Yes, further on this detour. First is the hand carving, mostly with a hacksaw blade, and spruing.

Then it’s packed in sand and molten aluminum is poured in.

This one turned out a bit rough, I need to add an investment coating and tune the sand.
Here’s a short flyaround of it: m6g_proto.mov

These are a spinoff project of the lost foam casting- sword hilts and pommels for the SCA. This batch of five will, hopefully, help raise a bit of money for a foam-cutting CNC setup.

In search of something to test out casting technology on, and not having a CNC machine to churn out foam marine-suit parts yet, we settled on Transformers logos.

First up was the Decepticons’. It was coated with an investment made of clay slurry to try to preserve the surface finish of the foam.

It turned out alright, if a bit porous.

Next was the Autobots’.

When this came steaming out of the sand, encrusted with burnt motor oil, it looked and smelled like grim interstellar war.

After a bit we got that down pat, so we shrunk it a bit, to belt buckle size..

And we also embedded stainless wire into it, to facilitate making it into a wearable belt.
