1M21 and everyone: Thank you for the responses! And Great pictures. I was thinking that maybe the web part (the top and bottom flat part) was a bit thin, maybe 3/8" or so, but then there should not be too much force on the "pusher" on the end of the cylinder, so I hope it will be ok.
I have looked at and studied the timberwolf machines, and they are awesome. I see on all of them they reinforce the steel where the wedge is and where the cylinder sits, so I will do the same. I will also try to raise it up a bit off the ground. My axle now sits maybe 10" off the gound, and I'd prefer this was not a back breaker when using, and I was not spending all day on my hands and knees when I split. I plan on taking part of that steel, and welding that the the axle for a base, and then put the rest on top of that so it sits maybe 24 inches off the ground.
I'm going to have a log lift, it does not look too hard and only requires another cylinder and a bit more steel.
On the wedges you all have, can I ask how you make them? I've seen some high dollar ones that are 1" thick, but can I make my own out of 3/8" stock, or will they fall apart?
Regarding the pump etc, I am looking at a 4" cylinder, 9-11 HP honda, and a 22 or 28 GPM pump. I don't want this to take all day to cycle, and I get the impression many "real" splitters use 4" 3,000 psi cylinders and they work great. (with a 2" dia rod).
thanks again everyone.
