Bowl Sander

This is a bowl sander for a wooden lathe. It's based on the design from this video: https://www.youtube.com/watch?v=myBwALrpYeM&t=6s

It's made to accept an M8 bolt and Abec 3 or Abec 5 bearings (the Abec 5's fit real tight, the 3's press in real easy; the 3 is my preference).

I made the handle from wood.

The picture attached of the actual thing has ridges on the face of the sander portion. That was an earlier version where I thought that more surface area would be better for gluing, but I like the flat face better.
