Step 5: Making the reflector cone

Now that you have your 8 reflectors cut out, you need to assemble them into a cone. To do so, I cut 16 pieces of 2*4's at a 67.5° angle long of approximately 20 cm each. I screwed them onto the reflectors being careful to align the beveled surface of each piece. Once the 16 guide pieces of wood are srewed, you now have a way to easily connect the reflectors to each other: you screw the guide pieces together from the side!
