  1. Step 4: Add a hole to connect the air supply. Drill a hole in one side of your metal basin to connect your air supply to your steel pipe. Insert the pipe so that a length of about 6 inches extends from the hole. This is your tuyere where the air source will add oxygen to your forge.

  2. The basics of heat and combustion are essential in understanding blacksmithing forges and furnaces. Combustion processes, which involve the reaction between a fuel source and an oxidizer, release heat that is crucial for heating metal in these specialized environments. Heat sources such as coal, charcoal, propane, or natural gas are commonly ...

  3. Heating metal to a working temperature is much easier than making metal molten. You can make weak metals (such as copper or tin) malleable in a random wood fire. Iron takes a bit more, you need to create an “oven” with proper airflow to increase the temperature.
