STEP 3: ROUT A SLIDING DOVETAIL SLOT

For the smoothest results, you'll create your dovetail slot by making three passes. 1: The first pass with a 3/8" straight router bit to a depth of 3/16" 2: The second pass with your 3/8" straight router bit to a depth of 3/8" and 3: The third pass with a 1/2" dovetail bit to the bottom of the #2 cut you made with your 3/8" straight router bit (or a depth of 3/8")

Turn on your MARK 7 and set your speed between 9,500 RPM and 10,000 RPM (on Mark V models, set your speed to FAST or 5200 RPM). Hold the back edge of your stock securely against your fence, and use a 3/8" straight bit to make a 3/16" deep pass by moving your workpiece left-to-right AGAINST THE ROTATION OF THE BIT so the bit pushes the wood toward the fence and through your cut. Turn off your MARK 7, re-set your 3/8" straight bit for a 3/8" deep cut and make your second pass.

Turn off your MARK 7 -- change to your 1/2" dovetail bit -- set your depth-of cut to 3/8" (to the bottom of the groove made by the second pass you just made with your 3/8" straight bit) -- and make your dovetail pass.
