| (2) To prevent this wear we think that no- thing but case-hardened steel faces should be used where-ever possible, the reason being that copper or brass or even soft steel will get impregnated with grit, and so act as a lap. I do not think that slight errors in the horizontal plane are of any importance but cer- tainly those which affect the alignment of the spring parallel to the frame in plan, are of the utmost im- portance, and if not corrected would be the cause of destructive wear and possible broken springs.
