World's Cheapest CNC machine @ $100??

[SuperCharg]

I do not have an engineering/electrical background but have CS degree and worked for a year doing blueprinting trying to help a company breakoff into a manuf. division during college. I am very interested in CNC - I would ultimately like to create a machine with an envelope of roughly 7' x 3' x 3'.

Keeping this in mind, I found this web site:
http://www.crankorgan.com/morph.htm
"Morph will cut a 12" X 12" by 1-1/4" part. The machine can be built for under $100"

Another CNC machine on the site @ $200 w/ envelope of over 9" x 14" x 3":
http://www.crankorgan.com/7thsojourn.htm

Since I have no knowledge of CNC (and not a whole lot of $$) do you guys think these kits would be a good place to start in reaching my goal of creating a large machine? Are there better plans I should look into, inorder to eventually reach my goal? What would be the difficulties in going from building a machine like the 7th Sojourn, listed above, to increasing the envelope to the size I need?

Any help appreciated, as I don't know what I'm doing!!

Have a look at this thread:http://www.rcgroups.com/forums/showt...threadid=62920

It is about a guy who built a 7th sojourn. (a few other machines thrown in there too)

Chris:
I bought the Brute plans. They're adequate, given the $30 price tag.
You may have to get creative finding (substituting?) some of the specified parts. Not all the items called for are as common as crankorgan seems to think.
