While we were moving, the locating arms of the Leigh jig were damaged. (Why do manufacturers insist on cutting corners on the most integral and delicate parts? They are needed to remain square to the jig yet they stick out 6″ from the main body of the jig, and it is made out of pot metal.) With deadlines looming and all the North Bennet Street School moxie I could muster, I decide for a mix of hand and machine work on the dovetails that hold the case of the low Shaker side board that will ultimately be used as a TV stand.

First I cut the pins of the half-blind dovetails by hand.

Hand-cut pins

In this picture you an also see how I laminated up the sides of the case. The outside is a resawn panel from the flitch that I bought from Berkshire Products for this client that is book-matched and the inside is shop-made quarter-sawn cherry. (More on that at a later date.)

And then switched to the router to hog out most of the material.

Router Set-Up

I clamped the two sides together with a board on top so that board and other side would act like a stop while routing so I would not rout too deep into the pin board. This made the process go quickly. All I had to adjust between passes was the depth of cut of the router bit.

Router Bit

Because the router bit does not cut a flat face, I decided to do multiple passes to make the clean-up of the bottom of the tail socket dovetail joint easier. This is avoided when using the jig because the tails are sloped to match the bottom of the pin board, but when hand cutting and chopping the pins you need a flat bottom of the tail socket. Also, by cutting in lighter passes, it was easier to come close to my initial saw cuts without the fear of the router bit pulling into the keeper side of the pin.

Below is the sequence of cuts that I made.

I left about 1/32″ to pair along the face and checks of the pin board. It was quick work to clean up these cuts with a chisel.

Paring the Cheek of the Pins.

Pins Are Paired

Whenever dovetails are visible I take the time to cut them by hand, as there is a certain quality to dovetails that are cut well by hand. Since these dovetails are not visible once the top is on or unless someone is on the ground looking up at the piece, this was an expedient way to cut these dovetails.

A secondary challenge in the cutting of this joint was cutting and paring the tail boards that are about 6′ long. I ended up clamping them to the pallet racks that we use for storing our sheet goods and standing on a step stool.

One of the things I love about furniture making is while there are some standard practices, there is not “one way” to build a piece. Each piece has unique challenges and solutions, and each time you build a piece of furniture you are learning new techniques and strategies for common problems and adding to your knowledge base.
