Sliding dovetails are a great option when dealing with end grain joints, or with fixed shelves or dividers on a chest of drawers. I made a large sliding dovetail on the partition of the changing table I made some time ago (I used my old D4 jig, the predecessor to the D4R).

The D4R jig makes it simple and easy to create sliding dovetails:

1. Select the router bit and a suitable guide bushing
2. Route the dovetail slot – the board is clamped horizontally
3. Route the tail at the same bit depth, and with the same router bit – the board is clamped vertically

To fine-tune the fit, adjust the tail size by moving the finger assembly either forward or backward in small increments. It is possible to make adjustments as small as 0.001″ (one thousand of an inch!).
