Though, this isn't specifically about "Home Repair" it is an item in the
home.

I made a project for the wife which required the use of a sewing machine
motor (but not the sewing machine) which has the speed control foot pedal. I
want to remove the foot pedal and connect a dial speed controller,
preferably one with variable speeds, as opposed to a 3-speed type. I tried a
ceiling fan speed control which does contain the 3 speeds of high, medium
and low, and it's not what I want. For starters, low is obviously too low
since the motor only hums, medium appears to be OK speed wise but high is
too fast. I want to provide the wife the option of variable speeds.
Therefore, the big question is, doesn't anyone know if and/or what type of
speed control I can connect with the motor?

BTW, if it helps, according to the label on the motor, it's a 110v, 150watt
and 1.3 amps.

Thank you
