Domino Joinery Tool Accessories

The Domino tool doesn't always work well with small workpieces because they're hard to hold securely. Cuts into miters are especially troublesome. That's where this table, above, comes in, combining a clamping surface, a stationary fence, and a movable triangular guide to align workpieces for 45° and 90° joinery. You can also make custom guides for other angles. The Domino (only the DF 500) mounts to the table, and 6mm shims elevate it to center mortises in 3/4"-thick stock. Optional shims in 2mm, 4mm, and 8mm sizes (no. 05J1702) accommodate different offsets.

This table works perfectly for 90° joints, but 45° miters are fussier, requiring you to reposition the angled guide and hold-downs after cutting the mortises in half of the joints. Although the hold-downs work, we'd prefer quick-acting toggle clamps to speed up the process of clamping and unclamping each piece.

This accessory, above, clips onto the Domino fence (both models), allowing you to align narrow stock to the cutter. The fences adjust independently, so you can center or offset mortises in stock from 7/8" to 2-3/4" wide. It works well but requires clamping workpieces to a workbench. Standard with both models now, it was originally an optional accessory, so earlier buyers might not have one.

Festool, festoolusa.com no. LA-DF 500/700

This right-angle plate above, fits both Domino tools, providing a welcome stability when using the tool vertically. The BigFoot can be mounted flush with the folded-up fence, or offset in mounting slots. If you don't already have Festool's Support Bracket, get this one instead.

Who else routinely sands each solid-wood Domino tenon just a bit when they're a little too tight in the mortise? With this plate, above, you instead drive tenons through the mating slots with a mallet to shave just enough material to loosen the fit ever so slightly. Anyone who's done a dry fit with Domino tenons—and struggled to remove them for gluing—will appreciate this accessory.

Attach this oversize support plate, above, to your Domino to replace the fence and instantly improve the stability and support of the tool. The robust plate includes alignment markings for accuracy. The deluxe kit shown here (in inches; metric also available) comes with a variety of bushings to center mortises vertically, as well as outrigger extensions with flip-stops for making multiple, repeatable mortises along a workpiece's edge. (You can also buy a basic kit without the extensions for a lower price.)

Woodpeckers, woodpeck.com no. DF500-OBSI-18

This table, above, works like the Veritas version, but it accepts both Domino models. The spring-loaded mounting plate allows you to center mortises in stock vertically from 1/4" to 1-3/16". An adjustable guide fence aligns workpieces at 45° and 90° accurately and any angle in between (though there's no scale). The Mortise Match produces accurate joints easily and quickly, though it does require a substantial investment. You'll also need to supply your own clamps—an added expense—but the slotted table accepts most clamps suitable for T-track. Again, we'd opt for quick-acting toggle clamps.
