[ARC5] Bearings for DM-28 dynamotors

[D C _Mac_ Macdonald]

I have no idea what (if any) definition is "correct."  I have a set of some small Craftsman "punches": 1/16, 3/32, 1/8, and 3/16 inches in diameter.  They are uniform diameter until they taper up to a square head.  I call them drift punches, because they can be used not only to drive roll pins out (or in), but to center holes in nesting tubing to prepare for insertion of a machine screw for fastening the tubes together.  Larger ones are very handy for connecting tower sections such as Rohn 25, etc.
