Spraying aggraffes w/lacquer!

[jolly roger]

Hi John,
               Perhaps I should have made myself clear in my order of doing
things.

1. Clean the agraffes.
2. Spray them with a mist coat of lacquer.
3. Ream them.  ( best of both worlds,  protective coat and virgin brass in the
holes.)

I also carefully ream new agraffes, many of the new ones have little machine
burrs than can be noisy. I also spray them.   I have encountered no problems,
and they stay nice and bright for a long time.

A lot of agraffe noise and loss of power can be caused, if the strings have
not
been lifted.  On more than one occasion, I have had calls on noisy strings,
and
the problem has been solved just by lifting all the strings. 

Clean correct geometry on all bearing points is essential for clean tone and
quality voicing.  An extra few hours of work on the detailing in this area
yields big dividends for years to come.

Regards Roger
