Glenn, since you're wiring in a new on/off switch, etc., take the time to build a simple guard or cover for the belt, too. You can do it with scraps of plywood, and it shouldn't be hard to figure out a way to mount it. It'll keep you and your shop dog's tail a lot safer.

Excellent idea.

Update. I got back from my long business trip to find my motor was repaired. Needed to be cleaned, and the bearings were replaced.
It's pretty common for open motors like that to build up dust and gunk in the start switch, which will keep them from starting up. ("needed cleaning"...)
I had a similar problem with an old motor. Once I cleaned out the gunk, the bearings had enough slop that the armature(?) was touching the field windings (?stator?), so it needed new bearings as well.
You're lucky to have a motor shop nearby - another disappearing thing with the 'throwaway society' - only bigger industrial motors are 'worth fixin' for many people...
When you're building your belt cover, you could consider enclosing the motor as well. If you have air in the shop it's a good idea to blow the dust out of the motor from time to time. Also, avoid over-oiling if the motor has sleeve bearings- the extra oil attracts sawdust.
