his part to use only stable "engineering" plastics for both
the coupler halves and the box<
Doing some work on a box the other day I found the center boss is not
centered. In fact it is open on one side from the casting process. All I
had were the same way. So much for accuracy.
I suspect the reason for the plastic on the box is that the coupler
halves are on the same sprue.
