I decided to fabricate a two part sand casting mold. The mold is composed of two frames which will securely fit together to prevent any loss of material while casting. Rectangular steel beam was selected for the unification of shape.
Tj was generous enough to show me an old school sanding technique that was once passed down to him. Instead of sanding in a circular motion, he taught me sanding in a figure 8 motion reduces metal evenly all the way around the frame. Although this technique may take time, I'm sure its application will serve in multiple avenues.
