BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} X7310 DA{Bernard Day - Chassis Design}1/M4.10.30. C. to SG{Arthur F. Sidgreaves - MD} C. to HS.{Lord Ernest Hives - Chair} GEARBOXES - EPICYCLIC 3rd. SPEED. X.7310. X.5310. X.523. Herewith we send N. sch. 3149. shewing the epicyclic 3rd. speed train in the revised gearbox, the object being for you to make a specimen train for the purposes of testing as soon as possible. We have also shewn an outline of the box so that you can construct one for testing purposes, but the latter is liable to be modified as we develope the controls. It will be noticed that we have provided for grinding the annulus, and the first train should be so treated if possible. DA.{Bernard Day - Chassis Design} | ||
