I'm not really comfortable with building one. Tools kind of scare me. Computers don't. This is why I am so interested in CNC.
If your comfortable with building this device and feel you can build one well enough to build guitars why don't you see if you can build one for me? I'll pay you of course. It must be well built though, since I am sure you can not offer a warranty.
I'm sure that the plans forbid you from selling this product, so I will buy the plans from them and commission you to do the work.
Interested?
