What is a CNC Machine?

A CNC (computer numerical control) router cuts plywood or other materials according to instructions from a computer, usually from a CAD drawing. All of the downloadable designs shown here are designed to be cut out on a CNC router. In an Absolut World, technology like this will be available as a neighborhood service like a Kinko's- you will download a design and send it to the machine, and then pick it up when your order is ready.
They are big machines, designed to handle full sheets of plywood, but in an Absolut world you may want to have one at home; right now you can buy little ones at Sears for under $ 2,000.
The actual machine they are selling is a Carvewright, a compact and powerful Woodcarving Machine which measures a mere 15x 18x 26" inches. It's rising-head and feed through configuration accepts work pieces 14.5 inches wide, 5 inches high, and with proper support nearly any desired length.
If you are really handy, you can build one yourself; Plans and specifications for the MechMate here.
