To answer your questions about tank tumblers, the best way to go is to buy the completed thing from Global Manufacturing. They used to sell it with or without the gear motor. You can get surplus gearmotors at a good price from: C&H Sales 2176 Colorado Blvd Pasedena CA 91117-9988 (800) 325-9465 Their free catalog has lots of other interesting things in it too, from electronic parts, to military optics, lab equipment etc. If you want to make one from scratch, I can tell you about one I used in my business for some time. It was made of 2x8 lumber, a couple of long pieces formed a 16" x 32" base; two end pieces held the bearings for the rollers. The rollers where approx 1/2" dia steel rod, covered with garden hose. The gear motor drives one of the rollers, the adjacent one (or two, for a two position tumbler), turn freely. It worked great, but was not really rugged enough for commercial use (fine for doing a dozen or so tanks a year, though). C&H has a selection of bearings, too, but you could probably just run the rollers through holes in the wood (no bearings) and replace the wood end pieces when the holes get worn (this should be ok as long as the roller speed is slow. Check for heat buildup/fire hazard on the first run and get some bearings if it looks like a problem). Buy the tumbling media locally so you don't get killed on shipping. Look under "abrasives" in the yellow pages. Tell them the application and they can recommend the size/grit and abrasive material. Don't use aluminum oxide in aluminum tanks. Some people use small steel screws as tumbling media too. Cadillac way to go is to buy ceramic cylinders or spheres from Global Manufacturing. I hope this helps! Sincerely, C.

I have looked at some motors and they all seem quite expensive. Also the type of glass beads which should be used and sources for the above. Thanks in advance.
