Step 7: Finish the cover's top

Place the cover's top upside down on a tarp. Turn the assembled cover onto it. Center the cover with the back edges flush; there should be a ½-inch overhang around the sides and the front. Mark the inside perimeter of the cover onto the top.

Cut three 1x scraps to fit in a loose U-shape inside the lines. Glue and screw the pieces to the underside of the top. Caulk all seams, fill the nail and screw holes with wood putty, sand, and paint the cover's exterior. Once it's dry, use a staple gun to attach the screening to the inside of the cover. Cut a piece of sheet metal to fit behind the radiator to help reflect heat into the room. Then place the cover over the radiator.
