Briquette Making - Mold
The mold is another item in the Briquette Making Machine Components that needs to be fabricated. But it's easy enough to make with a hacksaw and a power drill. The mold is made of a standard 2-inch PVC pipe. You don't need the entire length of a pipe so it's very cost effective if you can find a scrap length, maybe from nearby construction sites. That way you can even source it for free.
The mold is the component that will form and shape the briquettes. In the briquette making process, you will be able to finish more briquettes if you have several of these molds.
