I have a little 30rpm motor that I use to turn fishing rods when

fast. Ideally it would be slower like 10 or 12 rpm. Is there any way I
can slow it down? Someone told me a rheostat but when I went to price
one at the local flea market it was $13 and had a foot pedal and I'm not
at all sure that would work. Any advice would be most welcome. Thank you
very much.


One obvious solution, that works without needing to know what kind of motor you have, is adding a belt drive and experimenting with pulley ratios until you get the speed you want. If you use a cone driving a rubber-tired wheel, you can even make it continuously variable. It may look crude compared to a variable-frequency oscillator driving an audio amp driving a synchronous motor, but you may already have the necessary parts lying around.
