ABSTRACT:
A self-contained mortising jig is disclosed which enables adjustable positioning and sizing of a mortise and which enables the use of a router or other tool to form finish or shallow mortises for mounting hardware, such as flush bolts, hinges, strike plates, reinforcement plates, finish lock mortises in door edges and other hardware. The mortising jig can be quickly applied to and removed from a surface to be mortised, and the position of the jig can be quickly and accurately adjusted. The mortising jig also enables mortises to be made in the edge of a door which is either bevelled or not bevelled.
