Build and Attach the Outer Corral
Once again using lap joints, create an L-shaped outer frame or corral. The approximate dimensions are 4 feet high by 6 feet wide, with the lower leg of the L measuring approximately 2 to 2 1/2 feet. This inner frame will be attached to the outer frame legs. Clamp the outer frame to the legs at an approximately 10 degree angle. This angle will keep sheet goods leaning against the back of the cart.
