ABSTRACT:
A workpiece supporting apparatus provides precise linear movement of an irregularly edged workpiece past the high speed cutting member of a power tool to produce a trimmed straight edge on the workpiece. A spacer, havng an enlongated keying member mating with a precision miter groove of the power tool, includes a precision miter groove oriented parallel to the miter groove of the tool and closer to the high speed cutting member. Securing means maintains the spacer rigidly but removably fixed to the power tool. The supporting apparatus includes an elongated keying member cooperating with the precision miter groove or guide member of the spacer to guide the workpiece past the cutting member. The elongated keying member has first and second workpiece engaging assemblies which may be adjustably positioned along the axis of the elongated keying member to accommodate various length workpieces. Each of the workpiece engaging assemblies includes conical point members mounted upon spindles for engaging an end of the workpiece and for providing rigid support therefor. As the workpiece supporting apparatus is manually moved past the cutting member, the precision miter groove of the spacer precisely guides the elongated keying member so that a straight, precise cut is produced on the irregularly edged workpiece.
