Some great tips, you guys, for sure, thanks.  Brucer, I laughed when I read your post, because when I tried the double clutch thing a few days ago, that's exactly what happened, I rolled to a stop before I knew it.  So you guys who did this for real, what is the advantage of clutchless shifting?  Better control, faster, easier, etc?

Piney, I would consider that an "IMPORTANT SAFETY TIP" so thanks for that.  Mine has an electric actuator, but either way I've got a lot to learn about the old girl.

Today, I bought a couple $50 used steer tires as one of mine is a retread that I just noticed was starting to separate.  I believe its illegal to run them on the fronts, anyway.  I also splurged and bought 8 brand new spark plugs, and a new air filter, as the old one was black with mold.

After I got all the luxury items installed except the tires, I took it out for a spin on our gravel road and tried a little clutch less shifting.  Lets just say, I've got a little practicing to do.

I spent many a summer driving a '73 F-600 with a 4spd tranny and 2spd rear end from the age of 12 on up. my job to keep it under the combine auger to unload on the fly. Once ya get the hang of those gears you can float em in your sleep.  ;D

 After you get use to the gears. Try going down a hill in gear, turn your key off for a few seconds then turn it  back on. Then go back and pick up your muffler out of the road, if it is still worth having. You'll get a bang out of it!

Double clutching is simply a way to match the speed of the gears that are about to mesh. You can do it shifting up or down, but it isn't necessary with "synchronized" gear sets. A lot of manual transmissions in the 50's and 60's didn't have synchronized 1st gear or reverse gear.

Don't try the clutchless shifting until you've mastered double clutching.

I learned to drive an 8000 lb homemade forklift when I was 12. Four speeds forward, four speeds in reverse, none of the gears synchronized. You had to pump the brake pedal 8 times before the brakes would grab. That's how I learned to double clutch. (passing my drivers test 4 years later was a breeze ;D).

The only reason I did clutchless shifting was to show off (when I was in my teens).

I did use it on one occasion when our next door neighbour was trying to get his car to the repair shop after the clutch linkage broke. I had to start the car in first gear and kill the engine at the stop lights. I probably wrecked his starter but was pleased as anything.

Nice upgrade on the sawdust collection  8)

I found a '69 dump that had been a beer truck in its first go round.  Run the blower exhaust through the little door in the tailgate.  I can fill the bed in a day if I am jointing/planing all day.  The bed in my truck had been hammered by hauling scrap stone from the quarries so it is scalloped and has a couple small holes.  When the sawdust is wet it can be a pain to dump.  Still better than the small wagon I started with.

Have fun and stay safe  :)

It finally happened, my old dump truck finally gave up on me.  The brakes didn't work, the head gasket was spraying water (I'm pretty sure it's not supposed to do that), the tires were leaking, the throwout bearing on the clutch was squealing, the fuel pump was dripping gas onto the ground and it needed new windshield wipers.  :D. Other than that, it was runnng fine. 
Here's a picture I took the other evening, a little white smoke never hurt anything.  So I called a man and she's gone.




I am experimenting with a self dumping hopper for sawdust collection.  I figure it's like a dump truck, just no mechanical stuff to break down. So first thing I did was plop it on the ground and blow the sawdust in it.  With the big Timberking blower, the sawdust was blown in, then immediately blown out.  No dice.

So I remember I had an old Grizzly dust collector in the shed and went and got the centrifuge part and mounted it on a piece of plywood and tried that.  I put the whole contraption on an old flatbed trailer, and it worked OK but still had a lot of sawdust blowing out, spraying everywhere.  To much airflow from the blower.  Nice thing is that I'm using wood planks to mock things up, so I can change configuration fairly quickly.
 



Well, on to plan D or F or whatever.  I moved the bin to the ground, and slid the centrifuge to the other side in the bin, and covered all the open holes by moving some wood around in it.  Jammed an old tarp to into some holes, the slid one of the top boards open a little to provide a vent on the other end of the bin.  It actually started working.  I had an old bag that was open on the bottom and tied it to the top of the centrifuge, and I started capturing about 95% of the sawdust.  Eureka.  About the only stuff coming out was the very fine dust through the dust bag.





So I'll keep tweaking it, and when and if I get it like I want, I'll weld up a hinged bin top out of metal and steel plate instead of wooden planks.

I'm still not sure this is the best way, though, seems if I make a tripod and hang the centrifuge under it, the dust should just spin out and fall in to the bin.  Then I wouldn't have to unhook the hose every time I need to empty the bin. 

Or maybe I can try...., :D

Any suggestions are welcome.

