Agraffe reaming

I did not noticed you where reaming without unscrewing the agrafes. Is it
convenient ? I prefer to have a close look inside the hole with a magnifier,
but indeed placement problems arise when unscrewed.

The rod is bronze beryllium I was said, but the references I see are about
copper beryllium on the different web sites I find..

Is bronze easy to weld on iron ?

  Normally, I would simply replace the agraffes.  In this case, they are an
odd size that are not currently being manufactured.  My options are to try
and salvage the old agraffes, or drill out the plate and retap to 1/4".
The piano is a 5'2" Knabe that I would prefer to keep costs down on--at the
request of the customer.

    Hello David,

    I'd say that we possibly have to put some agrafe back in reverse
position, so it is better to ream the 2 sides to begin with.

    I noticed too that it may be advisable to have some good tool to ream
the seat of the agrafes, as even when reinserting in the original place, we
may uses some washers to have it straight, and then the string's height is
compromised more than wanted.

    Nowadays, if the piano is worth it, a new set of agrafes not too
expensive.
    And new berilium (?) bronze rods in the reinforced agrafes as seen in
some Bosendorfers or German pianos ( I writed about using Iridium, it was a
mistake).

    The same rods can be used to replace a worn capo.

    Best to all.

      When reaming old agraffes to clean up the--what is that hole in the
agraffe called, is it the "torus", it appears to be a toroidal
shape?--anyway, is it just as important to ream the non-speaking side as it
is the speaking side?  Not that it's a big deal to turn them around with an
agraffe wrench and then turn them back, but if it doesn't really matter...
