Now that the drawer front is complete, it’s time to work on the sides. Trace the template onto the sides.
I use a scroll saw to cut this but small band saw blade or coping saw would work. Once the sides are sawed, glue the drawers together.
Once the drawers are dry, setup a plunge router with a 3/4” collar and a 1/4” drill bit. I ground the point to a very flat angle (mimic a router bit) and the side flutes slightly just for use in the router (since dowel rods are typically slightly under-size).
Now re-install the template and use the router (set on a slow speed) as a drill press and drill the dowel holes.
Glue and insert dowels into the holes & trim with saw or chisel & your done.
I have had friends look at dovetails and not make a single comment (not knowing how much work is involved). None of them can help but say “How did you do that?” when they see this joint.
And I can’t bring myself to tell them that it’s actually easier to do than the dovetails.