YH -

Does your cyclone have an outlet on the top and a baffle inside?  I ask because I am installing one for a customer who is finishing up a pretty high end wood shop right now.  The dust collector is powered by a 15hp 3 phase motor and has a 16" main trunk so she moves a lot of air, and the cyclone is set up like I described above.  This unit is on a pedestal, the outlet being about 2' above the top of the collection bin with a large air and water deflector on the very top that looks like a giant exhaust stack from a semi.  We made a very simple removable box to go between the bottom of the cyclone and the bin top to keep the wind and such from blowing any around as this place needs to stay very clean.  The cyclone is about 7' tall itself, by the time the dust reaches the bottom of the unit it just drops into the bin as the air blows out of the exhaust stack.  I will see if I can get a photo of it for you.

Yes, outlet air goes out the top and the sawdust spins around and drops through the bottom.  Its a pretty simple design, it has a tangential inlet and it has a baffle ring or a ledge of metal that is a couple inches from the top edge to keep the dust from rising out of the top.

I'd like to see a photo of your cyclone.

Here is the big brother to it that we based the install on. This one is about twice the size. A dumpster bin sits under the whole thing and it really does not loose anything as the dust has plenty of time to loose any speed falling through the square unit under the cyclone.

That's what I would like to get to, park the bin under the cyclone and empty when full.  So, is the square unit under the cyclone a necessity of would it work without it?  I wonder where I could buy a cyclone instead of having to build it

Basically that is a chamber that gives the dust time to slow down and free fall into the collection bin rather than still have velocity to it.  On the one we are finishing up that box became about 2' tall as this blower is pushing about 1/3rd the volume of the one in the photo.  I seem to remember you saying you have a blower that is about the size of the one I have at my place - 5hp?  So it would not need a giant unit. 

I just looked at e-bay and found a number of used ones, $1,500 - $2,500 some come with the blower, motor, and all for that price.  One thing to keep in mind - with setups like this you can get material bridging in the unit so sometimes you need to put a Vibco vibrating motor on it to knock the bridges down.

I'm a bit late on this one Yellowhammer but i would have ditched the truck save the dump and frame. You could box the frame add a hitch and run it with your remotes from your tractor.

 I think that model truck should have synchromesh  tranny but most likely shot due to past abuse, a synchromesh tranny is harder to double clutch without grinding than one without synchro's.  Steve

A cyclone separator shouldn't need that lower box under it. I've worked in a couple of shops where we were running blowers set up like Southside's pic and had grain side dump trucks with a plywood top under just the cyclone. We had a canvas tube from the bottom of the cyclone down through a hole in the lid of the truck. From Dave Gingery's "How to Design and Build Centrifugal Fans for the Home Shop" he also shows how to build a cyclone. There are some critical dimensions he mentions. The main body of the cyclone should be 4x the inlet dia, The top outlet is 2x the inlet. The lower cone section is as tall as the main body diameter. The rectangular tangent inlet is the same cross sectional area as the inlet pipe. The lower outlet dia is not critical but needs to be large enough to avoid bridging. There is nothing inside, the ones I've been around are hollow. The dust spins around the outside, loses velocity and drops out the bottom into the dump, the clean air at reduced speed and pressure goes out the top.

I'm a bit late on this one Yellowhammer but i would have ditched the truck save the dump and frame. You could box the frame add a hitch and run it with your remotes from your tractor.
I didn't think of that, but I got an offer I couldn't refuse on the truck.  The deal was that if the engine was running and it was generally in one piece, they would actually pay me money for it.   :D.

If it wasn't running, or in several pieces (the guy noticed the frame had a wee bit of a crack in it, where someone else's decades old poorly welded splice plate had broken loose and was causing a little camel back sag) I would have to pay them money to haul it off.  :D

So to quote what Martha told the guy, "Deal!"

Don P, good info.  I sure would like to go to a setup where I'm not spraying or leaking sawdust in the grand.  The dump truck worked a lot better than the original trailer, but now, I'd like to get to a cleaner, better system.

I can't believe you got rid of your dump truck because you didn't want to change the windshield wipers!! :D :D

Is your main 6" dia?  If it is, for $239, buy a Super Dust Deputy XL from Oneida and put it on the end of your pipe to make a quick set up like Southside posted.  It would be cheap and quick.  Keep it as high as possible and run a pipe down from the bottom to your bin, that will give more time and distance for the chips to slow down while hopefully most of the air will do out the top.

If you wanted a metal unit, Oneida makes and sells them as well, looks like they start around $900.
