I just built this rotisserie and it is really great, with only two points of feedback/consideration:
1) I think the 36" pipes are too high, I think using 30" would be more prudent -- this is personal taste though.
2) Is there any way to really stabilize it? I find that is moves considerably when scrubbing the playfield by hand -- can't imagine with a sander or polisher. I wonder if shimming the bottom tees would do it? It's also possible I need to crank down on the thumb screws more with some pliers. It's just hand tight right now.
EDIT: I wonder if cranking down two ratchet straps across the 1/2" pipes as close to the tees as possible would do the trick? I'll try it when I get home!
