I am currently trying to sculpt, and subsequently cast a sword handguard (see picture), I was going to sculpt it from wax and do a lost wax pewter cast of it. I also toyed with the idea of doing a lost foam cast from brass or aluminum. The problem is, I dont want to sculpt it and then destroy my sculpt if the pour doesn't come out ok. So what should I sculpt it out of, and what should I mold it out of ? I thought about making something with fimo clay, baking it and using it for sand casting, or maybe I should make a resin master? Too much information and I'm not sure which way to go. Any help would be appreciated.
