Your first goal is to find a (somewhat small) to make the cooking chamber.  To make the math simple here, we am going to assume you will find a box with identical side lengths.  What we mean by this is that where the box opens up, the length is equal to the width.  The depth should ideally be no more than the length or width. 
The reflector paddle is a simple trapezoid with the following special formula.  The small upper part of the trapezoid is the same as the width of your cooking chamber box.  The wider size of the trapezoid is 2.25 x [cook chamber width] and the height is 1.25 x [cook chamber width.  Using these simple multiplications, the reflector will scale up to whatever size you desire.  Additionally, it will effortlessly create the desired 32 degree angle talked about in the theory section. 
Get some foil and tape it at the back to the cardboard with the SHINY SIDE FACING OUT.  Try not to put too much tape on the surface of the reflector side.  You will need to repeat this 3 more times . Easy!
