As I read through the thread I was getting increasingly disappointed as I am
not fond of using CA for virtually every application.
I then read Isaac's post and realized there may be others out there like me.
I purchased a pound of shoe pegs from a shoe repair shop about 30 years ago
and still have most of them they can be cut to size, both lengthwise and
crossways. They are made of maple so they are much more durable than
toothpicks.
As Isaac also pointed out for those larger holes, I save broken hammer
shanks and use them, again splitting them and cutting them to size as
needed.
I see no difference in time taken to perform the task, I always have
Titebond and shoepegs/broken shanks with me.

In both cases good old Titebond works quite well. It's also cheaper than CA
and I never have to worry about gluing the screw in and being unable to
remove it.

For those interested in obtaining a larger supply of shoepegs than Schaff
sells, perhaps a chapter, google shoe repair suppliers and check their sales
lists for shoepegs, their are a few that still supply them.
