| To RHC.{R. H. Coverley - Production Engineer} from EFC. X8692 EFC3/T24.11.27. TUNGSTEN IGNITION CONTACT POINTS. LEC.2460. We have a note from Mr. Royce asking us to try both a thicker and a thinner "anvil" as he calls it, in the Lec.2460 scheme, of which you have recently made up three units for running on cars. The anvil is the support for the fixed or screw contact point. Those that we have had made up for the cars have been .064" thick, and we have an .080 thicker anvil now running on test. Would you please arrange to have one produced from .050" material, but in this case, owing to the thinness of the material for the screw thread for the point, I think it probably had better be bent double just where the screw point is to be carried. We are handing to Mr. Tooby a distributor head which will do for this purpose. EFC. | ||
