Since the topic of oven's has come up, I thought I'd add my 2 cents.     (You need to Login or Register is to a series of pictures taken of a reflector oven design.  I can not specifically say where the design originated, but I got a copy of the plans from QPassage last year.  I crafted a copy from the plans and used it last year on my May Quetico trip.  Over the course of my 14 day trip, I made brownies, cornbread, biscuits, banana nut muffins, and apple cobbler.  After experimenting with the brownies (first item cooked), all other items came out perfect.  The oven cooks hotter than expected.

The construction I used involved 0.025" aluminum sheets (which I acquired from Lowes).  Much of the cutting was accomplished using metal shears. The construction does not involve any fasteners--just tabs in slots.  The slots were cut using a jig saw.  I found the pieces bind together better if you are not too careful cutting the slots and make them slightly irregular rather than perfectly straight.  The food rack, on which the pan sits, is metal skewers which are inserted in equally spaced holes drilled in each side.  

Not shown here, but I also made up a rigid internal rack which can be bolted to the two side pieced.  This makes it possible to remove the bottom panel and use a stove (rather than a fire) as the heat source.  I also used the rack (with metal skewers inserted) for my fire grill when not in use with the reflector oven.

The field test revealed that access to items while cooking is a bit of a problem since you reach over the fire to check and adjust the pan.  To solve this problem, I re-crafted the smaller back panel to allow a "lift-out" section so that the pan and contents can be checked from the rear.  This adaptation has not yet been field tested, but I have every confidence it will work just fine.  (Also not shown, is a small metal thermometer that is use to guage heat.  It was difficult to see from the front, so the back panel adaptation should also assist with getting an accurate reading.)

All oven items are essentially flat and fit into a zip up pouch (design more for papers than an oven) for transport purposes.
