The Solar Baby (named by Aunt Phylly) is a small solar oven made of recycled materials. It reaches 325 degrees in the winter Arizona sun. All measurements are determined by the size glass that you find. Tempered glass is recomended as it gets very hot. You can build this bigger, I had one that would cook a whole chicken in 2 hrs.
For this oven I found an 8x10 picture frame for 99 cents at Goodwill. The wood from a remodel we walked by. Had to buy hinges and latches from a recycle store. 2 big popcorn cans, fiberglass insulation from a construction site. Aluminum paint roller tray grate 1.99 at walmart, metal coat hanger, Alumimum foil. Most of the work was done with a dremel tool and saber saw. 1/2 the outside length determines the radius of the outside dremel cut. another cut 3/4 inch inside for the inside tin. Build the stand 1/2 inch wider than the curved oven. Elmers glue for the aluminum foil ends
The reflectors are 1/8 plywood set at a 60 degree angle. Beveled edged for a good Gorrilla Glue seam. Glued on aluminum foil. Glued the reflectors to picture frame. Used 2 removable pin hinges and 2 latches between wood picture frame and curved box.
