Hi Dale, Good points. I will see if I can implement some of your suggestions. Thank you, Keith

It is drawn toward you usually using a board or other straight edge as a guide and it scrapes the waste out from between two parallel saw cuts. You just keep protruding the blade a little deeper every few passes until you hit the required depth. When cutting dados with a router and this is probably the very best way to do it because of the absolutely flat bottom and crisp edges there are many ways to do it. The way I have most usually done it is to clamp a straight edge to the work, not usually anything as thick as a 2 by 4 but maybe the factory edge of a length of three quarters inch plywood or even half inch plywood stock and following that with the edge of the router base plate. This is a little tricky to get an accurate measure because it is so far from the edge of the router bit. A better way to do this is to make a special purpose guide specific to the router and bit to be used. You take something thin like tempered hardboard or Masonite or quality thin quarter inch plywood wide enough to include over half the width of the router base plus the width of thicker straight edge material. Usually this would be about 4 inches for half the base plus two or more inches for the width of the straight edge. Glue and clamp maybe pin if you have some really small brads but what ever, you stick the straight edge over the thin wood along one edge and when secure run your router along the straight edge with the desired router bit to cut away any excess off from the thin board. Now you can measure easily, conveniently and accurately to the edge of the thin board to very accurately locate where the dado will get cut. You can sophisticate this further by fixing a right angle fence to the bottom edge to align it more easily at 90 degrees to the work you are cutting or other angles come to that. Depending on the power of the router, the size of the shaft of the bit and the width and depth of the cut you may select full depth cut and I often do so. Usually you want to go a little slower but if you are cutting a half inch wide dado to a quarter inch depth in anything but really hard wood should be no problem. Stacked dado head cutters in a saw leave a good flat bottom cut and slightly deeper blade cuts at each edge. Some believe this is superior providing some place for glue to be forced, others disagree. I have no opinion but a router is unlikely to cause any chipping which cutting blades will. To prevent chip-out at the end of router cuts you can clamp or otherwise force a bit of scrap material where the bit leaves the work piece so the cut is continued into the scrap. Not quite so reliable but which usually works well for me is to approach each end first. Work into it slowly then go to the other end and cut on through. In this way you never exit directly cutting through the edge. A bit of care entering with the direction of the turning cutter is required because the cutter will tend to pull the router away from the guiding edge but once you are into the cut a little more than the width of the cutter you can back out then begin your cut from the opposite end and that should avoid tear-out. It usually does for me. I think I covered all I know about your questions. Your router can be a wonderful tool and can even be used in place of a circular saw or table saw for accurately cutting and forming wonderful clean cuts using a guide as I described and cutting right on through the work. It is slower but no chipping and razor sharp crisp edges. Have fun.
