Okay; second question: I'm about to rebuild the pumping bellows from
a Baldwin Manualo. These have been rebuilt before, about 20 years
ago, but the hinges on the pumping bellows failed and the cloth tore.
I notice there are thick felt pads (2-1/4" x 1/2", 3/4" thick) glued
on the outside of the bellows cloth to keep them from closing fully.
I can't imagine these being original, especially since they are pieces
of felt glued together to get that thickness. Any suggestions?
Also, should these bellow have stiffening cardboard on them? I haven't
taken the cloth off yet, but it feels like there is some there. Any
suggestions? Especially I wonder if I should reinforce the pumping
bellows hinges, since that's where these failed. The rest of the piano
appears to have been well rebuilt.
P.S.: I've done many players, but this is my first Manualo.
(How did I manage that all these years?)
