| To Wor.{Arthur Wormald - General Works Manager} From Hs.{Lord Ernest Hives - Chair} x4027 Hs.{Lord Ernest Hives - Chair}9/MJ.28.2.33. x3993 PEREGRINE. Now that it has been agreed that the actual production of this car shall be put off for the time being we think advantage could be taken of this delay in order to reduce costs. It would be very useful if we could have a list of what the Works consider expensive items on this car. One of the economies we suggest trying out is to use a coarser pitch helical gear. At the present time we are using a very fine pitch and we imagine, as each tooth is ground, there would be a definite saving if we had a less number of teeth. Other makers are producing gears with a coarser pitch. The other point we should like to raise is that during my last visit to W.W. I showed R.{Sir Henry Royce} a sample Peregrine connecting rod in which the connecting rod had been drilled to supply oil from the big end to the little end bush, this is used instead of the oil pipe. The Americans say that it is cheaper to drill the rod than it is to have a separate pipe. R.{Sir Henry Royce} was quite pleased with the specimen and expects us to make use of this on future production. We understand, however, that special equipment will be needed to carry out this operation. We should like to know whether the Works wish to continue with the separate pipe or whether they would like the drilled rod. We think the delay in the production of Peregrine could be made profitable use of in trying to reduce the costs. Hs.{Lord Ernest Hives - Chair} | ||
