January, 1919. R1/G4119. RE CAR CONNECTING ROD. It is thought that the shorter pattern is a decided advantage to the pistons. We must urge Mr. Hives to ascertain if this shews any disadvantage as regards vibration. If no disadvantage can be detected, it will be safe to order the shorter rods. We think it is absolutely necessary to put off ordering forgings until the test is made. R.{Sir Henry Royce} | ||
