This is Jack at his molding bench.

He built a large riddle that is on legs that he rubs the sand through.

|
|
This is his 30lb. crucible that is sitting in the bottom of his furnace.
|
|
|
|
Jack has consturcted a frame that is on tracks. It rolls up to the furnace and picks up the cricible. Then he rolls it back over the sand and flask.
|

|
Here is the long view of his furnace and pouring setup. The best I have ever seen.

Here is the casting of an antique gas engine muffler baffle.
|
|
|
|
It is a very thin casting so we provided lots of risers, gating and feeds.
|
|
|
|
It turned out great!
