Here is my latest banjo uke. I unfortunately don't have a lathe yet, so I "turn" the rims on a pattern sander in the drill press.
One day I will get a lathe, hopefully.

Yes, I've made hundreds of block banjo rims. I sold them on The Banjo Hangout for about ten years. I recently retired from making rims and building guitars. I sold my custom made rim lathe and bought a Laguna Revo 18 inch to make bowls and boxes. I'll post some photos of a few rims after I figure out how to post them.
