Abstract:
An alignment system mounted on a table saw which has a rotating spindle for carrying a circular saw blade, a table for supporting a workpiece with respect to the spindle, a miter slot in the table and a saw slot in the table to permit the saw blade to extend through the table, so that the alignment system permits alignment of the table with respect to the circular saw blade, comprising:an alignment plate, said alignment plate having at least one substantially flat surface, said alignment plate being substantially rectangular with first and second long edges and first and second short edges, said long edges joining said short edges at substantially right angles and at least first and second holes through said alignment plate, each of said first and second holes being away from the center of said alignment plate, one of said holes being opposite said first short edge and the other of said holes being opposite another edge, said short edge being sufficiently short and said plate being sufficiently thin and extending through the saw slot so that said alignment plate is mounted with one of said first and second holes on the spindle so that said surface of said alignment plate is a plane at a right angle to the axis of the spindle and both said short and long edges being sufficiently long so that a portion of said alignment plate extends up through the saw slot when said alignment plate has either of said first and second holes mounted on the spindle; and a measuring device for mounting on the table to measure the angularity of the table with respect to said substantially flat surface of said alignment plate and the angularity of the miter plate to said surface of said alignment plate so that the table can be adjusted to a known angle in both a direction normal to the table surface and parallel to the miter slot with respect to said surface, at least one edge of said alignment plate being substantially aligned with the table to enhance measurement accuracy.
