These Keys are not for locks.
For those of you who would like to know how it's done...
...here is the most recent "Key Top" repair I did.
PVC-E Glue is a special water soluble glue that dries hard and holds great.
The glue is applied to the wood side then the key top placed on top.
The brass "iron" is then clamped on top of the key top.
The clamped on iron is then heated to cure the glue.
It should not get hot enough to burn any of the wood or
discolor the key top - very high heat will yellow the
ivory...then you're really in a mess...
Here are multiple key top clamps at work. Each of the brass tops holds the heat
until the PVC cement is cured.
The clamped key tops are then left to harden. The glue never really hardens - it just
sort of dries- but hardens clear.
This is not for the amateur- careful top preparation is needed- and careful sanding
after word as well.
Here is my assistant showing all but six complete (He left the other six in the garage)
One of the issues I had to deal with is about 60 of these key tops came to
me in a 'baggie'...a real puzzle to figure out which key top went with which key.
My other helper (wife) sat and did a remarkable job in matching up the key
tops to their respective keys. It was with the subtle hints of all the years of
'finger dirt' which gave away the locations to which the key tops belong.
Since the 'key backs' were also loose, they were reglued
In all, it was 6-weeks of glue-intensive work. The actual labor involved was
pretty minimal but the time to set the glue and remove the glue that squeezes
out is the laborious part.
This was a perfect job- because when I looked at my OWN piano-
I thought, "Wow -I have to make mine look like this."
(I got a new micrometer out of the deal- to help measure the key-widths and
the key top variances.) I consider myself an expert now at installing key tops.
Anyone have any spare keys laying around?
