A sewing machine pedal is a rheostat (variable resistor) used to vary
the speed of a small (1/4 hp or less for a "home" type sewing machine)
universal motor. Such a motor and control would be ok for a lightly
loaded banding wheel, but would tend to bog down when heavily loaded,
such as when centering clay. I don't know if the ratio would be right,
but a friction-drive, rubber-tired bobbin winding wheel attached to the
sewing machine motor shaft, driving the rim of a banding wheel might br ok.
Just wondering out loud,

Hello,
I'm looking for an old foot pedal from a wheel to use for making an electric
banding wheel. I have an old wheel head in fair condition and an extra 1/3
hp motor, so i am going to try to put them together for use in a spray booth
and i just need the pedal now. If anyone has any ideas on where to get one
without a big investement i would appreciate to hear it. Thanks

In most cases, you will need a permanent magnet or shunt-wound DC motor,
rather than the more common AC motor.
Just a caution,
Roger

What about using a sewing machine pedal?

Roger -
For an electric banding wheel, a sewing machine motor and foot control work
great. If you go to a good industrial supplier or truck parts supplier you
can get a very small but very stout rubber O-ring which will fit snugly over
the drive pulley on the motor, making a friction drive surface to operate
against the outer vertical edge of the banding wheel.
You are right about the sewing machine foot controls. They are only for use
on very small motors, they deliver maximum power only at maximum RPMs, and
as the speed decreases, so does the power. As you know, the whole reason
that wheel manufacturers use DC motors with electronic speed controls is
that they maintain high torque at all speeds.
Best wishes -
