Congrats! Sounds like it went pretty well, if you did it over a weekend!

Glad you like it. I have probably used makebore more than any other
of my 'cam' programs. I've still got a couple more to convert to the
portable format. I hadn't done a whole lot of testing under Linux after
making the conversions, but I was pretty sure it woold work fine there.

Ahh, one of my other programs - a peck drilling program, and a program to
do peck drilling on a circular pattern of holes. It doesn't use canned cycles,
so you have more freedom to do odd things with it, especially if you are
willing to modify the code a bit. I'll convert that one and put it on the web
page with the others.
