Broken Agraffe

[Marcel Carey]

Once in 29 years did I see an agraffe that broke with the strings still
in place. This was an old S&S M. The customer on the phone was telling
me that an agraffe had broken and I just wouldn't believe her. But she
was right. So I had to replace 2 strings in the tenor and the broken
thing. I had no problem removing it though. 
 
Now, I broke some either while trying to remove or put them back in. In
this case they were a little more trouble.

Avery-
 
I'm beginning to think this could be wierd. How could it break down in
the plate, within the length of the tapped, threaded hole?  How did the
top part come out?  Did it rip out part of the threads?
 
I replaced the agraffes on a 1970's D where holes had not been tapped
deep enough to take the agraffe shank. They had been forced in, smashing
the threads to fit.  And this required tapping the holes to proper depth
before putting in new agraffes.
 
If you don't have taps for agraffe holes, maybe you could borrow some
and bring them along.
