| E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer} HS.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} X8100 R5/M21.1.28. RE. DYNAMO DRIVE. LeC. 2501 X. 8100 Owing to pressure of work and anxiety to get the above on the road, would it not be better to let the serrated drive do for the present. Flexible steel plate drive could be internal, and probably is the quickest. I think two external Hardy flexible couplings will take too long to design and make perfectly. R.{Sir Henry Royce} | ||
