<DIV><BR></DIV>I wouldn't advocate using pins more than 1/2 size over what was
there originally. On an older piano like this, increasing more than .001" at
once runs the risk of cracking the birdseye. If a larger jump than this is
necessary may want to do some very careful wood reaming first, with a
roughened undersize pin.<BR><BR>- Mark Dierauf<BR><BR><A

do is to determine the size of pin that will be slightly larger than any of
the pins in the row of flanges, determine the proper straight sided reamer
for that pin size, and then go through the row, reaming the bushings for the
oversize pin. Don't spend time custom fitting various pin sizes to
each bushing, ie, if you have 19, 191/2, 20 sized pins in your hammer
flanges, find what reaming is needed to fit a size 21 1/2 pin in there and
then do all of them to that size. Odds are that the action will never
be pinned again, and if it does, there are still several sizes yet to go, if
needed. <BR>this procedure is not only as consistant as can be hoped
for, it is economically feasible. <BR>Regards, <BR></FONT><FONT face=Geneva
