1998, aluminum. Early prototype for Tappers made using a three axis CNC mill. I designed the part using Solid Works. I did not make the final Tappers in this style because of the long machining time required to cut the curved surfaces.

Adaptive Lock, 1997, plastic, foam, lock, and key. The black plastic parts were machined using a CNC mill. The blue part is structural foam, which I shaped using hand tools. The first two images show a rotatable lever assist which is trapped in the oval base. I turned the rotational interlocking parts on a lathe before cutting them on the mill.
