The shaft diameter is 5/16", O-1 drill rod,
held between a 5/16" A3 collet and a live center. The wheel is about 5" from
the wide end (in the collet) mounted on a
threaded region, supported by a collar.

The drive rod is winding up.

Bore a 5/16 hole in a faceplate, and GLUE the disk to some blocks to make it
parallel to the faceplate. Put the blocks out near the edge to be machined. It
won't chatter that way because it's coupled to the large mass of the faceplate.



Yours,
