Stove Part II: Cardboard Model

The next step in our stove-making process was to make a cardboard model of our design. This part of the process allowed us to really critique and change our design. It also helped us learn how to measure and cut material effectively and precisely. It is surprisingly hard to cut a piece of material into a square...let alone into a trapezoid!

We secured the cardboard together with duct tape in the model, which was convenient at the time, but also gave us a bit of a false sense of confidence in creating hinges and connecting pieces of material. It is much much easier to connect everything with duct tape rather than with hinges and rivets. Nevertheless, we cranked out a successful model.

Throughout the time we were working on this stove, we didn't really assign each other specific roles. Each of us really just worked on whatever needed to be worked on. We each realized what our strengths were, and I think we played off of those a bit in coordinating our teamwork.

Below are some pictures of the making of our cardboard model:


Above is a picture of the front of our stove, with the flap for air flow clearly visible.


And above is a picture of the finished base of our stove. After building this base we decided it would be a good idea to add shelves to the sides to allow for varying levels of heat. We made a tray for the charcoal to rest on, and three shelf levels to allow for low, medium, and high heat. 



Above is a picture of the side of the model, with the placement of the shelves drawn on the outside.


And above see a picture of the tray at the medium heat-level setting.



Above see the top of the stove. The surface that will be put on top of this trapezoid-shape will be where the pot goes. 


And here is the chimney!


Finally, here is the front of the finished model! I was really happy with how this turned out. It was almost even evenly-shaped, which is surprisingly hard to accomplish. 

This part of the stove-making process made me a more flexible builder. At first, I was resistant to changing our design, but in making the cardboard model I learned that you have to be really willing to change everything is something's not working. More iterations of the design = success!

....and on to Part III....dealing with aluminum!
