In the soundboard there is a 3" hole with a metal "rose" (medallion-like thing) in it. To make this, I poured a disk of wax, carved a positive rose, cast plaster around it, baked the mold, melted the wax out of the plaster, then melted a mix of lead and tin and poured it into the mold. (Actually... I'm not 100% positive what the metal is. I used plumber's bar solder, and it had the "this product contains chemicals known to the state of California to cause cancer..." warning on it, so it really could be any mix of lead, tin, silver, antimony and copper. I was hoping to find 50-50 lead-tin.)
I haven't broken the mold off yet, as the metal is still hardening. But here are pics of the casting!
