So there’s this old woodworking adage, “Measure twice, cut once.” That’s super. I did all my maths and then did them again and decided that the rabbet in the back of the bookshelves to accept the back sheet of plywood should be 3/8″ X 1/4″. That would allow the plywood to be recessed into the case by 1/8″ and fit snugly to make sure the case was square and did not rack. So I set up my saw with the dado cutter to do 1/4″ wide cut, 3/8″ deep and ran the pieces through. Oops. That should have been 3/8″ wide and 1/4″ deep. See illustration. I think I know what I’m going to do to fix this without buying new plywood but man, what a pain in the ass. I would propose an amendment to the rule to be “Measure twice, cut once, don’t be a dumbass” but I think that last part is supposed to be understood.
