[pianotech] Broadwood bridge agraffes

[William Truitt]

Thanks for the pictures, David.  I would love to see some more pictures of
the layout of the top agraffes with the plate and pinblock area.

 

How clean is the sound?  Do you hear any buzzes, zings, or overtones coming
off those agraffes?

Subject: [pianotech] Broadwood bridge agraffes

 

I tuned the Broadwood upright (Number 129708) of a new client last Saturday.
I was intrigued to discover that both bridges have agraffes for all strings.
In addition there are agraffes with built-in V-bar at the top of the
strings.  The bass bridge has a height of 2 3/4".  The trichords are
individual strings.  The plate is of very solid design.

I didn't realise that Broadwood uprights ever had bridge agraffes, unless
it's been referred to on here previously and I missed it.  There is a patent
number stamped into each agraffe. The patent number for the top agraffes is
268062

Nice piano.

I have to go back to replace a missing key covering (the customer forgot to
tell me that one was mising and I didn't have any with me), so let me know
if there is anything else I should measure or photograph!

Best regards,

David Boyce.
