key doublets

[Newton Hunt]

There is an easy solution.  CA.  But God help the poor schnook who has
to change the wires 18 years from now.

I have found the same problem on some older pianos.  The wire may well
go into the soft wood of the key and bending the wire makes it waggle
around at the bottom of the hole.

What is needed is wood or larger wires.

The wood is easier, long term.

I would make a jig to hold the key at the right angle and use a
Forestner bit to drill almost all the way through the key, cut hard wood
plugs, orient the grain cross wise.  Drill the new holes before trimming
off the plug ends so you will be drilling perpendicular to the plug. 
Push in new Backchecks.

Before starting check the geometry, wire lengths, etc.

Or you could ship them out to someone else who can do the work.

Just don't glue them suckers in, quite yet.
