[AMRadio] Motorized Variables

Thanks a million, you definitely helped.  I have two 4 RPM 115 vac gear 
motors I want to use and with your advice it appears I can.  If the 4 
RPM is too slow I can always gear it up a little faster.  They are 
capacitor start and bi directional, so that should work well.  I want to 
use mechanical limit switches, but with the number of turns it takes to 
run the full range of a vacuum variable I don't exactly know how I'll go 
about it.  If it doesn't work out to be too large I may put a gear with 
a peg in it that would turn only one revolution from start to finish and 
activate the limit switch at each end.  Any ideas? 

Guru or not, if anyone has an idea or suggestion, please, let me know.
