RE ROCKER LEVER ROLLER. Will you kindly instruct the experimental dept. to produce six sets of rollers for the above mechanism in ball bearing steel, that is, K.E.S.J.B.S. or a similar steel made by Firth's instead of the present material, namely, C.H.N.S. The object of the experiment is to try and overcome the scoring owing to which a number of rollers are scrapped on every engine during test. The above steel should apparently give us a universally harder surface and better results. I consider the parts should be made - one set used on experimental engine regularly - five sets used on production engine, which should be reported upon as to their condition after the endurance test.
