I have a 1/5 HP 1725 rpm motor. Would that be a sufficient motor to tumble a 10#-15# barrel? I'm trying to figure out what configuration for my next tumbler if I want to tumble multiple small 5# barrels or just a single larger barrel. Thank you, suggestions are welcome.

Yes as far as big enough for a 15# capacity..possibly as much as 20-25# total weight.. it's a rolling torque needed and you will be reducing the rpm through pulleys but raising the torque at the drive "axle". Multiple barrels are more useful overall. Several stages at once is possible. Also several sizes are possible.. even to the point of using just one big one to do a rough tumble... Only problem is differing size diameters will make differing rpm's on the barrels unless you only use one pipe/barrel size and just make them longer/shorter to make differing weight sizes.

Barrel RPM should be different, the surface speed of the barrel diameter is what's important, so smaller drums will spin faster.

Should work fine. I'm roughing with a 12" barrel {6 gallon capacity} at 27 R.P.M. with a 1/6 hp motor and it is working well. Average total loaded barrel weight 107 lbs.

Good deal. I certainly wasnt expecting for it to tumble that big of loads, but now that ive read everyones input it makes me feel much better with heavier barrels. The barrels I'll be using are 4" dia. And 12"L PVC until I can get some 6-8" PVC. I'll do some experimenting with different size pulleys once I gather all the materials and put this thing together.

Should work just fine. Do your homework first. Make sure your motor is rated for continuous duty use. If it's not you run the risk of frying the motor.
