I'll be working first on the 24" Mac, which is a scaled-down version of the bigger looms, not the portable "baby mac" (CP) model. It's in the worst shape of the three of them, but I want to start using it first.
I didn't know there were set screws on the treadle rod. I never heard of drift punches, but now I know. I'll use PB Blaster as the lube unless you have a suggestion for something better.
I've been avoiding work on this loom because of my knees, but I just realized I can plunk the whole thing on a big work table and won't have to kneel/sit on the floor. Might as well save the joints for the tieups to come!
