If you dismantle the whole thing, you're already into a lot of work. Now, the beads will do a lovely job on all the metal, like the backcheck wires -- but if you have a Schwander action with tired little threads holding the hammer springs, the threads may give up the ghost. Ditto old flaky bridle tapes, of course. And the blasting will etch the wood. It'll be clean, but have little ridges, worse on softwood like keys, of course. As I've mentioned, compressed air will tear the damper felt, and of course, blasting with beads may not only tear it but fill it with beads as well. Tired old spring punchings or anything moth-eaten may just fall out or disappear. Of course, you'd want to replace these anyway, so that may be a benefit. Also, the filthier parts are, the more junk gets mixed in with the beads, which need more filtering and clog up the gun more. And one must figure the time involved. How much is pretty and clean worth? Not disabling problems, of course, and using a fairly low pressure helps. Susan Kline
