How can i reduce the rpms of an electric motor for a tumbler? I think it's a larger sproket on the side opposite the motor will do it, but not completly sure.
Is there any calculation that will get me in the right ballpark? I would just go by trial and error but I don't have the motor in my posession yet. Thanks everyone

You may need to run a idler arbor, small gear on the motor to larger gear on the arbor idler, then small gear on the opposite end of the idler to larger gear on the tumbler axle. I think you divied the motor rpm by 3.14, then then time the rpm you are trying to achieve. Should give you the final drive ratio.
I have a 3000 rpm motor that has a 1" pulley. it goes to a 12" pulley on another shaft. Mouted right next to the 12" pulley is another 1" pulley that has a long belt that goes around my 55 gallon tumbler barrel. This has my tumbler going around 33 rpms. I have not timed it, but it seems to go very good. Also, it is geared down also, so big hides I want to dry will not lug it down either. The motor is a half horse.
I have the motor now, it's a 1/3hp @ 1725rpms. I would imangine that if I use the same set up Steve has I could probally get it down to 22rpm or somewhere around there.
In Van Dykes thier tumblers have an rpm of 6. Should I shoot for this slow of an rpm or will a faster rpm dry the cape faster with out damaging it. I will just be doing WT capes for now. Thanks for the info John and Steve!
