Screw advance box joint jig. See also: Version 2 of this jig I built my new screw advance box joint jig to allow very precise cutting of box joints in a whole stack of work pieces at once.
Rather than the traditional method of doing box joints, which involves indexing each finger off of the previous finger, this jig uses a screw to give absolute position to each finger in the joint. I had previously explored the idea of using a screw advance for box joints with my box joint jig and with my computerized table saw jig The jig consists of a sort of table saw sled, which has a metal bar mounted to the bottom of it for sliding in the table saw's slot.
