Getting the Most From the Festool Domino Machine Text and Photos by Jerry Work For many woodworkers the construction of a butterfly leaf dining table like the small one shown here is considered a rite of passage because it is very difficult to do correctly.

How should we describe this innova- tive tool? Early in the U.S. introduction planning I was asked by Festool USA how I thought the machine should be de- scribed. Because I had lots of experi- ence with loose tenon joinery using the three dimensional sliding table on my industrial slot mortising machine, I first...

The Domino Body This sequence of photos shows how the body and fence can easily be separated by simply raising the lock tab as shown here. The wrench used to change cutters The fence will start to slide off the body as shown in the photos left and above exposing the rotating and oscillating cut- ter (red arrow).

The stop block is marked to center the bit on work pieces 16, 20, 22, 25, 28, 36 and 40mm thick. You can also simply use the height scale to set the fence any distance you want it to be above the horizontal cen- terline of the bit within the range of 7mm to 30mm.

There are only six ways you can join two pieces of wood together. I will refer to the surfaces of a board as the faces (the wide flat top and bottom of the board), the edges (the sides of the board) and the ends. Boards can be joined: 1) edge-to-edge Do that on both boards.

and lower side frame members and to hold the leg stretchers. Since those frame members are oriented with their wide face up and down (where the front and rear frame members are ori- ented with their narrow edge up and down) we need to cut those mortises in a vertical, rather than horizontal orientation as shown below.
Page 41
photos below. Here is the locating of the leg stretcher mortises. With both sides of the leg curved you need the cut off piece to get a reference. Be sure to align the cut off pieces in the same place up and down on the leg so the relative saw kerf is the same on all four legs.

Now let’s construct the rail, stile and ma- ple burl back panel. The doors will be done the same way. We saw earlier how I now use Domino M&T joints cut inside the tongue and groove joints of the rail and stile components to both reinforce these joints and to make them self- aligning.

smaller in diameter than the width of the sliding door tracks machined in the front upper and lower frame members. I cut the length of the tenon so the end of the pin would be flush with the bottom or top surface of the door when it was fully in- serted into the 10mm mortise.

The only thing left to do is add stop blocks to the inside of the skirts and the inside of the frame to limit how far the two top plates can be retracted. These are not absolutely necessary, but they do help the ergonomics of the table.
