How to build a heliostat parabolic reflector

Step 8 Finally flip it over and tada a parabolic reflector, now to turn it into a solar oven

eventually I hope to turn it into a tracking solar oven with drill head motors. a word on the coroplast plastic in these signs, to glue it u can flash it with a blow torch and use super glue, and hot glue works well to glue it together, the "rigid disk is just two pieces with the corrugations orthogonal glued with hot glue. Sorry no pix in operation, it's dark out.

Thank you!! I've been looking for a way to do this (easily) for three seasons now! And without figuring out the math! I'm just not built that way. There's this amazing spanish video on youtube that shows that you can cook anything in the cooker (fried, baked, boiled, canned, and even popcorn)! Enjoy: http://www.youtube.com/watch?v=9lvIJStLdYk
Hopefully I'll post my replica before September :)
