Episode 17. Summary – the Leigh D4R jig

This is final episode on the D4R jig. It shows the Technical Bulletins that are available to allow you to make inlaid dovetails, simple or compound angle corners, end-on-end dovetails, and shelf pin holes and notches.Please remember, this is a Leigh-produced video, not my own. I have permission from Leigh to use the videos on my blog.

In the next episode I will start publishing the video series on the Super Jigs (12″, 18″, and 24″ width dovetail jigs).

Episode 16. Sliding dovetails on the Leigh D4R jig

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!).

Disclaimer: This is a Leigh-produced video, not my own production. My thanks to Leigh Industries for allowing me to post the jig video series on my blog.

Episode 14. Through dovetails on the Leigh D4R dovetail jig


This episode shows in detail the procedures to make through dovetails on the Leigh D4R jig. The steps are very simple:

  1. Arrange the guide pin spacing
  2. Route the tails
  3. Route the pins

The variable pin spacing makes the D4R a very versatile dovetail jig, allowing an almost infinite arrangement of dovetail spacing. In addition, this capability also allows setting half pins near the edge of the boards, which I find a neat feature.

As many of you know already, I love to make boxes – and the predecessor, the D4, is my go-to dovetail jig, exclusively.

The two episodes that follow will show the procedures to make half-blind dovetails and sliding dovetails.
