ABSTRACT:
A woodworking apparatus comprises a support table having a flat, circular table surface, a first power driven cutting tool mounted below the table surface having a spindle adapted to project upwardly through an orifice in the center of the table surface, a second power driven cutting tool mounted off-center from the first cutting tool below the table surface and having a spindle adapted to project upwardly through an orifice in the table surface, a guide fence mounted above said table surface on a chord thereof, means for adjusting said guide fence relative to said cutting tools radially of the circular table surface between a position substantially central of the table surface diametral thereof to a retracted chordal position; and means for adjusting said guide fence angularly about the table surface, whereby the effective distance between the two cutting tools can be selectively adjusted by radial and angular adjustment of the said guide fence.
The means for adjusting the guide fence radially comprises a rearward extension forward on the guide fence centrally thereof, said rearward extension having a radial slot, and said means for adjusting the guide fence angularly about the table surface comprises a bracket having attachment means for securing the bracket to the table surface, said bracket having a radial recess for receiving the said rearward extension for sliding radial travel therein. Means are provided for selectively locking the rearward extension in said radial recess for radial adjustment of the guide fence over the circular table surface.
The circular table surface preferably has a circular edge perimeter, the bracket is arcuate, and the attachment means secure the bracket to the table circular edge as a downwardly extending peripheral flange.
