Progress (circa 2013)

Published by Douglas Slingerland on


This has been a long time in the making.  This has been a long time coming.  This is a culmination of all my research and effort.  From here, it only gets better.

I carved some models from wax.

 I casted them in plaster of paris with some play sand 1:1 ratio (by weight)

I cured the plaster in the oven for 4 hours at 250 degrees.

This allowed the wax to melt out and the cast to dry.

Afterwards, I heated the mold up in my foundry, to glowing red.

I headed up the aluminum to glowing orange.  A very satisfying color.

I poured, cooled for an hour, cracked the mold and found this bad boy.

This next cast is sand and plaster 1:1 ratio by volume.

I suspended them with toothpicks, adding a larger chunk of wax that will allow it to pour easier and give it a fluke to suck in aluminum as it cools.

These are wax carvings provided by a local artist.
