I need to make something like a mini rotisserie for working on my fenders. Does anyone have any good pictures of something like that I can get ideas from? thanks

 

I usually make them from plywood or other scraps...screw the fender to it through the mounting holes. Then attach the whole thing to a work table or bench.
If you need it to rotate, maybe attach it to an engine stand?

 

No wood, metal. I've seen them but it's been a few years and I need to get my head wrapped around it.

 

Tack weld both ends to one of those 8 lug wheels. Oh, and don't forget to block the wheels before you go inside for lunch. ...

 

Yeah, gotta pull the other wheel tomorrow to get the fender off. I'll be giving that slanted driveway a lot more respect.
On the fender jig, I think I'll take my spare engine stand, pull out the engine part and get a piece of pipe to slide in. Weld on some tabs to make arms to affix the fender in 4 places. That way I can rotate the fender like a rotisserie. These fenders are rally long so I might have to make a support for the free end. I'll post pictures if it works.
