Glue Joints

[Bob Anderson]

In the long discussion of hide glue vs aliphatic resins, creep, etc. I
haven't seen any discussion of one glue joint that has been a problem
for me in old pianos - the joint between the upt. jack flange and
wippen. This joint is often broken in old pianos and nearly only in old
pianos. The glue is invariably hide glue. If hide glue is as good as
advertised, why is this joint such a problem. Am I the only one with the
problem, or are there others out there?
