Re: Rich's penholder[Spindle lock needed]

Rich,

Just a quick thought:

Get a piece of spring steel (Car feeler gauge about the right size,
and cheap) Drive a rivet through a punched hole (or use the hole
already there in the feeler gauge). Fasten it onto the spindle
housing so that the rivet "peg" is under the motor pulley. (I'd use
three 6-32 panhead screws, 2 on one side, 1 on the other, in a
triangle pattern. Means you don't have to drill/punch more holes in
the spring steel, and the Length is adjustable...)

Now use the rivet to "spot" the alum pulley for a matching drilled
hole. Which will engage the peg of the rivet to stop spindle
rotation. Remove the pulley and drill the hole(s). see the P.S.

The "bump" on the rivet will lift the feeler gauge enough to use a
small screwdriver or a fingernail to activate the setup. The spring
steel means it will release itself.

Should be fast, cheap, work well, and not offend visual
sensibilities :-)

P.S. If you were to pre-drill holes carefully in the pulley, it could
be an indexer too! Old delta wood lathes had such a system.
