DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} BY.{R.W. Bailey - Chief Engineer} E.{Mr Elliott - Chief Engineer} c. to BJ. Wor.{Arthur Wormald - General Works Manager} X. 8390 R4/M17.1.28. SPORTS PHANTOM - FRONT WING 3rd. (REAR) STAY. Yours scheme shews a tube standing out from the frame by a bolt flange. My first impression is that this rear end should be carried by the front end of the step. If this cannot be arranged then is it not necessary for this tube to be fairly stiff vertically? I think it should be a taper tube thus - [hand-drawn sketch of a tapered tube with a two-bolt flange] attached to the frame by 2 bolt flange, and apparently the bolt can be reached inside the frame to hold the head or even to tighten by box spanner. Don't use an extra bolt if it can be avoided, and I think in this case you do not demand any rigidity fore and aft. But you wish for some vertical support and a very definite lateral steady. Try every time to make every piece as simple as ever possible, to make and fit the fewest number of pieces, also self fitting if possible. R.{Sir Henry Royce} | ||
