[CAUT] When to Restring

[Paul T Williams]

Who all makes agraffes? How many manufacturers and who uses/sells which?

I've had a couple of noisy agraffes too through the years.

I'm at least somewhat aware of the difference between duplexed 
capo sections of the scale and agraffed sections. I don't have 
the two confused. Whatever you believe you read, I most 
definitely didn't, and won't, blame agraffe noises on tuned 
duplexes, nor capo section noises on agraffes. I do know the 
difference, thanks.

Perhaps it's a matter of who makes the agraffe? I've had good 
results with Pianotek's agraffes with no prep whatsoever. My 
rebuilds that have remained local haven't been a problem. With 
the belly work and rebuilds that go elsewhere, I rely on the 
local tech to inform me of anything they don't like, that I 
ought to be working on improving. If any of them have 
experienced noisy agraffes as a result of them not having been 
polished before installation, none of them have mentioned it 
yet. When it proves to be problem enough to spend the time, 
I'll add the appropriate cost to the agraffe job and do it. I 
have no problem with the concept I just don't realistically 
see the need unless the agraffes are lousy.

Thanks Tim, I appreciate that. But again, I know the 
difference between agraffes and duplexes as well.
