This is a jig my grandpa and I built to cut the radius on a heel. It utilizes a wheel covered in sandpaper attached to a hand crank. The wheel has three levels. The bottom one cuts the radius for the tension hoop, the middle one cuts the radius for the rim above the flange, and the top level cuts for below the flange. The neck sits in an angled sled, and the sled slides forward toward the wheel. It works very nicely. It'll work for any 1 piece flange banjo neck. If you need another neck angle, you can either shim the neck in the sled, or create a new sled. Theres no reason one couldnt rig this up with a motor, but I preferred to use hand power, since it's more controllable. I thought I'd share this with y'all, thinking I could help someone else out.

Nice contraption, and fairly easy to build.

However, it appears that the drum's shaft simply runs through a hole in the wooden structure. I'd suggest you use a bearing there, instead, to reduce wear and probable ovaling of the hole where that shaft spins. You've taken the time to build a very nice sturdy looking tool, and you don't want to wear it out too soon.

...and it fits on the kitchen table. I've worked off of the kitchen table a few times myself!

That's awesome! I had a similar thought when I build my jig but I didn't have the ability to make a drum that size.
