  • How I built a quick and easy home made ball mill

    I needed a ball mill. So naturally I decided to build my own. Here it is in all it's bodged together glory. It doesn't look like much, but it works great, and it cost almost nothing to build. As a bonus, this ball mill can also be used as a rock tumbler, or a glass tumbler to make your own quot;sea glassquot; at home.
