[TheForge] Buffalo forge blower/ Magic of motors

[Bruce Freeman]

I'm no expert, but if it says to use a rheostat, DON'T
use a gate.  Use a diverter instead - an air leak of
some sort.  That way you won't be lugging the motor,
just wasting some of its output.

It shouldn't be too hard to come up with a rheostat. 
I'm not sure, but one of those foot pedals from an old
sewing machine might do the trick.
