Chris Becksvoort’s Favorite Dovetail Tricks

Learn five ways to increase accuracy and reduce the time it takes to execute hand-cut dovetails.

Synopsis: Pins first, or tails first? Either will do when cutting dovetails, says longtime woodworker Christian Becksvoort (who happens to be a tails-first guy). Becksvoort, who has cut thousands of dovetails in his years as a woodworker, shares his five favorite tips for making the job faster and easier, such as cutting two pieces at once, using alignment blocks and a graphite pencil for markup and fitting, and strategies for easier glue-ups.

Several years ago I contributed to an article, along with Tage Frid, that argued the merits of cutting pins or tails first (FWW #116). Frid prefers pins first; I’m a tails-first guy. But ultimately, as I tell my students, it matters little which part you cut first because once the joint goes together, no one can tell the difference.

Over the years I’ve been building furniture, I’ve cut thousands of dovetail joints by hand, and during that time I’ve developed a number of tricks to make the job faster and easier. These are my five favorites.

1. Cut two pieces at once. One of the reasons I think it’s more efficient to cut the tails first is that you need to lay out the dovetails on only one piece, then use those marks to cut the tails on two pieces at the same time. And when you transfer those longer layout lines across the end grain of two workpieces and use the lines to sight your saw, you get a more accurate cut. Also, when you cut two pieces at the same time, such as two drawer sides, the resulting joints match visually. So whether you are cutting case parts or drawer sides, lay out the tails, clamp the two workpieces together, and save yourself some time.

Mark the layout on the face of only one piece. Use a chisel to mark the cutouts where the pins will go, then use the same chisel to chop out the waste. — **Mark the layout on the face of only one piece.** Use a chisel to mark the cutouts where the pins will go, then use the same chisel to chop out the waste.

Make the tail cuts in both workpieces. By cutting the tails in both pieces at the same time, it’s actually easier to maintain the sawkerf at 90° to the face of the boards. — **Make the tail cuts in both workpieces.** By cutting the tails in both pieces at the same time, it’s actually easier to maintain the sawkerf at 90° to the face of the boards.

2. Use alignment blocks when marking drawer parts. Have you ever dovetailed a drawer, glued it up, fitted it to the opening, and found that everything looked great until you slid the drawer bottom in place and discovered that the front and side grooves weren’t aligned? I’ve done that, and learned from my mistake. Now I cut the bottom grooves first, using the tablesaw, before I lay out dovetails and cut and chop the tails on the side pieces. To transfer the tail cuts onto the drawer front, I use an alignment spacer made of a small block of hardwood (usually cherry). I keep a bunch of spacers on hand, about 1 in. wide by 2 in. long, machined to different thicknesses, and choose the one that fits best in the grooves I’ve just cut. The spacer should slide into the groove and stay put. I push it into the groove on the drawer front so that it projects about 1⁄4 in., and then place the drawer side onto the spacer, which makes the bottom grooves align perfectly. I mark the dovetail pins with a slim knife, finish cutting all of the joints, and voilà, all of the drawer pieces align perfectly when the bottoms are slid into place.

Spacers for alignment. Becksvoort keeps a small box of spacers handy. He records the thickness on each one (to three decimal points), and finds one that fits snugly into the grooves for a drawer bottom. — **Spacers for alignment.** Becksvoort keeps a small box of spacers handy.

The spacer registers the parts precisely. By locking the sides to the front (above) and back (below) with the bottom spacer, pins will mate with the tail cuts perfectly. Becksvoort uses cherry for most of his spacer blocks because it’s stable. — **The spacer registers the parts precisely.** By locking the sides to the front (above) and back (below) with the bottom spacer, pins will mate with the tail cuts perfectly.
