Flask and First Cast

This first image is of one of the two flasks I made yesterday. The top section is called a cope, the bottom section a drag.



This image shows the cope seperated from the drag. The keying is used to re-align the two sections after removing the pattern from the flask.



The larger flask is 12" x 8". The smaller is 8" x 6" if memory serves me. They are both made from MDF. I sprayed the inside with a clear coat of paint before using. After the first cast, there was no evidence of the clear coat left. I suppose I was skip the clear coat in the future.



The saw horse along with the board leaning on it act as a wind screen. The foundry is located in the center, a metal pail to the right acts as a receptical fro dross. The pail contains a stainless steel spoon used for removing the dross from the crucible. To the far left is the coal bin, not currently in flame. The air hose feeds oxygen to the fire. It is typically set at about 20 to 25 PSI.
