A little proof of concept today. The goal is to rapidly produce quality small turnings.
A 4" diameter piece of badly checked holly was the test piece.
First operation is to make a 1" holding tenon on one end. Blank was held upright in the vise on a milling machine. the spinning cutter moves in a circular path removing excess material to leave a 1" tenon.
The tenon-ed blank is next held in a rotating headstock's collet with the cutter following the contour path. The picture shows the finish pass after a roughing cut to remove the bulk of material.
Last picture shows the blank after the outside is finished and a tenon is left to hold for the inside turning. Maybe tomorrow for the inside cutting.
So far, about 2 minutes actual cutting time.
