Festool Dominoes

Instructions

Step 1: make the fixture to hold a domino. I used some 12mm thich offcuts of hemlock from last weeks table build (plug!), cutting a 45 degree groove across the ends to make a 'vise' to hold the domino. The v grooves are 3.5mm deep, 7mm across and centred 4mm down from the edge, leaving 0.5mm on the edge to avoid sharpness. You could, optionally put a stop on the left to align the domino but I found a fingertim test enough to get it flush. The spacer is 17mm of plywood, which made a jaw width that was just a bit tight. I had planned to use another clamp to put pressure on the jaws but didn't need to. In fact, I was using a small pry bar to spread the jaws to get the dominoes in and out. Whatever! It worked. Step 2: make dominoes. I used a 1mm bit cutting to 1.5mm depth to make the lines across them iddle of the dominoes, being careful to get the Festool logo on the bottom. Then I used a 3mm bit to helix out the 4mm holes to a depth of 2mm. Caution: work through the numbers methodically. The hardest part of this project was keeping track of which numbers I was doing. Finally, pay the Festool tax for a mini systainer to keep them in. P.S. The day after posting this project, I made a little box for them using entirely on-tool design features and more off-cuts of hemlock.
