I have recently heard from a piano tech. who has been asked to take
over the maintenance of a harpsichord I made for a college some 20
years ago. After a faculty departure it wasn't used for quite a
while, but now they want it working again.
What is the best available published work on maintenance? For the
past many years I have been telling myself to write such an article,
but of course procrastination won the day as usual, and I never got
past a few illustrations which in any case I put somewhere safe(!)
and can't find at the moment . . .
