The first step is to draw up a set of plans . The frame plan shows the shape and spacing of every structural member . I do all of my drawings using CAD ( computer aided design ) which allows the component parts to be output to a CAM ( computer aided manufacturing ) program .
The frames will be milled from mahogany . The wood is roughed out about an inch oversize before being placed on the shopbot CNC router .
I cut a shallow groove into the MDF spoil board that shows where the outline of the frames will be cut before fastening the roughed out mahogany frame stock to the spoil board for cutting .
