Default WTD: Old Delta 1/2hp Motor

If there is a 1/2" shaft coming out of one end that isn't used -
a shaft can be put over it - and set screwed on.

It doesn't attach to the bell or frame, just the shaft.

He was into audio - home made amps and needed one.

The double shaft allows for a flex shaft that Delta sold.
Dad had one from the 40's and sometime in the late 90's it
finally bit the dust. Internal flex shaft broke. It was used
to wire brush stuff or polish with a cloth buffer.

Are you saying that this was meant to be used with the toolmakers
grinder?

While the bump-out in the casting accommodates the double shaft motor,
there does not appear to be any way to hook up to the shaft. If you
put a flexible shaft on it, you'd have to drill a hole in the
casting. If you put a pulley on the shaft, you'd have to have the
driven pulley below it - and there doesn't appear to be a mount in the
casting for such an accessory.

Marty mentioned balanced motors. I'm not sure that these were
balanced. The literature mentions that the pulley and motor were
balanced as a unit - implying that the motor itself was not balanced
to begin with, and that it was corrected by using an out-of-balance
pulley. Maybe I'm assuming too much, though.
