[pianotech] tuning pin sizes: Boston & Essex?

[David M. Porritt]

Patrick:

 

I just looked and didn't find anything on the web site but I had thought
that Boston had a 12 year warranty and Essex something greater than 5.  My
memory isn't what it used to be but I'd check before doing anything serious.

Hi, I have a couple clients with recent (past the 5 year warranty, less than
10 years old) Boston and Essex grands. A few tuning pins have
less-than-borderline torque, particularly in this cold-dry New England
winter. I have a call back on the Essex ("This one note sounds horrible!!")
which I tuned back in November.

My options are drive pins (I'm visioning coils smashed to the plate, not a
good choice), use CA (my usual choice when dealing with decades old pianos),
or install a few oversize pins. Anyone know what length and diameter is the
standard on these models (Boston GP-163 II and Essex EGP161)? I recall
reading that Kawai and maybe Yamaha sometimes use a pin larger than 1/0 but
less than 2/0.

Thanks,

Patrick
