It had changed climates and the action centers were sluggish. I've encountered this many times before. But what I don't get is: why is it almost always remedied by shrinking only the hammer-butt center-pin bushings? Don't all the other center pin bushings swell as well (or flanges shrink, whatever the case may be)? I applied about 1:4 alcohol to water to all the hammer flange bushings, let it dry, and that freed them up pretty well, as it usually does. Still had to re-pin a few. But why aren't all the jacks, wippens, and dampers sluggish also? --David Nereson, RPT _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives __________________________________________________ Do You Yahoo!?
