I thought of that...right after I drilled & tapped the first two holes.
So, that would really work with any number of holes; once I have the
circle diameter known and marked, pick a point, determine the spacing,
and walk it around the circle. If I didn't screw something up, it'll
all line up to the original hole when I get all the way around - yes?

Wow, that metalwebnews.com site has some good info on it... time to
spend some quality reading time there.

Thanks,
