Original question John Ross, I do like the idea of using the sand blaster with glass beads. I've been thinking for a while about a compressor. What else do you use the setup for, in addition to cleaning actions David Boyce Hi David, In the archives, you will find that some people use a specially made box, that collects the beads in the bottom, for reuse. I never got around to making one. The amount of beads I use, is not that great, so any saving I would make by reusing them is negligible, for me anyway. For major usage, a cabinet would be advisable. I use a handheld sandblaster that also is the reservoir for the beads. By trial and error I determine the pressure to use. Be sure to protect your face. To contain how far they spray, I just have a temporary frame, with heavy duty plastic. Initially I used sand at a low pressure, but it roughened the wood, so only used it once on the wood parts. Used it to clean the hammers for a while longer. Now I solely, use the beads. Probably only $2-$3 each use, not going to break the bank. Finish off, by more pressure, and just air. Could be done outside in the Summer, then a protection booth wouldn't be needed. i also use it to clean the wooden parts of keys.
