Hi. Long time lurker and reader of the forum. Just finished building a beer keg furnace, done my dry out and first cast of aluminum ingots while waiting on sand and supplies. Built both LPG and siphon jet waste oil burner but only used LPG as I'm still making some bits on the supply side of the waste oil setup. Only plan to cast aluminium and copper alloys for now as a means to support my other projects. Avoiding the cost of stock for machining and making the best of available scrap in the process. Otherwise setting up for lost foam, green sand, sodium silica sand and basic investment(lost wax and PLA) casting. So have plans for an electric burn out kiln and other bits on the way along with 3D printer and CNC router some of which will also support some of my other fabricating needs.
