Stopped dovetails for case work
For me, a sharp cross cut saw, a saw guide block (beveled to the appropriate angle), several sharp chisels (one ground for making the angled stop cuts) and a router plane makes the task fairly straightforward.
That said, every time I find myself engaged in this particular job I experience some level of trepidation. Obviously, layout is critical. Ergo, I measure, check, re-measure, re-check, etc., etc. I tend to take a few practice cuts with the saw (in some scrap), just to make sure that I’m “keepin’ my elbow tucked in”. As the bottom surface of the dovetail is critical to a proper fit, I use the router plane to insure even depth.
It may come as a surprise, but my goal is to have a fit that can be assembled easily, not requiring the use of a mallet. If the joints are so tight that they must be driven together, there’s a very good possibility of bowing the case side (or breaking out the dovetail) and remember that there needs to be a little room for the glue.
Next time, leave your router in the cabinet and enjoy the reduced decibel level.
