[pianotech] hammer heads unglued

[Tony Caught]

Hi Les

 

Below is the catalogue page  for hammer rivets.

 

I have used these quite successfully in Darwin Australia where the humidity
can be very high (80 to90% RH in the wet is normal). 

Drill a hole through the hammer head in the same position as you see most
hammers stapled. Insert rivet, pull through tight then bend the two prongs
to either side and cut off.  Many of the Yamahas made in Taiwan had hammers
without staples and the felt lifted of those hammers too.

I have a church client with a bunch of Baldwin Hamiltons.  I'm replacing
hammers on at least one with virtually all hammer felts ungled from the
moldings.    If the heads have not actually come loose (as on another piano)
can I some how prevent the hammers from separating?    (The church has
significant humidity problems, and I'm putting damppchasers in all their
uprights which are in areas where humidity is a real problem.)

 

Thanks
