RECEIVED PLATING OF ROAD SPRINGS. -------------------------- Referring to BY3/G.3.1.28, I ought to have emphasized the fact when speaking of valve springs that it was not my intention under any circumstances to make a practice of plating these pieces. I intended my remarks to convey the fact that if it was agreed by the Administration that there was a need or a definite advantage to be gained by plating the road springs, to my mind a very doubtful procedure, we should satisfy ourselves that we could control the plating operation in such a manner as to entirely eliminate the brittleness which admittedly by all authorities is set up during the operation in question. My reason for picking on the valve spring was that it was a relatively inexpensive item and had been intensively tested in connection with the special Condor spring I referred to, and therefore this item represents a ready method of checking our capacity to plate without brittleness.
