I have split a bunch of 34" or so dead red elm, assorted oak and cherry. Even with a 10" wedge on my splitter, You only get a partial split just on the bottom. Then the monster wood wants to fall on the ground and in most cases it does what ever it wants to. Then wrestle it back on the lift and pop a different side. Eventually you can get it. After 50 cords of that big stuff, I now try to stick with 24" if possible. I was reading the early part of this build and I must have gotten lucky building my lift. I added a spool valve via power beyond to run the lift cyll. Then I just picked my pivot area and built the lift. Then when the cyll. was installed I just pulled the ram out and drew a line where it would hook to the lift at slightly higher than level. Worked so well I had to laugh. Lifts anything I can roll.
