Goals of Casting 101

  • Build the shell for a foundry/forge
  • Fill with refractory (wait a week or so for aggregate to set)
  • Plumb the propane hosiery
  • Weld and construct foundry tools (Tongs, pouring ring etc.)
  • Fabricate flasks and make mold construction tools
  • Teach basic (sand) mold making. (We can get as complex as you want on this one, especially if we have a Makerbot!)
  • Cast some things!

TODO List for Casting 101

  • Get Class Approved
  • Get approval for Forge/Foundry
  • Find Local Supplier of:
  • Acquire and move large/heavy objects to space:
    • Fireclay and Bentonite clay - pottery house probably
    • 1 Bag Perlite (Airy Potting soil addative (Vulcanite will not work . . .)) This will be huge and at least 10x more that we need. Anyone have a garden that needs the rest?
    • 1 bag of portland cement (Not concrete!)
    • One bag of regular sand
    • One bag of fine grit "ashtray" sand
    • 1 Small steel barrel (roughly the size of 4 gallon paint bucket or something slightly larger like a scrap water heater, scrap propane tank, medium steel trash can, or similar)
    • 15-20 feet of scrap steel bits (1/4-1/2 inch rod and misc. scrap bits)
    • Something largish to mix refractory in . . . (wheelbarrow?)

Day 1 - Refractory casting

Necessary tools:

  • Hose + Shovel + Trowels
  • Trashbags + Cardboard
  • Welder might be handy

We are roughly going to follow the directions found here, with several notable alterations to the size and wall-thickness: [1]
