The Mortise Pal mortising jig and clamp system makes cutting out mortises up to 3-1⁄2" cleanly with your router.[
Mortise Pal’s new patent pending Mortise Pal plunge router mortising jig and loose tenon joinery system clamps to stock up to 3" thick to create mortises up to 3-1⁄2" long, created from six polycarbonate templates. You can also make mortises as small as 1/4" x 3/4". You can locate the mortises anywhere from 3/8" to 1-1⁄2" from the edge of your stock, with no shims or spacers. You can also use the Mortise Pal to make angled or compound angle joints. Chip evacuation slots allow for waste removal, and an all-metal clamping knob reduces the likelihood of breakage if the jig tumbles off your workbench. It works with standard 2-1⁄4hp plunge routers and sells for $169 in 2010.
