| Try & see N.K. for brief X8450 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer} C BY/HEB{H. Biraben} BY10/H.{Arthur M. Hanbury - Head Complaints} 21.2.27. RECEIVED SIDE STEERING TUBE - N.Scheme 2258. Referring to BY6/H.{Arthur M. Hanbury - Head Complaints} 4.2.27. on the above subject, I would like to know whether you are in a position to release this design for changeover work. We find that the Repair Dept. had not ordered up their material for any changeovers in accordance with the instructions we have issued for C.2. and D.2 Series. It is of great importance that we make a move in the near future and unless N.Scheme 2258 in the Experimental trial can be agreed to, it means that we must order parts in accordance with C.2. and D.2. to deal with a certain number of changeovers. On C.2. and D.2. Series the scheme instructed allows .2 movement each side of the ball, that is, a .4 total at each end, but N.Scheme 2258 as issued gives .250 each side and each end, this dimension representing the maximum that we can obtain with N.Scheme 2258 on changeovers. If N.Scheme 2258 as it was originally instructed, with .3 movement each end, is instructed for E.2, it would mean a new set of tools, but if we can start off on change-overs with N.Sch.2258 modified to give .250 movement, the number of parts will justify the tools for changeovers, and then I think there would be no difficulty with Wor.{Arthur Wormald - General Works Manager} in starting off with .300 movement for E.2. Series if and when it is instructed. OK 25/2/27 BY.{R.W. Bailey - Chief Engineer} BY | ||
