I found this posting on the American Science Surplus website
The Better Rotary Tool
For bigger, or longer, projects, and hands-free operation. This
1/4-hp flex-shaft grinder has a 43" long flexible shaft, a keyed
chuck that accepts bits up to 5/32", a variable-speed control
foot-pedal power switch, and a comfortable 1" dia hand grip. The
motor runs 500 to 22,000 rpm, operates on 120VAC, measures 3-1/4"
dia x 4" long, and has a sturdy hook to hang it from an
over-the-bench shelf. Comes in a blow-molded storage case and
includes approx (40) 1/8" shank tool bits (burrs, cutters, and
polishers). Includes replacement brushes. Intermittent duty.
I already blew about $200 on a Foredom for myself, but this seems
like an alternative for anyone else on the list who might not
currently have the wherewithal to do the same. For people who already
have flexshafts, the store also had a bunch of drill bits and
polishing thingies available. Do many people use the tools/materials
from this site? What are your experiences with them?
I have no connection or financial interest in this store (usual
disclaimer?) except that I got to visit the Geneva retail outlet the
other week, and it was AMAZING- stuffed to the gills with all sorts
