As a result of an internship program between El Domo - Product Design Agency and Icam France in collaboration with PUCE University Ecuador, Sebastian Ache and Benjamin Castang have developed an open-source stove/oven/grill combination using a regular metal barrel.

We're proud to be able to offer you this easy-to-make, easy-to-use oven and grill project. The main objective was to respond to a primary and vital need: how to eat and cook when we have little or nothing. We wanted to offer a solution to the problems and difficulties faced by a number of people today on earth where access to a cooking system is difficult. After several weeks of research and design, we came up with the product you'll find below. It has been designed to be quick and easy to make, using very few raw materials that are readily available everywhere.

To understand the steps that follow, we need to explain how the oven works. The oven is made up of 3 distinct parts. The bottom part supplies heat to the other two compartments. The middle section is the oven. You have a door that allows you to open and close the oven, and you can place the dish to be cooked on the metal rods that serve as supports. Finally, the top section serves as a grill when you are already using the middle section as an oven. It is enclosed and keeps the heat in. The grill is placed on the metal rods. If you're not using the oven section, you can easily remove it and place the upper section directly on top of the lower section for maximum heat. What's more, you can use only the lower section to grill your food on the metal rods. Note that all the parts with metal rods can be used directly as a grill. I should also point out that the top part is also closed with a door and can be used as an additional oven for heating a second dish. It's up to you how you use it, depending on your needs!

If you're interested in this project, don't hesitate to build it and send us your feedback, which we'll be delighted to receive. You'll find all the details, explanations, and assembly instructions below.

Tools:

To make your Oven & Grill product, you'll need various tools and materials. These can be salvaged or bought specially for the occasion. The choice is yours. Here's the list of supplies:

• a 200L barrel
• screws
• 2 hinges
• more or less one meter of a metal T-bar
• 10 cm diameter cylindrical bars
• a metal saw
• a screwdriver
• angle grinder if you have one
• a welder, if you also own one

Step 1

Take the barrel and clean it thoroughly. Under no circumstances should there be any trace of anything that may have been there before once this is done. You need to cut it into three equal parts as shown in the diagram below. Make sure you cut in the right places and cut cleanly and neatly. This will be important for the rest of the process. To do this, use the hacksaw.

Step 2

You now need to cut each piece in a very precise pattern. The aim of this stage is to cut the holes that will accommodate the cylindrical reinforcements. To do this, you can drill the holes using a 10mm drill. Make sure your holes are straight and aligned so as not to interfere with other drilling. You can refer to the 3D diagram to find out where to make the holes. You can also look at the plan below. For information, on the bottom piece, you need 2 rows, one at the top and one at the bottom, on the middle piece, also two, and finally, on the top part, you only need one row of holes. These holes are for the reinforcements that will support and consolidate the shape of the barrel. Once your holes are drilled, you can now tackle the door on each piece. To do this, cut a rectangle with the dimensions given below. You can use a disc cutter or a hacksaw. Don't forget to keep the removed parts, as they will be used to make the door.Repeat the operation for all three parts of the barrel.

Step 3

This involves cutting the 10mm diameter metal bar and fitting each end into a hole. You need to do this for all three pieces...
