| Rm{William Robotham - Chief Engineer}/HH c to HPS.{Horace Percy Smith - Experimental Factory Mgr} Xc to Rm.{William Robotham - Chief Engineer} OK Nicle Rm{William Robotham - Chief Engineer}/HH Please instruct sample in each type of hardening. A third in steel in case we get into any trouble. Rm{William Robotham - Chief Engineer} 700 File TB/KNG.1/JT.20.5.41. Iron Foundry. M.40. Test Rig. With reference to your memo Rm{William Robotham - Chief Engineer}/HH.1/SW.19.5.41 re Camshafts RE.2422 and RE.2423 for the above, we would point out that we are in a position to produce these shafts in an equivalent to Monikrom which is an alloyed cast-iron with chilled tips. For your information there is also another method of hardening cam tips without using chills in the mould, and this is arrived at by a process called "flame hardening", which I should be pleased to discuss with you if you would care to call when you are passing this way. You mentioned in your memo that you had attached prints for the camshafts but would point out that we have never received these. TB/KNG. L. F.{Mr Friese} Knagg. | ||
