Making Your Own Clamp. Lost Foam Casting. Aluminum

I needed to use one more clamp for making one project, so I decided to make one out of aluminum.

Using foam cutting a pattern of a clamp and making a green sand mold/

Melting aluminum and start casting

When the mold becomes colder it's time to open it.

Drilling, taping and welding

The clamp is strong enough and works how it was planned.
