re: Another way to Make Perfect Fitting Dados without a KerfMaker

To be honest, I only use one of the two tablesaw methods I mention or once in a great while a router if I have many dados to do. 
But far and away and most of the time I do my dados by hand tools. I can use my backsaw, chisel and router plane and have it done by the time power tool users load their blades or bits and have it set up. Just sayin' 😉
