In a perfect world, you’d make all the cuts for same-width project parts at the same time. There are instances, however, when you need to set the rip fence for other cuts, and then must return to the original table saw setup. That’s when you need this jig. Its adjustable arms allow you to quickly reset your rip fence for two repeatable settings without fussy measuring and/or test-cutting. I mostly use the jig with my table saw, but it works just as well with a router table equipped with a miter gauge slot.
Build it as shown, making sure that the miter slot strip fits your saw.
To use the jig, set your rip fence, then position the jig into the miter slot, loosen the wing nut, and slide one of the wood arms so that its end touches the fence. To use the second arm, rotate the jig end for end. For greater versatility, consider making one arm 12" long; the other, 18" long.
