That's the simplest solution of all.

But not the most elegant! I've done just a bit of googling and haven't
found what I'm (you're) looking for. They make small tapered bits for
pilot holes, and I've found some larger ones made for metal, but no
dedicated ww'ing bits. I've got to figure that somebody makes them.
Don't chair makers need bits like these?

Also, if I do want to get ambitious, modifying a spade bit is also a good
suggestion.

Probably the least expensive as well. Now I want to find the real
McCoy.
