>>What is a target rpm of a tumbler barrel? (say a 55 gal. barrel) And can I
>>run it on solar power??

i weas told 24 r.p.m._______ mine came out to be 29 r.p.m. and seems to
work just fine.
as to solar power i don't know________ mine runs off a 1/2 half h.p. 1725
motor with gear reduction box.  it is built out of 18" diameter 5/16" thick
iron pipe 5' long, mounted on pillow blocks, with a large shop vac hooked
on one end to suck dust, my tumbling medium is a couple of 5 gallon buckets
of "slugs" (punchings, donut holes) from "ironworkers",(the name for a type
of machine} that i cvould scavange from machine shops around the county. it
takes about 20 minutes for a wonderful finish, i love it, {and oh how i
hate using the makita with a wire cup} and consider it one of my most
important tools, yes it is noisy but i have it contained in it's own space
and well sound proofed.

hope this helps
