I made this bench-mounted cutoff fixture for a circular saw out of scrap materials in less than an hour, and it saved me the price of a saw protractor and a trip into town. It’s simply a pair of parallel rails, held in place by two crossbars. One of the crossbars doubles as a fence to guide the saw’s foot. I made the one shown in the drawing for 90° cuts, but it’s easy to nail the fence at some other angle.
The distance between the rails depends on the width of the stock being cut. I positioned them so I could use two wedges to keep the stock from slipping, giving me a free hand to catch the cutoffs. I made reference marks on the near rail so that I could mark the length needed for the next cut without using a tape measure each time.
