I deciding on weather to build a splitter or buy one. I currently have a small probably 20 ton unit.
I'm looking for a faster, more powerful one that will run a four way wedge. I don't know much about hydraulics and line sizes.
I would like a valve that extends and returns by it self. Any info will be great.

A hydraulic valve that has a detent at both directions is pretty dangerous for a splitter because if you would get any body part caught you wouldn't be able to disengage the splitter! Most just have a detent on the return stroke. The next thing that I would suggest is at least a 5 inch ram. Of course you want to have a two stage pump.

I would upgrade what you have, Building the frame and hyd tank is the biggest part of the build. Go with a 5" cylinder and a pump that will give you the cycle time you want, when plumming it use 3/4 or 1" hose, as mentioned before a 2 stage pump will greatly reduce the cycle time while providing enough pressure to run a 4 way wedge. The auto down detent is a bad Idea. (and probably Illegal if osha found out)
 
lots and lots of autocycle splitters out there. can be made with a piece of pvc, 2 eyebolts, and a bungy cord.
go look at mine on youtube.com

only real safety issue on ANY splitter is don't put your hand ever between the log and the plate, or the log and the knife.

if you want to put your hand somewhere, put it on TOP of the log to hold it.

also, in the west 5 inch is way overkill.

4 inch is good to 30 inch rounds of fir with a decent knife, and i've used my 4 inch and 4 way for about 175 cords.
 
thanks for the information, my current splitter has a small oil tank so I'm not sure it will have enough capacity.
 
Responding to the idea of detent in both positions....

I've twice had the fingers of my gloves caught between the wood and moving wedge, Pulling my hand along with the wedge into the wood. (Fortunately sounds more drastic that it could have been)....the thing is, my wife, working the valve, is deaf. (Same goes for my right hand not knowing what the left is doing.)

So my screams of "STOP!" upon deaf ears, and eyes to which I couldn't sign to (hand having been trapped), made for quite a ride. She saw the expression in my face and stopped. Some blood blisters and a week off splitting had me good as new....BUT, what if my opposable-thumb was in the way and got sheared off because the ram couldn't be stopped in time...What if your spouse/child/neighbor/friend was at the controls with hearing protection on and didn't recognize your screams.... how will they feel 10 continuous years from now when your trying to open the envelope at your mailbox without your thumb.
 
auto splitting?

for what reason? to rush the job? run it safe and enjoy the time outside. a couple of seconds can't really mean that much in a hurried life.
 
Why would anyone have another person operate the control while splitting wood? This is just an accident waiting to happen.
 
NEVER put your hand on the ends of the firewood near the plate or knife.

ALWAYS hold the wood on top and bottom, leave top hand to hold the wood, bottom hand to run the lever.

split a couple of hundred cords for a living, and then we can discuss how much "FUN" it is to sit there and watch the ram cycle back and forth.

myself, i'd rather watch the split pile get bigger faster.
 
I hear people saying hold the wood with your hand. I can personally say, thats not always a good idea. As soon as the wood and wedge engage, my hands come back as far as my body. I might reach out and grab a piece that is ready to fall away, but I wont let my hands ride on the wood or be near it any longer.

I had a piece on there that was a lil tough and I could hear the machine bearing down and workin hard. The piece of wood suddenly popped and a chunk came flying off. Bent my thumb over backwards to the back of my hand and broke the lower thumb bone. It has made for a tough fall to get the rest of my wood done.

Just be careful no matter how you handle it.


Dang forgot any tips! If I could build one, I would think of the whole process and build the splitter around that. I have used several splitters now and looked at a bunch, and all have something unique that makes them work well or not. I'd have the trailer hitch in the front. You can leave a truck or quad hooked up to it for stability if you want. The wood would be pushed towards the back. When you get a pile and are still working, you can pull the splitter forward and continue working without having to pick up the pile. The engine should be away from where the split wood will be, so that pieces do not fall off and break things off. The filter and all hoses need to be postioned to that no wood can contact them. I 've busted 2 hoses and dented a filter with wood tossed or falling around. A log lift is nice, with a large enough cradle to hold a piece of wood bigger than what you think you will ever split. A work cradle to hold the piece you are splitting in place so it does not roll off if you want to keep your hands clear. A table on both sides of the splitting zone to work with on pieces that need to be fed through several times. Bending over to pick up pieces multiple times is a big slow down. Make the table out of pipes or somehow slotted, so that debris falls through and out of your way. The auto return is nice, the auto forward is bad idea as stated above. I'd build it high enough so I am not bending over all the time to work. Larger tires are not that much more than the cheapie ones, and make the end of the day that much better. Trailer lights, with protected lenses and wiring. Eventually your gonna want to go somewhere and its better to have it there than wishing it was. Cup holder for ice water? A sign that says "I cant hear you" when people walk up and try and have a conversation with you? Ahh you could do whatever you want if your gonna build it yourself.
