>>First, Kent said that doing key bushings and BR holes as one job seemseconomical, with which I wouldn't disagree, in principal, except, whatif, when doing the Balance bushings, all, or most of the holes are justfine. It would then be most economical if you are able to isolatethe affects of the bushing removal process. Steaming, as Barbaradoes, would seem to make additional work. Greetings, I use steam to remove the bushings, and the hole is automatically steamed, too. It is fast and doesn't stain the wood. I have an old fire extinguisher body, with a big bolt closing the hole where the gauge used to be. Brazed into a 2" hole in the bottom is the flange for a hot water heater element. Along the top is a row of drilled out zerk fittings, which act as nozzles. It all sits in a plywood cradle that the keys can be balanced over the holes. I can steam from one to four keys at once, and after getting the pattern going, I am removing bushings as fast as I can pick up a key and put it down. Even the white plastic glue is no problem with the heat applied by steam. I havent' noticed the balance holes needing any more than being opened back up to function tightly after the treatment. regards, Ed Foote RPT -------------- next part -------------- An HTML attachment was scrubbed...
