I have an old - well it was bought new in 35 by a friend :-)
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.

For the Toolmaker?
I put a half horse TEFC WEG (Brazilian) motor on mine. From what I've
read the surface finish isn't going to be perfect anyway, they say 20
microinches. It leaves a visible pattern in the ground surface that I
can break up and remove by cranking the wheel zig-zag.
Yup, for the toolmaker. Not looking for the "balanced" motor specifically,
but the old Delta motor that is 6" in diameter so it will fit under the
cast iron motor cover....
I know they aren't the best surface grinder in the world, but they it will
come in handy for my needs and it wasn't all that big. The price was right
at $250!

Thanks Jim!

The motor in mine looks to be an original Delta, although I don't
remember seeing any tags on it. Should be easy to ID, though, as it's
a double shaft motor.

Why they wanted a double shaft motor on the toolmakers grinder I can't
imagine. The front shaft has a guard or cover over it. It comes very
close to the cast motor cover. The motor cover looks like it was made
for that motor, though, as it has a bump out for the front shaft that
seems to be otherwise unnecessary.

Mine is a 120 volt 1725 RPM motor. The belt guard seems designed for
that speed - large motor pulleys driving smaller spindle pulleys to
achieve the correct wheel speeds.
