When I last overhauled the player mechanism in my Welte Licensee grand
in 1973 as a teenager, I did a number of stupid things.  Yes, I used
some white glue, and now, doing it over again, I've paid for that
mistake plenty.

One of the other things I wish I hadn't done is to have replaced most
of the leather nuts in the drawer and on the lift wires between the
stack and the piano action.  I think they came from APSCO.  The leather
has corroded the steel threads pretty badly wherever the nuts were
replaced.  The few original nuts which remain have not damaged the
steel in this way.

A knowledgeable friend suggested that today's (or 1973's) tanning
methods resulted in corrosive materials being left behind in the
leather.  Since I learned my lesson with white glue,  and now that
I am older and supposed to be smarter, I don't want to do any harm.
But, the same friend gave me a big bag of nice soft nylon nuts to
replace the leather ones.  I'm sure someone out there in MMD land has
faced the same dilemma, and there is a clear theme from everyone's
postings, "use original materials whenever possible."  However, the
nylon would appear to be a better choice insofar as the corrosion
issue goes.

Is there a better idea?  If the nylon nuts are okay, then how do you
glue felt punchings to them?  In the grand stack, a felt button gets
glued to the nut where it's lifted by the pneumatic finger.  In my
trials, nothing seems to want to stick to nylon.  Help!

Many thanks, folks
