| 612 SECRET. WRAITH III SLIPPER FLYWHEEL. Referring to E {Mr Elliott - Chief Engineer} /Jnr. {Charles L. Jenner} 1/HP.30.4.37. in connection with the above. Apparently the greatest objection to drilling the from flywheel to locate the springs instead of using cap nuts shown on Ld.5492 is that Mr. frequently has occasion to alter spring loads to suit individual engines before chassis can be passed off test, and it is understood that the design has been modified in order to simplify matters. If this is the case we should be inclined to agree that the screw cap scheme has its advantages, but we should be glad to receive your comments.
