ABSTRACT:
A circle cutting device for selectively rotatably retaining a workpiece in a jigsaw permits a user of the circle cutting device to cut accurate circles with the jigsaw. The circle cutting device includes an elongated track secured to the jigsaw, and further includes a housing having an upper portion slidably adjustably attached to the elongated track for location at a preselected position and a lower portion with a centrally located opening therein. A pin is positioned in the centrally located opening of the lower portion of the housing and extends a predetermined distance from the opening for selectively engaging a workpiece and maintaining the workpiece in a preselected position in relation to the jigsaw, thereby providing a pivot point for rotatably retaining the workpiece in the jigsaw so as to permit the user of the jigsaw to accurately cut circles from the workpiece. A spring is located within the housing between the upper shoulder portion of the housing and the thumbscrew, biasing the pin downwardly onto the workpiece and a pin is located in the lower portion of the housing for securing the pin within the housing at a predetermined distance.
