THE “SCULPTURE” ROCK LATHE

(A) “X” Assembly with motor and blade

The “Sculpture” is based on the simple XY linear movement principle. The X axis moves across the face of the work piece (from left to right) and is driven by a power feed screw. The Y axis is then left free to move up and down, guided by the template tracer arm follow- ing the shape of the template.

(B) “Y” Carriage

X AXIS

Y AXIS

A . The X assembly platform is powered by a gear motor driving a screw feed that moves the platform from left to right, keeping the cutting edge of the blade moving across the length of the work piece. B . The Y carriage assembly carries the X platform and moves it up and down, and is guided in its move- ment by the template tracer arm following the shape of the template. C . Work piece is held in place by the tightening rod. The work piece is rotated in place by a gearhead motor as the blade moves across the work piece, fol- lowing the template. D . Tightening the rod adjusts to fit work piece be- tween the clamps holding it. E . Template tracer arm has a special roller bearing that fits the edge of the template which must be at least 1 ⁄ 4 " thick. As X platform moves to right, tem- plate tracer bearing follows edge of template, guiding Y carriage in moving saw blade to cut desired shape. F . Template for egg shaped work piece shown clamped in place on template table. Template repre- sents one-half of desired shape of finished piece.
