A
first article casting of the snubber arm showed that there was some warpage in the offset
section of
the arm that occurred during cooling.
The
solution to this was to add "tie rods" between the ends of the
two castings in the mold, as shown in the drawing.
These "tie
rods" constrained the two castings during cooling and prevented the
warpage that was seen in the first article.
