Hi and welcome Dan. I recently built a motorised bead roller from some Tom Verity plans. I was able to do all of the machining in house, but quite a bit of it can be done without access to a mill if need be. There is a build thread here.

So far I'm very pleased with it, but I'm pretty new to this.
Lots of other simpler builds on here too.
