[pianotech] Plastic Damper flanges

[David Weiss]

Hi Rob,

 

I just finished a similar job on a Mason Hamlin console.  Beautiful piano on
the outside, but it had plastic backchecks, jack flanges, and damper
flanges.  I was lucky though, about 20 damper levers were intact and I used
those as guides.    The new damper levers  I got from Schaff, and they were
an exact match to the originals.  The part number is 3786J.  

 

The advice you has received so far has been great.  Just to echo what others
have said I strongly recommend doing this job in your shop, and be sure to
charge enough, it takes a chunk of time.

 

Good luck.

Greetings and happy new year!

 

This is from a 1955 Story & Clark console.  Damper flanges are made of
extremely brittle plastic. The lightest of touch and they disintegrate in
your hands. When I opened the lid on the piano, all the dampers were piled
up on top of each other at the bass end. I guess they tilted it when they
moved it and the damper flanges self-destructed. 

 

Fortunately, all the other flanges on the piano are made of wood.

 

I'm unable to get any specs on the flanges due to the fact that not a single
one of them is whole. Best I can estimate, from the best one I could find is
that the distance from the center pin to the center of the screw hole is
around 15mm, and the spring appears to be about 1" long from it's attachment
to the apex of the bend in the spring.

 

Does anyone have any specs for this?  Or does it look like the standard
spinet flange from Schaff, etc. would work?

 

Also, if anyone has any hints or tips as to how best to sort the pile of
damper levers from the mayhem it's in, into the correct order it needs to be
in, I'd appreciate it...  and no, they aren't numbered...  :-/

Regards,
