Step 1
Set the table saw fence 3 inches from the blade, which is twice the width of a 2-by-2. Start the saw and cut a piece of plywood 3 inches wide using the fence as a guide. Turn the saw off. (Note: A 2-by-2 is dimensional lumber that measures 1 1/2 inches wide.)
Step 2
Set the 2-by-2 on the plywood with one end flush with the plywood end and the left edge of the plywood and the opposite end of the 2-by-2 flush with the right side of the plywood. Mark the edge of the 2-by-2 on the plywood and remove the 2-by-2.
Step 3
Apply double-sided tape to the plywood piece along the marked line. Remove the tape backing. Place the 2-by-2 on top of the tape, with the edge aligned with the marked line. Press the 2-by-2 firmly onto the tape.
Step 4
Place the plywood on the table saw with the right edge against the fence. Set the fence so the table saw blade aligns with the leading corner of the 2-by-2.
Step 5
Start the saw and feed the plywood and 2-by-2 through the blade while keeping the edge of the plywood against the fence. The plywood will have a straight cut, but the 2-by-2 will be cut in two diagonally between opposite corners.
