Yes, it is my method and yes it has worked for me for years. If you are making 30 same-sized kitchen drawers and you don’t like the mechanics of dovetail guides and router’s screams this could well be the method for you. I can make a hundred dovetailed sides using my guide and have them all interchange with the fronts I cut. I don’t do it for that reason though, I do it for speed and efficiency and to eliminate the need for individually laying out each one at a time. You still fit the dovetails to the drawer fronts and backs, but it works for both through and half lap dovetail joints. It’s also of value if you make a particular box size over and over as a line in a design.
Try at least one for size and see how you feel.
