I decided to remake my log splitter into a self propelled version so I wouldn't have my loader/winch tractor tied up. I have an 8hp Tecumseh and bought a two stage pump (fast until pressure builds and then slow for the high pressure need), made an adapter, fitted the engine with a new carb and 12V electric start.
   
Next step in my bumbling thought process was to make a complete new log splitter, reason being , my projects are so protracted at some point I'd desperately need the splitter while it was in mid-reassembly.
Once the new one is done I can sell the 3pt tractor splitter.
So here's a poor pic of the tank/cross member and wheels up on my best friend (110V electric forklift).
   
Here's a better shot (I hope) with fittings and filler neck.
   
So the new beam etc. has evolved to this.
       

The reason the "wedge" (chisel edge not yet cut) fits in the rectangular "socket"
   
Derives from a splitter build that had a hydraulically raised and lowered single/4 way wedge, you could select splitting in 2 pcs. or 4 just bay raising the wedge and it's cross wedge to the height req'd.
I decided to used changeable wedges that could be manually inserted into the rectangular "socket" because I might want to try a 6 or even 8 way split!
Here's a pic of machining one of the "slots" in the H beam (the far end is supported by "my best friend" and a glimpse of the socket I made from a 6" length of 6"sq. tubing sliced down to a .625" wide by 4.625" I.D. rectangular socket.
   
Next developments will be the log lifter, I'll post when progress is made. All welding will be done at the same time as I find my welds get better the longer period I'm welding.
