[CAUT] Mason & Hamlin agraffes

[Mark Cramer]

Actually no Don, I don't recommend the drill press. The bit can grab and
make a mess (take my word, or do I need to send photo? ;>)

 

The bit will self-center in the hole, and I will suggest once more that the
variable speed drill with slip clutch is the ticket. You want to hold the
drill with a loose grip and light pressure, so that if the bit should catch,
the impact is wasted, rather than transferred to the agraffe. 

 

i.e.: the bit needs to be able to "chatter" if necessary, to prevent a
sudden calamity.

 

So yes, you do need to remove the agraffe and be able to hold it flat to
your work-surface. (my simple holding fixture works great, sorry the
description may be a bit vague)

 

In any case, I agree this is not a comfortable repair to do on-site.

 

Good luck!

Mark, David, Ron & Ric,

 

Thanks for your replies to my questions. I just spoke to my customer and she
has agreed to try replacing the strings on the note. If I can get the
agraffe out without any fuss I will try polishing the holes as shown by Paul
in the March 05 Journal. Trying to use the reamer during in home service
could get a bit dicey. It needs to be perfectly still, preferably at a drill
press to ream correctly. Paul's point about the reamers leaving striations
is a good one. The buffing method is more work but perhaps better for in
home service. We'll give it a try and hopefully this will work for now. She
has not complained of other notes having this buzz but I would bet that will
come up at another time.

 

Thanks again,

Don
