| BY.{R.W. Bailey - Chief Engineer} from R.{Sir Henry Royce} DA.{Bernard Day - Chassis Design} HS.{Lord Ernest Hives - Chair} c. to BJ. Wor.{Arthur Wormald - General Works Manager} PN.{Mr Northey} CWB. 48410 R1/M20.10.28. ROAD SPRINGS. X.7410 X.5410 X.8410 I quite agree that we must stop hollow rolling of spring plates. This is not our work, but is done to make it easy to give a good looking spring, though it is a fake, and also the springs should always be in gaiters. I quite agree that the surface should not be made defective by stamping on names and numbers unless a place and method can be found that is harmless. One thinks it possible to get a much truer surface if we hardened between blocks like a circular saw (RR. idea) All the plates of one thickness should have one curve if the curve were true. I am sure it would be wrong to cut the ends - they should be i.e. square, with rounded corners, and properly tempered in thickness. This gives the largest surface for the load at the ends of the plates. The plates could easily be held on a magnetic chuck and truly ground and polished. It would need some special plant, but the process could be made inexpensive, and the surface nearly perfect - (RR. idea.) R.{Sir Henry Royce} | ||
