Having taken a break from trying to learn woodworking, I'm hoping to learn some new skills over the holidays, weather permitting. My interest in woodworking was inspired by Norm. This video is one of the best introductions to routers I've seen, so I highly recommend it to other beginners. What frustrates me about it, though, is the dado jig. He cuts the dado, and the shelf fits perfectly. In my limited experience, it's next to impossible to get a bit to fit the thickness of a shelf perfectly. I can only assume that he either milled the shelf to match the bit, or he got lucky. My guess is that for most people using this jig, it would be better to use a 1/2" bit and to cut the dado in two operations, shifting the jig from one side of the 3/4" dado to the other. Your comments and suggestions are welcome.
