Ed,
Interesting that you eliminated the false beats by pressing against the =
HITCH PIN.
If you ment bridge pin, I regularly use CA glue on old uprights to calm =
them down.=20

After tuning the piano to pitch,the piano is placed on my tilter at a =
45% ( the wheels the tilter has are just right to hold the piano there ) =
 and CA is dropped as close to the top of the base of the bridge pin as =
possible.
Top pin only, as the CA usually runs down the string to the bottom pin =
and onto the under side of the bridge. If you are not careful you could =
make a mess, but unlikely.
It usually gets two passes with the CA from top treble to the high =
tenor.
Everything that is reachable without taking the bass strings off or =
moving them.
Use the thin CA.

  Subject: hitch pins


  I have a Hoffman piano (my book lists several Hoffman types, but not =
this one, so I don't know the year, probably 1910-1920), previously a =
player, with badly ringing strings starting about C6.  I isolated =
several strings and determined that pressing against the hitch pins =
eliminated the problem.  In the past I have made improvement by gently =
tapping hitch pins in and/or using epoxy on them. =20
    My question is, what kind of danger do I run by tapping in these =
pins.  Am I likely to split the bridge? =20
  Other considerations??
