Does anyone have ideas about building a positioner for welding round parts? Maybe some pictures of one you built? They're pretty expensive, I'd like to try to build my own if anyone has any tips or ideas or prints etc. Or if you know of one that sells for a reasonable price.

Are you looking for a "kit" or a "project"? If you need a kit, certiflat makes a kit for $400. Just add your cordless drill and perhaps a chuck. If I "needed" one, it would be that one, as it is "complete" and not dependent on whether you can find someone else's parts list at your local places.

You can always do a "project" that turns out to be more work, I know I sometimes do that, lol. But I wouldn't want to for a positioner.

HERE is a link to a build I did several years ago

Here's a link to the one I built a while back too.

Those build threads are fantastic! Thanks for sharing them LtBadd and Coldman!

I have a big old lathe. It turns 12 RPM. I'd like to figure out a way to slow it more for welding. As is it can be rotated slowly by a helper.

A small rubber wheel on a variable speed drill either directly in the drill or by shaft and bearings so that the wheel runs on the side of your lathe chuck.

I'm thinking something like that on the other end of the belt train. Now i'm using a 1725 motor through the gear train I can slow it to 12. I have 190 RPM drills I could substitute easily, but there would be no variable speed. It'd slow to 1.3 Rpm. I don't think that is slow enough.
