This is my pattern imbedded in a mixture of sand, fireclay and plaster. I am planning to pour aluminum over this, remove the plaster mix and then pour the other side of the pattern. I'll let you know how it turns out!
Here are the two halves of the pattern. I had trouble with moisture in the plaster so I recast it in greensand only. Then I cast the second half on the first casting. The second casting turned out much better I believe because the pattern was still warm. The patterns will not give a very good final piece, but will let me at least try out my injecting machine...as soon as it is ready to go.

Machine set up
From here on down, is not related to metal casting very much...It is my efforts in setting up a plastic injecting machine and making a pattern for the machine.
This is the final machine set up with the heater band and controller installed. If you would like to see more on this, click here.
