Saw the 2x4 side and end frame pieces and legs to length according to the cut list. To outline each leg's rounded-off corners, draw a line parallel to, and 1¾ inches below, the top edge; measure and mark the center of that line. Use that mark as the pivot for your compass, set at a 1¾-inch radius, and draw a half-circle that intersects with the top edge. Now cut along that line with the jigsaw. Drill a hole through your compass pivot with a ¼-inch bit. Repeat for all legs.
