Once again, Rob Gallerani demonstrated his inquisitive and creative mind by demonstrating how to make a sand mold and subsequent casting. He simultaneously cast an aluminum handle to a small throwing knife and in the same mold a finely detailed wood engraving in which he added some real garnet from the Adirondacks. Rob clearly explained all of the steps involved, the costs, the retail material resources and the most common issues which often unexpectedly come up. Terrific demonstration which took over an hour plus but well worth every minute. The finished items were very cool. Nice Job, Rob.
