can see the plaster has been poured, set up and frame removed.
The the next step is to add the sprue system, this enables
the wax to be removed and the molten metal to be poured in.
can also see the cup that I'll be pouring the molten aluminum
in after the burnout. Another flask has been made that will
incase this for the next pour of plaster. Although I've never
done a two step investment mold this worked beautifully. It
sped up the break out after the casting and enabled the delicate
first plaster pour to be more controlable.
