I did some practice pieces using some scrap steel parts.
I located the first hole as accurately as I could, then drilled the rest
using the steel part as a guide. I started each cut by hand just turning
the chuck until it was in a bit and then turned the power on. The
resulting hole was about as good as it gets with zero tearaway. The bolt
fit perfectly with the fit just enough friction to hold the bolt in by
itself.

It sounds like your workmanship illustrates the difference between
a builder and a craftsman.

Thanks, but I'm afraid my results aren't reflecting that!
I suppose my interest in making the airplane as straight and safe as
possible is more related to my uncertainty about what's safe to let slide
than any desire to make a Grand Champion. I simply don't know enough about
the things to say "yeah, that's good enough"
Having said that, I do enjoy the thrill of holding a nicely made piece in
my hands. Hopefully more of them will be like that than not when I'm done!
