I built this before I was married, 33 years ago from a bunch of junk. I'm waiting for it to break, I've gotten a little older & wiser over the years and a better welder with better tools, and a new build would be fun. The beam is a 8" 18# regular house beam. Not much, and she'll flex on the nasty stuff but still hanging in ther after all those years. I modeled it after a Vermeer that I saw hooked to a truck in a parking lot. Being young & broke?…... . It will go vertical, but I rarely lift it up, maybe once a year if I'm into some big stuff.
The 2 "features" that I will repeat are the tool box, and the knee operated valve. I would also make it horiz. only, and keep the wedge moving. My wood waries and I'm fussy about my split size and don't think I'd be happy with a 4 way. Therefore I don't mind splitting several times. With the wedge moving, your wood stays right in front of you for re- splitting instead of chasing it back off the wedge in a more normal horiz splitter. It also could be that I've been using this splitter soo long that i don't know another way!:laughing:
