Wow talk about team players....

As others have said things about copyrights and patents, I do agree with being original. No problem on that part.

I wished I could somehow help but I know nothing about cnc, I cant use a cad program, but I did use to play around with mechanical drawing.
It is odd I took mechanical drawing in my senior year in high school as an easy way out... I was so mad at myself for not taking it my junior year and then taking advanced in my senior year.
My senior year we had to draw the blue prints to our dream house. Mine was a round house, 3 story with a drive in basement. swimming pool that covered 1/4 of the house and was curved to go along with the house. I also had a glass elevator in the center of the house. Back in TN at that time it was estimated at 1.5million dollars to build that house, that was in 1981.
