Step 4: Cut Each End of the 17" pieces on a 60 Degree Angle
After cutting the 6 pieces, now cut each end on a 60 degree angle
A. Adjust miter saw from cutting at 90 degrees from the fence to 30 degrees.
B. With the board in your left hand place end of board on cut line, so that edge that is furthest away (against the fence) is at the cut line.
C. Once again, without turning the saw on. Verify that you are cutting a triangle off the end of your 17”board.
D. Rotate the board to the other straight end. Line up the saw as before and make a similar cut, creating a trapezoid shape.
