Some questions about this contraption -

Do you need the output speeds to be infinitely variable between your selected high and low, or incrementally? The design will be different depending on that.

Fella's - and Ladies .... I need a little help.

I need to build a machine that uses a 1 HP Capacitor start 120v
electric motor that turns at 3350 rpm. The motor - by way of pulleys -
will drive a shaft whose rotational speed should have a controllable
range from 0 to 200 RPM.

I'm hoping that some of you folk out there know about such stuff and can
help me with suggestions on how to get it done. - speed controllers,
variable diameter pulleys, or what ever. I am open to suggestions.
Specifics and specifications would be of a big help.

I would appreciate any input.

Thanks.
