The snubber arms are cast in a three step process.

1.  The molten steel (~2900^oF) is poured into the assembled sand mold and allowed to cool and solidify in the mold.

2.  The  solidified casting is removed from the mold, shot blasted to remove surface sand, and then given a normalizing (1650F) heat- treatment.

3.  The gates and risers are torch cut off of the casting and the stubs are finish ground.

The casting is now ready for heat-treating.
