garbage truck pump on logsplitter

[LD1]

I guess I just have to ask WHY?

For starters, are you really splitting 48" long wood??? because average firewood is 18-22", so you are wasting over half the cylinders stroke right there:confused2:

And why the 7" cylinder. I have YET to find anything that out 4.5" and 27tons of corce wont split. and we do split ALOT of green elm.

And lastly, how efficent do you think running and keeping running is that 300 I6 going to be compaired to a smaller 11HP motor??

I have seen a lot of people attempt to "re-invent" the wheel as you are doing. And they think bigger is better. In this case, I think not. With the parts you are buying, valves, pump, cylinder, and motor....sounds like parts to build a full blown firewood processor, not just a run-of-the-mill splitter that honestly probabally wont out-work a $1000 unit bought from TSC.

It's obvious that this guy isn't out to split hairs. He's doing R&D for Paul Bunyan.

The answer might be that he is using what he has.

He really doesn't need to use the total stroke of the cyl. He could clamp or set the wedge at 24, 36, or 48 in. Just plug in the wedge at three locations on the beam with whatever wood he has acquired.

He just might want the largest beast around.

If he gets all the other stuff like valves, filters, pump,etc, he could revert to a smaller cyl at any time.

With everything set up, it will only produce about 56 tons of force , using 7 in cyl, 2.5 in rod, and 3000 psi.

 

[LD1]

The wedge is on the beam, NOT the cylinder so I dont know what you are saying by just "plugging" in the wedge @ 24, 36, and 48 inches??


And he may indeed want the biggest and most powerful splitter in the neighbor hood. More power to him.

My point is mearly that for the amount of $$$ wrapped up in this thing, you could go out and buy one that will be just as fast, and way more efficent.

With "biggest" and "baddest" also comes terms like "slow", "cumbersom", "inefficent", etc.

 

[J_J]

I agree. The wedge could be placed at three spots on the beam, movable, set to size.

Perhaps three locations to drop in the wedge.

Wait until he gets that wedge stuck! ONLY 56 tons?!?! :laughing:

Definitely have fun with that Splitzilla. I want to see film at 11:00.

Looking forward to more pictures

LD1- Because I CAN, because I don't have enough paying work right now, and I am bored? Because the pump and engine combo, 10 hp/16 gpm pump was way to slow, just under 1.5 min cycle time or there abouts. Because I wanted to hang a Ford blue oval on the front of my splitter for the longest time?

I got the cyl from the salvage yard up the road in trade for 1 ton of scrap sheet steel. I run pickup trucks in the local demolition derby, so I have 4, 300 I-6 Ford motors in running condition just sitting and looking for a use. My outdoor wood boiler has a 36" deep firebox. The beam that I had looked really stupid under the 4" cyl that was on it when I bought it for $700 from a retired Ironworker who made things with all of the scraps of steel he brought home. With the 4" cylinder that was on it, I couldn't just split 16" logs in the middle, I had to work around the outside. I have a 19"x19" door on my boiler, and just need to split the wood down enough to handle it easily. To get the power and speed I hope to have when done, I would have needed to buy a new 28 gpm 2 stage pump and a new 16 hp engine, at which point, I would have over $2000 invested, and still need new lines and a larger filter, etc. At this point, I only have $1,300 put into it, and don't see anything else needing to be bought other than to fill the gas tank. I am still waiting on my Hi flow return line filter, but I did have it running long enough to time the motor today. more pictures in a few days.

valve-$275
pump/coupling-$420
Cyl-$240 in scrap steel trade, and had it mounted before this revision, anyways
Lines/fittings-350
1 more 5 gal bucket of universal ATF-48.00
motor-free from a demolition derby truck
frame-original from splitter
almost new tires-free from another demolition derby vehicle

Hopefully sell the old engine, pump, lines and valve for about $500, to regain some of the cost involved.

$1,333.00 plus other small hardware store runs that I dont remember.

Only 56 ton? that'll be real nice, especially if I want to crush car rims to remove tires faster for scrap

Just don't let it pinch you.

And sandpaper won't work. At least it didn't for Pinocchio.

At 56 tons I doubt if it'll be a pinch, any appendages caught in the wrong place will be just like squeezing a zit :laughing:......Mike

Ok... I finished it for the most part, Still don't have my filter, I called, and they said tuesday. I still had to play with it a little. As you can see from the pictures, I split a 16" sugar maple down the center nicely. The best part, though, is the fact that I sheared one of those halves in half cross grain. 1/2 throttle, and it didn't even grunt. Even better, I haven't turned the releif on the valve up any, it is still set at the factory 2000 psi, I have another 1000 psi to go if I want.

So, it appears that I got everything that I was after in my splitter project, speed-5 seconds to full extension, and 3 seconds return at 3/4 throttle, no load. Makes for 8 second cycle time. And plenty of power to spare. And as for that "knotty crotch" I have been ribbed for saying, I found one in my pile, an apple tree stump that was cut this summer.

Don't know what the problem is, but it took me 20 mins to upload just one picture, and then I kept getting a message that internet explorer can't connect to the page when I tried to upload more.

The reason is that that is a huge picture.
Take a look at: http://www.tractorbynet.com/forums/photos/107314-photo-posting-how.html specifically the part about resizing pictures. If you resize the picture to 1024x768 (rather than 3071x2303) it should only take a few seconds to load on a high speed internet connection.

Just curious, what size oil reserve do you have?

 

[J_J]

Using 2000 psi, 2.5 is shaft, and 7 in bore. recomputed the tonnage at 38 tons, still a lot. I am guessing at shaft size.

 

[me0418840987]

Crazyal, unfortunately, it is only 21 gallons. That is the reason I installed such a large oil cooler from a concrete truck directly in front of the radiator and engine fan. If that doesn't seem to be enough, I will install another cooler, this one has a port to connect another to it. I don't want to change the resivoir, because a larger one will not fit without totally reworking the frame, and sourcing a wider axle.

JJ, To increase the pressure from the valve, I turn the screw under the cap clockwise, correct?

 

[J_J]

Yes, but I would tee a hyd gage to the IN port to set it correctly.

What is the shaft size, I was guessing above.

 

[me0418840987]

JJ, The shaft size is approximately 3.5".

I weighed it at the truck scale today, It weighs in at 3080 full of gas and hyd fluid. When I am totally done with it, It will therefore weigh something like 3400 lbs.

I am looking for a hood from a 9-2, or 8N ford. It doesn't have to be pretty, but not flattened from being run over by a truck, either. If anyone has something in WI, MN, or ILL, please PM me. Just can't see paying $350 for a new tractor hood for my splitter.

Using 2000 psi as the pressure limit, the splitter could push with a force of 38 tons.

Using 3000 psi as the pressure limit, the splitter could push with a force of 58 tons

What is the GPM's of the pump, and can it pump up to a pressure of 3000 psi.

New data.

At max pump pressure of 3625 psi, push force would be about 70 ton.
