In the past, we have demonstrated a technique for cutting a mitered edge on a board by angling the table saw blade into a wood auxiliary fence (photo below). Don’t use it. The cutoff piece will be thrown toward your body as you finish the cut unless you’re using a push block. Plus, the saw blade guard has to be removed to make this cut. Avoid the risk! Cut mitered edges on the left edge of the board (photo above). This way you need no auxiliary fence, no gymnastics to dodge cut off pieces, and the saw guard remains on the saw during the cut.
Don’t do this:
Instead, use the original auxiliary fence protector to do this:
You can use the original fence protector (photo above) when you need to cut rabbets on the edge of your workpiece.
