Precision Mortising Jig

When a project calls for a lot of mortises, nothing beats the power of a mortising machine. The only drawback to a mortiser is that repositioning the workpiece to drill the overlapping “holes” can be a hassle. This sliding X-Y auxiliary table makes mortising a breeze. First, the long, steel hold-down and toggle clamp anchor the workpiece. Then just turn a hand wheel to move the large table from front to back to accurately position the mortise. Finally, turn another hand wheel to move the table side-to-side. The end result is a clean, straight mortise. Best of all, it only takes some simple hardware to accomplish these tasks. And it all adds up to one shop accessory you’ll wonder how you ever got along without.
