How about plugging the hole completely with lock N' Stitch screws?
Once the hole is filled it could be re-drilled and re-tapped as original.
If you are not familiar with Lock N' Stitch screws, they are special metal
fusing screws used for repairing cast iron and have recently become a popular
method of repairing cracked plates. I successfully repaired a broken
plate about a year ago with these. Anyway, this may work. The
link specific to this product, ("L" series pins), is here:

<p>Lock N' Stitch also makes inserts specifically for repairing cast iron
screw holes. The link to this product is here:

<font size=-1>Hi List!</font> <font size=-1>I
have spent the past couple of hours working on a Steinway L from 1927 with
a broken agraffe. It broke sometime while the family was on vacation.
I have replaced a few of these in the past without incident. The
problem:</font> <font size=-1>The remainder would not come out!
It seemed to be fused to the plate. I tried everything including
ez outs. I finally drilled it out using successively larger bits
until it was mostly gone. I left the hole small so the new agraffe
could "get a grip" as it turned. It turned in "very hard" seemingly
resulting in a very tight fit. I put the strings back on. Just
as it approached pitch the entire agraffe popped out of the hole.
Enough for today! The lady is a sweetheart who has lived long enough
to know that not everything goes as planned.</font> <font size=-1>The
Question:</font> <font size=-1>Is it possible to shim the agraffe
with the old metal pinblock shimming material to get a tighter fit.
Is there a larger size thread on some agraffes that would fit tighter?
Any suggestions from those who've been there, done that?</font> <font size=-1>Thanks!</font> <font size=-1>Ray
