<font face="Courier New, Courier, monospace">I have used hammer shanks
for oversized holes for the kind of knobs which have screws, <br>
put the screws into end grain, come back two years later, and found
neat 7/32" holes <br>
instead of the knobs I had left there. <br>
<br>
Leather, use leather and white glue. If the holes are egged out, you
can even fold <br>
the leather over, or use layers of it. It works. <br>
<br>
None of the wood options (shoe pegs, toothpicks, dowels, etc.) work as
well <br>
(except plugs made by a plug cutter), because the screw threads eat
into the grain. <br>
<br>
Leather leather leather and Elmer's (repeat ad infinitum till you try
it and see <br>
how well it works.) <br>

On the finished repair pic, I know they didn't match. Those were the
screws that were with it....maybe from a previous repair attempt. I
didn't have matching screws the correct size on hand. I always try to
use the existing screws when possible. This was at a school where the
piano got hard use and this was not the only mismatched hardware on the
piano.
<br>
<br>
I did use a zinc screw in the plain wood picture, but that was the
first screw I found laying around.
<br>
<br>
As far as the end grain, yes, you are right. Short of cutting plugs
with a plug making tool (which I don't have, but ought to get), this
was far better, in my opinion and experience for most applications than
filling the messed up, "v"ed hole with toothpicks and/or shoepeg
dowels. I've seen dowel used hundreds of times in different places to
repair screw holes, and I personally have not had issues with
it.....yet. HOWEVER, you are absolutely correct, and they could
eventually strip out in time if under quite a bit of stress. I will
look into finding a plug cutter at a good price, cut a bunch and keep
them handy.
<br>
<br>
Suggestions on what type wood best for wood plugs?
<br>
<br>
Thanks!

Hmmm? Zinc Plated Phillips Screws?!!!! Please? Noooo! Then, we have
<br>
Hammershanks to fill with? Oh, goody, right into end grain. Lovely.
<br>
Sigh.
