To build a sawhorse, set a mitre saw to a 17-degree angle, cut a top piece, trapezoid piece and legs and then put it all together. When putting the pieces together, use strong, long screws.
To create the top piece, run a 2-by-6 inch board through to form a trapezoid so that the base measures 5 1/2 inches. Cut the piece in half to make two sawhorses. Next, cut four pieces of wood into trapezoidal pieces, ensuring they have a 10-inch base. To make the legs, take 2-by-4-inch boards and cut out eight pieces that are 30 1/2 inches long. They must be parallelograms when in profile, and use four for each sawhorse.
Take four of the legs and notch out a one-inch piece about 5 inches from the top of the leg. One way to do this is to make a number of 17-degree slices into the top of each leg, and then use a chisel and hammer to remove the debris.
To put the sawhorse together, screw one side of each support into a leg. Lay the leg on the ground and place the top piece vertically, to ensure the spacing is right. If the spacing is off, it may not be a snug fit. After creating both sets, assemble the legs to the saw horse and screw the pieces into place before using.
