A 12 volt 3 = amp transformer will do it in about 5 seconds. But try it slowly. It = might need to smoke to do the job. Carl Meyer Assoc.

After finding that a bit of center pin lube = was not going to do it, I treated them with Baldwin's bushing shrinking = formula of methenol, water and dissolved Ivory soap chips. I dried them = with the heat gun and it seemed to work fine. Now seven years later she = wants to sell the piano and the wippen centers are sluggish again. Part = of the problem is that the console action and keys are so light, that = any friction anywhere is going to keep the action from returning. I could repin them, but she doesn't want to spend that much since = frankly, the piano is not worth that much. Does anyone have a sure fire = bushing treatment that will loosen the most stubborn centers? Dave Bunch ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
