One more comment about repairing stripped wood threads and I'll move
on.  If you can find them, wooden "shoe pegs" make a more palatable
substitute for tooth picks.  Typically made of lemon wood, these
square, pointed pegs were once a staple of the hand-made shoe industry.
Dab a little Elmer's Glue on the tip and pound it into the stripped
hole, let it set, cut flush if necessary and use an awl to provide a
pilot hole to keep the screw centered.

One source for them is at http://www.panhandleleather.com/Nails_c15.htm 
Two sizes are available: 1/16" square x 13/16" long, or 3/32" square x
7/8" long.  Either size is $15 (plus presumably shipping) for a "quart
box" of unspecified quantity, but for me it would be a lifetime supply
were I to need any beyond my current supply of several hundred pieces.

You can also find them on Amazon or eBay for, curiously, the same $39
price, but again, no actual quantity is given.  I don't suppose I would
want to count them either, but you'd think at least an estimate beyond
"one pile" could be given.
