When I started the selection process, I found those templates that all used one dovetail cutter — the 1/2" 14o dovetail bit.     The template page specifies the "approx. depth of cut" and the"spacing to set depth of cut." These are important in setting the router bit height with the accuracy needed to make really tight dovetail joints.   I use the Incra Depth Gauge to set the initial router height to the "approximate depth of cut" as detailed on the template page — 1/4".       While this can set the bit height very well, I will use the Incra method to test this depth of cut. After all, this height will directly effect the fit of the dovetail joint.   The first step, in this test, is to set the fence so that 1/2 the bit is showing and cut two pieces of scrap stock.     Then I move the fence to read 7/8" — that was listed as "spacing to set depth of cut." I cut both pieces at this setting.       Lastly, I fit the two cut pieces together. They fit exactly so my router bit height is right where it should be. [Note: I purposely raised one of the pieces slightly, to cast a shadow...otherwise the fit was so exact, you wouldn't see the fit.]    I next set the fence to visually center the bit on the work piece. This is a simple matter of marking the approximate center mark, moving the fence so that the bit is centered on the mark,  then running the piece over the cutter...reversing the piece and cutting it again.  Then, I adjust the fence so that the bit is in the center of the groove. There are certainly many centering devices available,  but this method takes only a second and is quite accurate.    With the center position known, I move the template so that the cursor is over 9B, the recommended centering point.    I now start the actual dovetailing by running a shallow rabbet on both ends of each of the side pieces. The template shows the approximate depth that the rabbet should be.      I have clamped four sides together for doing two drawers at a time. I move the fence so that the first cut is positioned...and make the cut. A few minutes later, I have cut all the tails on the sides of all four drawers. Now it is time to cut the pins on the fronts and backs.    I start by placing the Incra Stop on the outfeed side of the fence with the stop almost touching the bit. Here I am making a first cut to test the depth of the stop.       While you make the cuts on one board at a time, this process still moves along rapidly. It has been just a few minutes, and I have made all the "B" cuts on all of the pieces.    I quickly test fit the drawers. They fit nicely with good, tight dovetails. I won't  assemble them yet—I need to cut the bottoms and then apply glue. I will make the other sizes first. Main Menu Previous Page Next Page
