The short length of time a key rebush job lasts in a heavy use institutional environment is daunting. How often can we afford to rebush? Every five years or less? If you polish the key pins with FLITZ metal polish then lubricate with McLube clear or GlideAll and lubricate the bushings with the same you can make a set of bushings last ten to fifteen years before needing rebushing. Having worked in a university setting I have had piano performance coaching studios feel like rebushed yesterday after ten years of use using this procedure. I like the steam idea. I have also wanted to use warm water and Woolite for soaking bushings and then inserting cauls for sizing. Repolish pins, relube all and set out for a long term test. Newton nhunt@jagat.com
