If anyone is interested, I am building a rotisserie. I was able to get pretty much all the tubing/material from the scrap pile at work. I think the only thing I had to buy is the hydraulic cylinders ($30 each at harbor freight). Here is the CAD model:
Here is the outer pivot, it was a loose fit, so I cut some sleeves from some 2" exhaust tubing, welded them in and bored the ID:
Here is the inner pivot piece with the groove cut in for the thrust bolt:
And here is my newest tool, a Dake 25 ton press that they were going to scrap at work. Got it for the scrap price, it just needed a new leather packing (and a good cleaning). I built the little press brake frame for it. Here it is bending the 1/8" thick steel C-channels, only took about 5 tons...
