Suggestion to pause making helical gears for the 14-EX car and instead test a new motor with helical teeth on the 9-EX car for comparison.

| X7637 A C. EFC. BY/RD3/ML19.12.27. SEQUENCE STARTER. Re RHC{R. H. Coverley - Production Engineer}7/BE.14.12.27, if the helical gears have not been made for 14-EX, we suggest that they should be left in abeyance at least until the car returns and we get R's comments on the straight teeth. We are proposing to put the motor you are now building (2.B. scheme) on 9-EX, this will have helical teeth, we shall then get a comparison of the two types. We hope to send you particulars of how this shall be fitted in a few days. Hs{Lord Ernest Hives - Chair} RECEIVED BY/RD. | ||
