Go to www.shopbot.com. (http://www.shopbottools.com.) They have already built one. You might get some ideas. Where do you live? Shopbot tools is located in North Carolina, I think.

Sam,
I just recently finished reading a book called CNC robotics by Geoff Williams $34.95 on the book but bought it on Amazon.com for way less.ISBN 0-07-141828-8

It is the author's step by step account of making a CNC router. It is a great reference, and fairly thorough, but if you aren't familiar with making your own electronics like PC boards you may want to enlist the help of an engineer or other electronics specialist. I have hopes of building a similar project with my students based on his design ideas. By the way the book describes everything from the structure, to electronics to programming. It's pretty thorough, and well worth the read even if you don't do the project.

Sam,
I forgot to say, the author uses a free download of Kcam for software. It has a trial period, then you pay a fairly mominal fee if you want to keep it. Do a search and you will find it on the net.
