ABSTRACT:
A keying system for a miter joint with a work holder for engaging the outer surfaces of the boards when assembled. A flat planar tool guide is fixed to the work holder and has a slot that receives and guides a router tool to cut a slot through both boards triangularly shaped in its longitudinal direction and shaped in cross section as the cutting tool. Keys having a shape complementary to the slots in both directions are fixed in the slots to both decorate and support the joint.
