Working on a Kohler & Campbell grand model SKG-500S s/n IQGG0500 The action has a real noticeable noise on key return. I think I've isolated it to the hammer knuckle.... used a piece of action cloth between the knuckle/jack, the noise disappeared, remove it and it returns. Is there anything that can be done to lessen the noise, shy of replacing the knuckle? Les K LK Piano (734)657-7034 -------------- next part -------------- An HTML attachment was scrubbed...
