type having a handle 66 pivoted to a base portion 68 and to an arm 70 which pivots downward as shown by the dashed arrow when the handle 66 is depressed as shown by its arrow at the distal end of the arm is an adjustable screw with a rubber tip 72 which contacts the surface of the stock when the screw is properly adjusted according to the thickness of the wood stock as shown in fig1 the holdown clamp 30 on the stationary corner section 28 is angled approximately 30 u00b0 with respect to the longitudinal axis of the base 10 the angling of the clamp is important because when tightened the clamp 30 not only draws the end of the wood stock against the corner section 28 but also draws the edge of the stock snugly back against the indexing edge 15 of the adjustable member 12 in the slot 12 then the second holdown clamp 74 on the corner section of the adjustable member is tightened and the wood stock in firmly clamped the elevational view of fig2 illustrates a piece of wood stock 62 firmly clamped in position by the two clamps 30 and 74 also illustrated but not forming a part of the invention is a typical quarter round shaper cutter 76 mounted on the shaper spindle 78 with a groove cutter 80 and a ball bearing pilot 82 in operation the very high speed spindle is first positioned so that the rotating pilot 82 is pressed against a rubber stall pad 84 mounted to the working edge of the moveable sub template this stops the rotation of the pilot then the pilot 82 is moved toward the left as shown.
