Building Simple Charcoal Forges

Building two examples of quick and simple sideblast charcoal forges with found and reclaimed materials to demonstrate that lack of equipment and materials should not be a major obstacle.

Ways to improve and expand on these concepts include: mixing copious amounts of chopped straw or charcoal powder (6:2) into the clay to make it refractory, using high temperature kiln bricks, making the walls higher and longer, using the clay to narrow the tuyere to about 1sun/3cm right where it enters at the bottom side of the forge, putting a barrier up to protect the fuigo (and allowing a shorter pipe), allowing the clay to dry before lighting the forge, etc.

Making a Bamboo Scoop for Water Forging

Simple technology for pouring water on the anvil, takeno mizusashi (竹の水差し) made from a piece of bamboo.

Forging with a thin film of water on the anvil and hammer prevents forge scale or oxide from being hammered into the surface of the steel. The hot steel instantly vaporizes the water and the resulting steam explosion blows the scale off of the work, keeping it clean as it is worked. This type of bamboo scoop is a traditional style tool for evenly applying water to the surface of the anvil or the hot steel. Read more about the process of making one.
