Spent most of last night working on finishing things up and fixing things on the splitter.
What happens to a log lift hinge pin when it gets in the way of the push block

:
Dang thing rotated
handle up ... and the block caught it.
Heated it up with the torch and straightened it out ... after I did the same for the log lift brackets. Drilled the pins as well, for some hitch pin clips.
Got about 1 1/2" trimmed off the log lift top, which should keep it out of the way of the push block when it's raised. Also capped the square tubes ... so they don't collect water.
The super-duper thread sealer turned out to be Permatex No. 2 (non-hardening) - which I already had - so I got the two problematic fittings between the valves pulled, cleaned up, coated with sealer, and reassembled.
Heated up the pipes on the table grate and bent them into position.
Got the valve cover for the engine pulled and found what was causing the leakage (bent around the bolt holes) ... still have to straighten that out and cut a new gasket.
