bpfink - Sunday, March 24, 2013 - 8:35pmCasting | OT: Sandbox YAK Sculpture Gallery | The sectiuon of the vacumm cleaner feed to the gas to enter the furnace. This one melts 300 lb. bronze in about 70 minutes from cold imgot.
I do question the leaf blower only because I have gone through several and they are a cheap motors and found my last 3 unreliable for a good run. The air pressure they give is more than needed so I only hope you have a way to also jack it down via some divergent pass system when needed to do a flame adjustment. I melt way more at a time in a much bigger furnace and use a vacuum cleaner motor for the air. That then goes into a pipe with a large 3 inch diameter water shut off valve before it turns into the 90 degree angle run into the furnace where the gas is also added. That makes it possible to throw away some of the air pressure without taxing the blower motor or chocking the intake and making the blower motor run hotter.

This was one of my old melting furnaces good for aluminum. It was so large it would melt down an entire engine block and misc. scrap to pour a piece and then pour the rest into ingots for later use. The molds were set low in the sand pit in front of it and the metal was transferred via a steel rain gutter type trough strapped to the pouring lip and to the top of the investments cup area. I no longer use it and only kept the crucible when done. I still have one half that size but seldom use it either. It held about 800 lb aluminum per melt if needed. bpfink
bpfink - Tuesday, February 26, 2013 - 12:14pmCasting | OT: Sandbox YAK Sculpture Gallery | foundry schematic
Here is a top view schematic along with even some diameter sizes of the pipes I used. It was drawn up back about 1977 when I was laying out what I would be using to fit this burnout and pouring facility into the corner of the studio. The walls around it are poured concrete with earth bermed outside so no problem with fire dangers. In addition I found a dumpster load of metal perforated store shelves being thrown out so those also line the walls up higher. All the kilns and bars and pipes used are from scrap also. The kiln bodies are discarded 2000 gallon underground oil tanks (since they have become illegal in this area now) (fill with water before you flame cut them open or they could still explode) . The main kiln reaches 4 feet below the floor and is part of the sand pit and runs with a household oil burner set at .75 gallon / hr. tip into it's own ceramic fiber enclosure. Old steel road drain grates then make up the floor. The pipes are mostly from the dump and had been heavy duty swing sets and oddities. The retracting spring that pulls the two long arm dummy handle end is simply from a casement window and extends out about 3 feet when needed to pull the inner pipe back into the outer one. I needed this since the whole assembly is in the room corner and needed to collapse into itself. Maybe the rest of it will be self evident on the drawing. bpf
