How to Cut the Dovetails

In this lesson, I will show you how to cut the tails on a dovetail joint detailing everything from how to wield the saw, all the way through to chiselling the baselines.

Lesson Objectives

Now that you have some crisp and accurate marking out lines to follow, it’s now time to begin cutting them out. This is where things can begin going wrong so it’s really important to get some sawing practice completed beforehand. Make sure that you can consistently cut a square line across the endgrain of a piece of timber before working on the actual piece.

By the end of this lesson, you will have all four tail components cut out and ready to transfer onto the pin boards in the upcoming lessons.

When I first started woodworking in 2012, we were given a Gents Saw at Rycotewood to saw the dovetails. While I didn’t mind the ergonomics of the tool, the width of the kerf and the raggedness of the cut were disgusting! I really struggled to get the cut started and also achieve a clean finish.

As a result, I upgraded to the Veritas Dovetail Saw which saw me all the way through to 2019 (pardon the pun) and is what I now recommend to beginners. There are 2 version available; the 14tpi standard tooth or the 20tpi fine tooth. I would advise you to get the standard 14tpi saw as the 20tpi tends to clog up when cutting thicker material.

Another option for a dovetail saw is a Japanese Saw. These cut on the pull stroke and are often easier for beginners to use. If you live near a woodworking tool store, I would implore you to go and try both options before committing to one. 

The Katz-Moses Dovetail Guide

If you are looking for instant, accurate and clean results when dovetailing, look no further than a Katz-Moses Dovetail Guide. This little tool helps keep your cuts square and at the correct angle by guiding your saw through the cut.

It features 2 magnets that are magnetised to the side of the saw and can work on both sides of the tails simply by rotating it 180 degrees. In addition, you can also cut the pins with this guide, as well as the 90 degree shoulders!

Many people hold back when purchasing one of these as they have been convinced by other woodworkers that they are ‘cheating’. Last time I checked, woodworking is not a competition. You are perfectly justified in wanting instant and more importantly good results on timber that you have purchased!

Don’t be put off by people who try to steer you away from this tool. Despite being able to cut dovetails freehand, I often reach for my Katz-Moses guide when I just want to get the job done. As a result, much of my workshop furniture is dovetailed together simply because it’s so easy to do!

I find that this guide works best with the Gyokucho 372 Dozuki saw as it can cut slightly deeper than a standard Japanese Saw. This allows you to cut deeper into the material while using the guide.
