I'm building a tumbler and am now trying to find a motor. Does anyone know of a motor that turns around 15 RPM that would be suitable (I would rather not use pulleys). I have looked in Grainger catalog but I'm not sure which motor to get? Thanks

It's the reduction gear. Electric motors are notoriously weak as they operate on magnetic fields and require very heavy armatures and coils to be considered powerful. Even a small motor can work a tumbler with the proper reduction gear assembly. A grill rotisserie can work on a small scale, but believe me, it WON'T turn a 30 gallon drum or larger. Somethings are just better (and cheaper) when bought already constructed and assembled.
Go back to your Grainger catalog and look under the gear reduction motor heading. They are in there, all set up and ready to go for about $250.00.
Good luck
and you'll make up the other half in frustration.....or like george said ....just buy a tumbler.....in the long run you'll be happier........good luck....god bless us every one

Gerry, I made my own tumbler for about $150.00. It is exactly like the store bought tumblers that 2 of my friends have and they paid about $600.00 or so for theirs. Of course I have my own welding machine so making the steel frame was easy for me. It uses the same belt and pulley system which must be pretty good or the store bought tumblers would use something else. Unless they are building a inferior product, which I don't think they are. These factury made tumblers are way overpriced IMO. But when there is little competition in the marked they can charge these kinds of prices for their products. Build it yourself and be proud of it every time you use it.
My friend and I built a nice tumbler and used a transmision from a riding lawn mower. Got it from a mower repair guy for FIVE BUCKS! Works great. But you will probably have to use a pulley or chain.
