With all of the boards cut to the proper lengths, the next step in these free rustic pot rack plans is to rip the french cleat. For this task, you'll need a table saw with the blade tipped to a 45-degree angle. Set the saw's fence so that you're cutting directly through the center of the board, leaving two identically sized boards, each with a 45-degree bevel on one side (as shown in the image above).
When cutting a thick board with a steep bevel such as is required by this step, use a sharp saw blade, with the blade height no more than about 1/4-inch higher than the top of the board. Do not force the board through the blade excessively, but allow the speed of the cutting dictate how quickly you should move the board forward. Also, be sure to stand a bit to the side of the board (rather than directly behind it) so that you're not struck by the board in the event of a kickback. Finally, hold the board firmly against the table top and the fence to keep the board from riding up the blade.
When you're ready to proceed with the cut, rip the 34-1/2 inch long piece of 2x6 through the center as shown.
