| BY3-P28.2.22. centd. - 2 - In regard to the question of grinding, there is no need to grind the plates on the springs made to our own designs anymore than those made to the edges of the top plate, which get considerably augmented stresses, due to torsional effects etc., should be ground, in order to clear away any slight roughnesses on the edge, which would tend to cause fatigue cracks to develop. 1804 BY. {R.W.
