Opie,

I know this post is over a month old, but I couldn't help but reply. I too would LOVE to build a tumbler. And even started accumlting parts for one. Someone over at O.G. had plans for one using a rotissary motor and some round plywood blanks. Add to that some threaded rod, metal tub to fit over the rod and some misc wood, nuts and bolts to assemble the thing. The only part I was never able to figure out was on the non motorized side the author mentioned some sort of bering assembly. There was no pics or part numbers mention, so I've yet to put the thing together.

Perhaps together we could figure something out? Lemme know if yer interested, 'k?
