I am cutting square bench dog holes into the top of my workbench by running dados along one face of several boards at a 3 degree angle. Soimagine the boards standing on edge and one board will have the dado and the board next to it will not but serves as the 4th wall to the dado'ed board when they are all glued together standing on edge. The alternate boards will be dado'ed at a 3 degree angle to form the square benchdogs.
To achieve this, according to the instructions (essential workbench, FWW) I have to place a wedge that is 3 degrees on my crosscut sled against the fence and just behind the bench top pieces i will dado so that it holds those pieces at a three degree angle relative to the crosscut fence.
I do not know how to make the wedge - the crosscut sled is only about 21 inches across and the wedge will look like a board that is flat against the crosscut fence but tapered. I am guessing I just cut a taper on the board. Is that how I do it? I also not sure how to cut to achieve the 3 degree angle - some geometry solution I suppose I need.
