Tenoning Jigs

Cutting tenon cheeks horizontally with a stacked dado set can’t match the smooth cuts made when using a tenoning jig to hold the workpiece vertically (above). A tenoning jig registers in a miter slot, so it can’t wiggle side-to-side after you tweak the built-in bar adjusters to snug the fit. The five cast-iron jigs we tested look and act similarly and have the heft to help glide through cuts without vibration.

Overall grade: A

Subtle differences among such similar jigs add up to make this our favorite model. A push-button release helps this base adjust side-to-side easiest, and the most responsive microadjuster makes it a cinch to dial in a perfect-fitting tenon. It slides smoothly in the miter slot, and the large-diameter handles feel the most natural. The workpiece rear stop tilts only to 45°—all other test models extend 48–50°—but we rarely need more than 45°.

Rockler, no. 29840, $180

Overall grade: A–

Unlike the two vertical handles typical of a tenong jig, one of this jig’s handles mounts horizontally, so you grip it differently (though we found no advantage). We like that the miter bar relocates without disassembling the jig (see lower left photo, previous page).

Overall grade: B+

This bare-bones model won’t dazzle you, but it does everything a tenoning jig should do safely and accurately.

Overall grade: A–

Nearly identical to the Rockler jig, but we found the base plate more difficult to slide side-to-side when making coarse adjustments. 800-225-1153, woodcraft.com
