Step #3 was to cut the bottom off the 14.5 oz can.
Step #4 was to cut flaps in the #10 can.
Step #5 was to cut slits in the 14.5 oz can that runs horizontally through the other two cans. The piece on the left is a shelf to feed tinder and provide oxygen.
Step #6 was to cut a circle in a #10 can lid. It holds the insulation around the 28 oz can and allows the fire to escape.
Step #7 was to fit the 14.5 oz can through the #10 can and the 28 oz can.
Step #8 was to pack insulation between the #10 and 28 oz can, place the #10 lid and bend a few tabs over to hold the lid in place.
Step #9 was to place the shelf in the horizontal can. Tinder goes on the top, and oxygen flows through the bottom. The hole I cut in the #10 lid was too big, which is why you can see the insulation. I need to do a better of of cutting the tabs next time, but I think it turned out pretty well for my first try.
