Sand Casting with Pattern Resin

Panic button lettering and design are made on a computer and created by exposing pattern resin to blacklight. The pattern is molded in petrobond sand and a casting is made. Visit www.granthams.com/Projects for more of my projects.

This flask is made of 3 x 4 inch tubular steel. The cope and drag are 1 1/2 inch, for a total height of 3 inches. The sides are 1 x 1 angle with a 1/4" pin on one side and a 5/16" pin on the other. The pins are different diameter to maintain register. The are bolts with the heads cut off and tapered. I have made flasks up to 6" x 9" x 8" high. You can also use aluminum. No welding is needed.

The flask is steel rectangle tubing. The sand is petrobond, a commercial product available from mifco.com

Hi grantham418,

I like the little hand muller in this video. What shape is the mixing blade and is there a sieve in the bottom?

Thanks.
