Hey guys,

I would like to make and indexable / rotating table for my brother in law that he can use for welding. The type you clip your ground to and can turn it while you weld. Any ideas, suggestions? I have an idea, but i thought you might have a better one

Rob :)

Sparkman,

I will be following this thread. I have also been thinking about building something like that but don't think I need to re-invent the wheel.:)

I've been saving a used unit bearing and a Farber rotisserrie drive for making one.

The unit bearing has a good place for a sliding contact so the ground lead doesn't twist, but I'll probably just wrap around the hub, and let it unwind as it turns. A DIY slip ring for high current seems like a real challenge.

Two threads spring to mind and I think I found them via the search link above.

I'm sure I missed some other good ones but my recall is off at the moment.

I made one from ball transfers that I got cheap at an auction. Mcmaster-Carr has them here: http://www.mcmaster.com/#ball-transfers/=a1k0vg

I cut two rounds from 1/4" plate (can't remember the exact diameter) and installed the ball transfers on the bottom plate with short screws. A center bolt later and she spun like a top. I did use a thin sheet of plastic film on the bottom to avoid grounding through the transfers to the welding table.

So far so good.

Another option might be the cheap little cast wheel casters from Horrible freight. Just a thought.
