AM
maybe you could rig double screws or cables to pull your sled equally on each side.  this would decrease binding from torqueing the sled inside the rails and could operate with one hand and drink coffee with the other!!!   smiley_beertoast  .  sorry could not find a cup of coffee.  We will have you thinking like an old man soon enough. 8) Might even want a remote on/off switch to start and stop, esp. if the stuff hit the fan.

Post by: mike_belben on February 18, 2019, 10:44:36 AM
I dont know if metal work carries over at all here but if i was mowing a quarter inch off an aluminum billet and wanted it fairly clean in a single pass it would be a pretty stout two flute end mill and only climb milling.. In the case of wood id be trying to climb with the grain.  If its browning the wood the feed rate is too slow. If its tearing and peeling the wood grain then spindle speed is probably two slow gi en a sharp endmill.  Should be big crescent chips flying off with no heat coloring.

  Ive only milled woodblocks a few times in the bridgeport (which is what a router sled is sort of trying to mimic except in flying gantry format rather than fixed head cutter) but that feedrate and chip output is what youre looking for when doing it on a vertical mill.
Title: Re: Router sled for surfacing slabs

Post by: DWyatt on February 19, 2019, 11:04:06 AM
Yours is much smoother than the one I made. :o Some of which may be a function of the depth of cut, but I definitely think the actual linear bearings you're using are the ticket. A couple questions.What size of bit are you using and with what router size? What is the base that your router is on that fits in the groove of the extruded pieces? What is your depth of cut your taking and how wide are you in between the rails?

Title: Re: Router sled for surfacing slabs
Post by: Crusarius on February 19, 2019, 11:15:55 AM
That slab is about 14" wide I think I was 18" between the linear bearings. The plate on the router just happened to be the plate for my router table. It fit perfectly in the grooves. 

The bit is either a 2" or 2 1/4" 1/2" shank carbide 2 flute cutter. I don't remember which one I had in it. 

At the deepest cut I was probably taking 1/16" off. I have done quite a bit more than that but (around 1/4" maybe?) was trying to keep that slab as thick as I could for the project I am using it for.

I think the router is a 1hp. I wasn't even using the big porter cable I have.

What I do have sometimes is the router chatters because the plate is not tight in the grooves. But my technique / pattern that I use seems to take care of any issues. The slabs come out smooth enough I could get away without sanding but usually just do a quick 80 grit rub down on my DA.

what about cellular service? which cell provider offers service in your area? do they offer a plan for hot spotting? we were working a fire in napa valley 2 yrs ago and the fire had burned the at&t towers down, but verizon towers were up and running. luckily, i buy my phone out right from apple, and always get the unlocked phones. i went to verizon and after a few of arguing with the guy, he learned something new, that an unlocked, using at&t would also run a verizon sim card. i purchased a 10 gb data plan for around $60 a month, which lasted me over a month, but bc i didn't reload the plan, i lost 3 gb of data usage. basically what I'm saying is, see if a cell provider has a plan that you can buy a data plan, and hotspot to your computer and use the cell service to upload.

Charles, great idea. but the cell service is worse than the DSL. I have verizon, it is the only one that works there. and the service is spotty at best. They continue to "upgrade" the infrastructure around me. It seems that everytime they "upgrade" something my service gets worse. I am pretty sure its a planned obsolescence program...

I feel all your pain with the internet service, we have a Verizon hot spot. It's our only option other than some kind of satellite service and I know better than to ever try that. I listened to Dad complain about the service and Mom complain about the bill for too long :D

On a different note, I surfaced the other side of the slab yesterday evening. I had to take about 5/8" off to get it flat. I did so in 3 passed (1/4", 1/4", 1/8") I used the method Crusarius talked about, taking a cut then backing off ~1/4" on the return. Much nicer surface! Now after spending some personal time with this unit, I would never consider it a primary tool in the shop but it will definitely be a nice one to have in the arsenal.

I had a Verizon hotspot device and wasn't happy with it so swapped it in for a Mifi which replaces a landline with cell. It got a much better signal than the hotspot . I now have Spectrum internet but kept the Mifis because I can put them anywhere with power and connect a surveillance system and access the cameras on the internet. Verizon seemed like they didn't want to push the Mifis but they were much better than the hotspot.

That is not sanded at all, I blew the dust off and snapped a picture. It is white oak. Cut about a year ago and dried in the kiln about a month ago. The areas where the branches are "braided" together was Hard! The 1 3/4 hp router didn't like taking 1/4" bites at 3/4" wide through those parts.

Are you running that Amana surfacing bit on a variable speed router? I looked it up and they say 18,000 max RPMs and the router I have is running at 27,500 RPM. I'm not sure of the implications if you run a bit like that too fast other than my mind tells me it could be bad.
Title: Re: Router sled for surfacing slabs

typically if you spin them to fast they have a tendency to come apart. It could be very bad :)

I agree, it may also be hard on your router.  may bend or break the shaft.  may just make more heat.  I have a big PC plunge with variable speed, but they make pedal switches that are also variable speed.  at that diameter, the cutters are traveling fast on the outer edge.  looks great.

I don't think that is going to be a problem since it is a router bit. its reasonably high quality for the price I paid.

Besides I am member of the VFD I get free rides :)

Well a variable frequency drive beats calling the volunteer fire department in this case.  If were comparing VFDs   ;D

My plan is to use a 9 inch insert planner blade on the swingblade/slabber mill.  Will need to adjust the blade offset so the blade is flat.  35 hp should make quick work of the slabs.  I have a garage and barn full of slabs.  Then use the sanding pad to finish the wood off.

That would definitely be pretty slick. And make short work of it. It doesn't really take all that long with my setup but could definitely be faster.
