<html> Hi Alan,               Schaff used to sell partial sets of treble hammers, maybe they still do?  If so, that may be the best way to go. You can juice them up to match the old ones.

Customer (nursing home) won't pop for a complete rebuild but am replacing damper felt and blocks, hammer rest felt, etc., and otherwise getting it playable. Question One: Several of the very top treble hammers have wood peeking through deep grooves. Searched the PTG archives, Reblitz, Potter Course ... can't find any info on "buckskinning" hammers. Would appreciate a quick course and/or tips from the voices of "been-there." Question Two: Good old, innovative Chickering has those adjustable setouts at the action bolts--I'm not sure how to adjust these. They would effect blow distance and, to some extent, the strike line, I guess? Any hints? One last thing, a mystery: The back of the whole treble section has been worn down along the sticker rail. The flange screw heads are worn flat and the birdseye ends of the sticker tongues are worn flat, too. It may be obvious when I get back to the piano (an hour away) but I can't even IMAGINE what has been rubbing on this area with such force. Thanks, Alan R. Barnard</blockquote> </html>
