Introduction: A Sand Casting Demonstration
This is a demonstration on sand casting with aluminum. In this demo I make a pair of practice knifes with dull blades for martial arts. The best practice equipment actually resembles real weapons. Working with plastic practice knifes takes away from the realism.
Coming later is how to make a furnace, and how to make molding box.
We have a be nice policy.
Please be positive and constructive.
