Broken Keys

[David's Email]

I'm sure you've gone through the archives, right?   They will be repairable.  I use titebond.   Most likely broken at the balance rail pin.  Remove key, flex it a bit and see it is just partially broken.  Often a single edge razor blade can be used to get glue in the cracks, then more flexing to get the glue to move around in the joint.   Set down on a flat surface and use it neighbor for clamping.   Maybe a little wax paper between.  The two keys should look exactly the same on the flat surface.   All parts the same height, then you know you gluing the key correctly.  You can use both neighbors if you like or just some pieces of wood and clamp with a clamp of your choice.  Usually the key just closes together.   If completely broken, you may hve better luck finishing the break, then carefully dry-fitting the key to make sure it slides together perfectly.  Careful with the splintery ends.  Put glue on all the surfaces.   Then carefully slide together and clamp.

        I will be facing my first broken keys situation this coming week.

        I have a client who has two broken keys needing repaired.  What is the appropriate process to assess this situation (i.e., can it be done in the home at the appointment, what do I need to bring in my repair kit)?  And, if the keys are irrepairable, what is the proper way to address that situation.

        Thank you!
        Matthew
