Have wanted to cast my own bottle opener for quite some time. I don't really trust zinc because of how brittle it is to make the mechanical aspect of the opener so I have decided to coat an existing bottle opener with the casting. Built this around a free moosehead bottle opener with wax. Sprued and vented as shown to the left. coated in plaster and burned out in a wood fire. I poured zinc heated in the same fire in a soup can into the mold. this is the first time I have had gotten good wax burnout and pour. Cut sprues with dremel metal cutting blades. May or may not go on to patina it.
