Sand Casting at The MakerBarn

Clay McGovernMaking, Materials, News, Tools

The MakerBarn recently added the capability to cast non-ferrous metals. One of the simpler ways to cast metal is to use sand to make the mold. At the Barn we have Petrobond, a special sand mix for casting. This training video shows the making of a branding iron with “The MakerBarn” on it. First a pattern was cut from Corian using the CNC router. This pattern was used to make the sand mold. Scrap aluminum is then melted and poured into the mold.
