Rlrhett,
Hey man thanks for the interest in my project! Sorry for the big delays. I had a little run in between my mill and a piece of quilt maple. Kinda took the wind (and the budget) out of my sails. I have some new maple for the top, I just need to get goin and make some time. I just need to ask my wife and my kids and my boss "what's really more important here?"
Mattia,
My interest in CNC building comes primarily from my occupation. I program and run these machines all day long. It's a skill set I already have for the most part. Granted most of what I do for work is only 2D. I enjoy messin with this stuff. You are correct though that I have alot of time into the 3D design.
As far a using CNC for one off stuff, this is really common in the prototype industry, at least where I am from. I have a friend who CNCs one off prototypes for a living. He cuts everything from modeling foam and plastic to tool steel. Most of what he does are plastic appearance models for consumer electronics. Things like cell phones and MP3 players. Once you get proficient with 3D modeling software, its a short jump the CNC machine.
