<p>[QUOTE=&quot;Desertau, post: 9842373, member: 86775&quot;]Back when I was in high school we had in addition to auto shop, metal shop, wood shop, jewelry making and ceramics. I learned a lot of skills I use often, using a lathe, welding, casting and polishing, sand casting in metal shop and lost wax in jewelry.</p><p><br /></p><p>the little furnace is made from garage scraps and leftovers from the ceramics studio. The sand casting molds, foundry sand and parting powder can be had on Amazon, they also sell inexpensive furnaces if you don’t want to make your own</p><p><br /></p><p>For flux 20 mule team borax works fine.</p><p><br /></p><p>still figuring a few things out, the second attempt was better but I overheated the brass trying to get a fluid pour, opening the furnace something called uninhibited chemical reaction had begun where the liquid brass had reached its ignition temperature. I’ve seen this a lot with car fires where magnesium and aluminum engine blocks start to burn… they are almost impossible to extinguish. I am also going to flip it in the mold and add a sprue to make sure the molten metal gets where I need it.</p><p>[ATTACH=full]492175[/ATTACH] [ATTACH=full]492176[/ATTACH]</p><p>I’ll take images of steps making the mold.[/QUOTE]</p><p><br /></p>
