Of all the specialized table saw techniques I use, the one I probably turn to most often is cutting clean, accurate tenons with a dado blade. I’ve found that no other method gives me the same high-quality results in a comparable time. Best of all, the setup is easy and the technique can be mastered quickly. Essentially, a wide, stack dado blade does the hard work of removing the waste from the tenon cheeks and shoulders. Carefully adjusting the height of the blade is what gives you a snug fit to the mortise. The workpiece is fed across the dado blade using an auxiliary fence attached to the miter gauge. This gives you firm, easy control and results in clean, square shoulders. Finally, the rip fence is used as an end stop to accurately gauge the length of the tenons.
