| COPY. C.O.P.Y. Mr Day from F.H.R. Copy for Wor.{Arthur Wormald - General Works Manager} for Hy.{Tom Haldenby - Plant Engineer} from R.{Sir Henry Royce} Copy for J.{Mr Johnson W.M.} Re Bumping Test of Frame with Box Section Front Horns. X.711. Wor{Arthur Wormald - General Works Manager}/BM7/L271113. Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer}3/L271113. In regard to the above, I should like to know which stub axles broke and where ? Box front horns were abandoned. Why not use the new front springs with solid eyes? Some can be got in a few days at most. R.{Sir Henry Royce} Assuming it broke in the stub and was of the latest design, make the following improvements. 1. Increase the radius in the corner. 2. Abstain from boring out quite so large. 3. Use a light washer for ball bearing to push against thus. Can we do these anyway - very urgent. F.H.R. Sketch original only. me x168 | ||
