Homemade Spring Wagon Seat
Two ⁷⁄₈-in. boards, 12 in. wide, between which two 12-in. pieces of 2 by 4-in. wood are bolted, provide a strong spring seat for a wagon. The boards are cut to a suitable length, and the 2 by 4-in. pieces are set near the middle, and about 8 in. apart. This gives a spring seat at each end of the device.
