I see lots of complicated Dado Jigs for use with a router. Maybe I am too anal, but all I have used for years is a crossed pair of scraps, a different sized cut on eachside, with one pair of crossed scraps I can effectively have 4 different usable jigs, each for a different width cut. I first make the cut in the jig,then mark where I want the dado on the piece I am working on, line the cut up with the marks, clamp in place and make the cut. To me its so simple, but others go to great lengths to do the same thing with to me over complicated jigs. Am I over simplifing a complicated job?
