Casting Furnace

What is a 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.

Completed Stuff

  • 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

Stuff to build

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

Other

  • 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
