.SPLINTERS!

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

Just don't let it pinch you.

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.
