==Operation==
*Start burnout process for flask
*clamp machine to sturdy table
*place chipboard box over machine (box currently (7/2015) located on top of lockers near back door)
*wind machine counter clockwise for several turns
*while holding wound machine, lift shiny metal bar upward and gently rest the swing arm against it
**Pressure from swing arm will hold shiny bar in place
*retract crucible tray (the metal bit that moves back and forth along the centrifugal arm axis)
*start heating metal in separate crucible in a safe, nearby location. Preferably surrounded by firebrick
*remove flask from burnout oven
*place appropriately sized sheet metal support ring over heated investment flask
**we have one for our wider flasks and one for the narrow flasks. Both are located with the flasks, crucibles, and casting machine
*load flask and support ring onto the swinging arm
*push crucible tray up against back of heated flask until snug
*load crucible with molten metal into crucible tray. Keep under torch as much as possible to prevent oxidation.
**Try not to torch the casting machine
*pull counterweight slightly counterclockwise to release shiny metal bar
*release counterweight and GET YOUR ARM OUT OF THE WAY
*allow spinning arm to come to a complete stop before removing crucible/investment flask
*dunk investment flask into water bucket to disintegrate investment
*admire prize
* better mounting for tables
* better mounting for tables
* document the box you put around it to avoid splashy metal
* document the box you put around it to avoid splashy metal
**Current box is kind of crappy, but works fine
