[pianotech] Bridge agraffes FYI

[Ron Nossaman]

I don't know what the old existing bridge agraffes weigh, but a modern 
small shank trichord is a bit over 8 grams. Sixty of them on a long 
bridge would be 480 grams (16.9 oz), which would tend to make for a 
clear though not very loud and lively tone.
