My piano's dampers (it's a Yamaha p2) are glued onto a kind of capstan (a dowel with a hole in it that sits vertically on the damper wire), AT AN ANGLE.
Most dampers on uprights are aligned with the string they are damping by BENDING the damper wire. This is fairly easy to do.
On this piano, the damper wires are all totally vertical. For strings that run at an angle, the bass and most of the treble, the damper block is glued on at the angle of the string.
It's a great idea but to put new dampers in you have to know the exact angle for each string in order to position the damper block on the capstan when you glue them together.
Replacing just one damper is do-able inside the piano, by placing the damper block, with freshly applied glue on its back, against the string(s), then pressing the capstan against the block and holding it in place until the glue starts to dry.
But that just does not work for a series of dampers.
I need to put in six new damper blocks in a section of the piano where each set of strings is at a slightly different angle. Doing this using wet glue just does not work.
There has to be some technician out there who works on pianos like this and there must be some easy (or easier) way to angle each damper block at the correct angle OUTside the piano. The capstans could then be placed straight up and down on the already angled damper blocks, and when the glue dries each damper would be angled exactly correctly.
Is there an expert on this particular kind of damper system out there? Does anyone know if all Yamaha uprights are set up like this?
If so, what is the secret to replacing more than one damper?
