I have a 2" chop saw that works great on metal and wood but it runs a
little too fast for plastic. I would like to "dial it down". I think
at lower speed it would work great on plastic as well. I have seen
the foot pedal type rheostats but I was wondering if anyone sells one
with a knob / dial that I can plug it into and set it at a low speed.

I obviously don't know where you are in the world but these things....

...are readily available for woodworking routers and other power tools. I have a
similar one to control the cutter speed on a CNC router/engraver I built and it
works very well.

Thanks Larry,

That's exactly what I am looking for. We have a Harbor Freight here
locally.

Taking this thread a bit off-topic, Model Expo is now selling a
modeler's drill press for seventy bucks. I have been looking for a
little drill press for my modeling bench for some time, and recently
took a flyer and ordered it without seeing any reviews.

It is okay. Base casting is a little rough, but that does not affect
the operation. The drill has a "speed control", but it is the poorest
part of the system. HOWEVER, drilling does not require super-good
speed control, and it is adequate, though just, for drilling plastic,
wood, and brass. I have no idea what technology (resistive or solid
state chopping) the speed control uses.

Be careful, the motor on the saw must be a brush type motor for any of the
speed controls you are looking at to work. If it is a brush motorm, the
Harbor Freight router speed control, or a fceiling fan motor speed
controller will work.

OTOH if the motor is induction, split phase, capacitor run etc these
devgices will not work and may harm the motor.
