| To By.{R.W. Bailey - Chief Engineer} c. to RHC.{R. H. Coverley - Production Engineer} +342 Hs{Lord Ernest Hives - Chair}/Les.9/KW.22.10.35. Rear Autolock Damper, N.Sch.4525. Will you please delete the 1.800" and 1.850" dia. counter-bores each end of the cylinder bore of the casings F.87763/4. We understand that this counter-bore has no advantage for facilitating machining, and it is liable to cause air locks in the damper. It also causes an undesirable reduction of metal thickness between the cylinder bore and the bush for the locking sleeve. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A. Leslie} | ||
