==== Procedure ====
Cut plywood to 65“x 27”. This will be the base of the collector.<br># Cut two pieces of 2 x 4 to 65” in length. Then cut two more pieces of 2 x 4 to 23” inches in length. The four pieces of 2 x4 will be the sides of the collector.<br># Drill four two-inch holes, evenly spaced apart into one of the 27” piece of 2 x 4. This piece will be located at the front of collector where air will enter.<br># Drill three two-inch holes evenly spaced into the other 27” piece of 2 x 4. This piece will be located at the back of the collector where heated air will pass into the heating cabinet.<br># Cut 4 x 4 to make two pieces 10”. Then cut each 4 X 4 at a 45 degree angle so that the legs of the collector will be able to be flat on the ground when the collector is set against the cabinet. . These two pieces will be the front legs of the collector. <br># Screw the two cut pieces of 4 x 4 onto the plywood at either end which will result in the front of the collector.<br># Use a caulking gun with food grade sealer to line the whole perimeter of the plywood before screwing the 2 x 4 pieces to ensure better insulation.<br># Screw 2 x 4 pieces onto plywood, making sure to screw the 2 x 4 with 4 holes on the side with the legs. Then secure by screwing 2 x 4 together at the ends. This will now be the foundation of your collector.<br># Lay down a layer of Styrofoam (from coolers or tv boxes) to cover the base surface of the plywood. Tack down the Styrofoam into the wood so that it does not move. Next lay down insulation on top of the Styrofoam, covering the whole area inside the foundation. A blanket, wood chips, or other insulating material can be substituted for the Styrofoam and insulation.# Spray paint the sheet of copper with black paint. The black paint will help absorb as much heat as possible.<br># Once paint is dry, fit the copper into the foundation on top of the insulation. Then cover the 2 interior sides of the 2 x 4 with insulation. <br># Cut a rectangular piece of screen to fit the width and height of the 4 holes of the front 2 x 4. Staple the screen onto the inside of the 2 X 4. This will prevent insects from entering the collector.<br># Caulk food grade sealant on the outer perimeter of the 2 x 4 to ensure glazing will be sealed tightly onto foundation.<br># Lay 63” x 27” Glazing on top of collector foundation. Next screw the glazing onto the 2 x 4 to finish the construction of the solar collector.<br>
