In this job I removed the action to my shop. This time I = experimented with HOT MELT GLUE and it works the best of any of my remedies so = far.  The hot glue is thick enough to not get absorbed into the felt and sets up = faster than CA glue with no clamping.

(spreading hammers) List, I'm working on a late 1980's era <st1:place = w:st="on">Baldwin</st1:place> spinet.  It seems to have been subjected to some excessive humidity = at some point in its life, but is in pretty good shape.  Some of the = hammers in the bass section have butterflied (there are no staples in these hammers).  My question is, short of removing the action, is there = any efficient way to glue and clamp these back together?  (this piano = belongs to my sister in-law, and I have limited time to work on it).  = Preferred glues? Thanks for any help. -------------------------------------------------------------------------= ----------------------------------- -Court Stewart   I have applied thick CA, sprayed with kicker, and squish together with = fingers and hold for five or ten seconds - done. I must admit though, this has = always been on an older piano. On the ones I have done like this the resultant = tone seems quite consistent with the unaffected hammers.
