Thanks for the tip on the crud-thug!
It looks like snap on doesnt sell them anymore, and they infrequently pop up on eBay from time to time. After watching some videos, I think I'm hooked on it! TP tools does make a version that lists for ($200) half of what the snap on unit ($400) did, which I may look into. I have their blasting stuff for my powder coating, and it's some of the best I've used! A company that I've never had any experience with, MBX, makes a version that looks just like the snap on one as well.
It's expensive, but I see myself using this thing a LOT in the future!
Also, did you have any more pictures of your rotisserie? I'll be building my own, and am considering adding in 2 hydraulic rams for lifting, and making it adjustable to fit a variety of vehicles, mainly so I can sell it when I'm through with it
