I love the idea of using my own hands to be the CNC machiine, not sure how it would work for panels the size of sidewalls or hatch spars, but the potential of the idea is cool.
For those of you who play with CNC machines, I was wondering about the cost of this machine VS. a regular rig capable of 4x8' plywood.
