Small Metal Casting Furnace For Sale-60 lbs Bronze/Aluminum - $700 (Deland, Fl)

Casting | | | | | | | | |

Hello! I am selling this portable furnace built for bronze. brass, or aluminum casting. This will work for any metal with a melting point lower the 2500 degrees. The face of the interior is filled with 3000 degree refractory, then backed with 2600 degree. 3000 was use for the face to protect against the heat, but due to the fact that it is extremely heavy, the lighter 2600 degree refractory was used to fill out between the face and the furnace walls. The furnace comes equipped with a blower for delivering propane to the center. It also comes with a propane regulator... propane tank not included. I am also including a set of crucible lifting tongs and crucible shank as well as a crucible used with silicon bronze... it is a bilge shaped B20, as well. I can also throw in three skimmers used for bronze. You may be able to fit a larger crucible other then a B20, but the B20 is the only one to have been used so far. The shank is useable with up to a #30 crucible. The furnace is portable, built on cast aluminum wheels. There is a wide hole for charging the crucible with more metal, but a separate cover to keep the heat in when not charging. The total weight runs right around 300 lbs. This is a great economical choice for low-volume casting.


Should I let it go?

missing sprues

 I’m a newbie to lost wax casting.  My biggest problem is “missing sprues”.  As shown in the photo, one sprue was lost on this brass casting.  I have had similar problems on several occasions, resulting in incomplete castings.  This item was cast using vacuum assist.  It was cast in a 2 ½ x 3 flask.  I used Kerr Satin Cast for the investment material.  The flask temperature was 1100 degrees F and the pouring temperature was 2000 degrees F.  Other castings came out OK.   Help will be appreciated.  Thanks.Missing Sprues: I’m a newbie to lost wax casting. My biggest problem is “missing sprues”. As shown in the photo, one sprue was lost on this brass casting.

4:00am Burnout Thoughts

Up late again. In and out of the studio as I wait for the tumblers. Thinking about how happy I am that there is metal clay and PMC because it allows me to create in metal without having to wait to be able to afford all the accoutrements that go with lost wax casting, forging, etc., etc. as I continue to build my metalsmithing studio...


Help with bronze casting

Casting

Hello everyone. A few years ago I built a small furnace and played with the metal casting process. I tried both aluminum and bronze. I have not work with any of it in a while. I now have some peaces that I have sculpted and want to make some bronze casting. There is so much information out about the process its easy to get confused. I will be making rubber molds of my work and casting wax into them. I will then attach the proper runner bars, gating, and pouring sprue.

Further progress on the dog sculpture. Its been raining here all week AGAIN. However, today I was off work and the rain stopped, so I got myself set up to do the casting this morning. Below are pics of the results, but first some pics of the shell application.


Anyone used fiberglass mold to cast their wax model?

Casting | | | | | |

Is it possible to use a fiberglass mold to pour a wax? If not I suppose I'll have to pour a fiberglass model to make another mold from. Any suggestions or experience out there?


New bronze and steel sculpture

Casting | Fabrication | Welding | | | |

Here is the latest in casting and fabrication for my own personal work.  The base is fabricated plate weathering steel and the sculpture itself is cast and fabricated from silicon bronze. 

  Latest work 69 inches high by 42 wide.  The base is fabricated from plate weathering steel.  The sculpture is cast and fabricated silicon bronze.  It is a design concept for a fountain.  The sculpture is part of an on going series which explores natural earth processes such as erosion and tectonics.  Some of the series is 2d, though most of the series is sculpture in bronze, steel, wood and plaster.
