I've built several using a 5-gallon steel containers for paint or thinner. Make a refractory liner using castable refractory about 2-inches thick on sides and floor. Cast a separate cover 2-inches thick with 2-inch hole in the middle. Weld or braze a 1-1/2 inch pipe coupling near the bottom, at a 45 deg tangent. Pipe to a tee with side entrance for gas supply and straight length of pipe from old domestic vacuum cleaner (cylindrical tank type). Throw a lighted piece of paper soaked in kerosene in the furnace, turn on the gas and whummph! it's lit. Turn on air supply regulated with a 120 volt dimmer switch for speed control. Adjust air/fuel ratio for maximum noise and clear blue flame. Put 1/2 brick on furnace floor on which to set crucible. Fill crucible with scrap aluminum or brass; 20 minutes ready to pour. Best to work outside; wear safety glasses and gloves. Need lifting tongs to pull crucible vertically out of furnace. Measure temp with thermocouple probe and digital reading meter. Be careful. Keep visitors at a safe distance. -:) Dave
