I hadn't thought of that idea either - thanks. Problem I see with that is
the shafts, AFAIR, are larger than the ball so wouldn't drill very deep.
I need to go through about an inch or more of wood.

After you got in a quarter inch or so you could switch to a straight bit.
Wandering won't be an issue at that point...


Or use a wire like they use for a root canal ....
