[pianotech] Fixing stripped screws

I've used the toothpick repair many, many times.  I am intrigued with
the buckskin/titebond glue fix.  Can someone enlighten me on it?
Thickness of buckskin?  Is the buckskin inserted in the hole shaped like
a funnel?  I was unable to find Gault's article.

Joy!

The problem with toothpick and similar repairs is that it doesn't
distribute the material evenly around the stripped hole. I thought the
paper towel idea sounded promising and I too will try it. It would seem
that if you make a small tube of the paper and insert it into the hole
it will already have a "pilot" hole. 

I too have used leather successfully and it does make me feel like more
of a craftsman for some reason. Maybe its just because its a good "old
school" repair. I also tend to lean towards less toxic repairs. So I
prefer to use Ballistol or Alcohol/water over Protek (But I still find
myself still using it) for freeing up action centers, and aliphatic
resin glue over CA glue. 

I've often thought that there is a good analogy between drugs and
certain chemicals used by piano technicians. They are quick fixes and
are highly addictive, but may not have have long term benefit. We may
find that all the actions Proteked (a new verb!) in the 90's will start
seizing up in the next decade. We don't really know the long term affect
of these modern products.

Kerry,
I have no idea. A fellow listee made the suggestion a few days ago and
I'm willing to give it a try.
Best,

Reservations about the longevity of glue-soaked paper aside, if you
stuff the hole full and then harden it, wouldn't you then have to create
some kind of pilot hole? If you can just shove the screw in and start
it, what does that say about the firmness of the repair?

List,.

I'm on board with Jons suggestion.

Who hasn't removed a screw thats been repaired with toothpicks or
whatever and had a pile of splinters and saw dust come out. The late
Journal editor Don Galt suggested in the journal the leather-tightbond
method about 30 years ago and it has worked for me. I will try the paper
towel -CA suggestion at my next opportunity.
