Casting Furnace

It's a container and heat source used to melt metal until it becomes a liquid and can be poured into a mold.

• Casting furnace (currently uses a #16 crucible, but can probably handle up to a #24)

• Burner assembly for Propane - 12vDC motor, 2“pipe fittings

• Rolling cart and wheels

• #16 crucible
• #16 crucible tongs (top grabbing)
• #16 single-man shenk
• Waste Oil/Diesel fuel system
• Ingot molds (for left over aluminum for recasting)
• Lid lifting mechanism/jack

• Furnace lid lifting armature (50% complete)
• Sand casting area (sandbox on wheels) dimensions TBD
• Scree rake

• Ideas comments, suggestions always appreciated

• Cutting the top 3” off of the 20galDrum for a lid using a plasma cutter

• Furnace shell, lid frame and #16 silicon carbide crucible

• Burner tube before casting the refractory material - I used Uniram 85ESS as the refractory - avail. from Carpernter Bros in MKE

• furnace housing and lid with refractory

• furnace refractory burn-in
