| X3Y45. To EH. from R. {Sir Henry Royce} Copy to CJ. " " BN. {W.O. Bentley / Mr Barrington} " " EH. RE REAR SPRINGS. . R7/G17.11.19. ---------- X.2628. X.3745. ---------- I feel certain that you are mistaken with reference to the squeaking being due to the use of the thick plates. Actually the pressure between the plates is less with the thick plates than the thin ones. In every case in my own investigations, no matter how dry the leaves are, they never squeak, the noise comes from pivots, and from such motion where the piece winds up slightly before it moves. There may be possibly something due to the fact that we are splitting the rear half of the long leaf of the spring, which may cause it to squeak when moving sideways. I quite agree with the trial of the leather gaiters, but I think these will not look very nice when they have been in use for, say, a year or two. However, it is well worth fitting some. A model was sent to me sometime ago by Mr. Bailey, but I did not think the scheme was very practical. However, I think thy are worth a trial.
