Bailey - Chief Engineer} (Handwritten: By is crossed out) EV {Ivan Evernden - coachwork} 5/IH.15.11.33. (Handwritten: #S) SIDE WHEEL CARRIER, VULTURE(Experimental 6 CYL OHV LONG STROKE / Aero Engine), etc. ------------------------- The centre of the side spare wheel on Vulture(Experimental 6 CYL OHV LONG STROKE / Aero Engine) appears to want to be about two inches in front of the back of the dashboard. In this position using J.3. wheel carrier the forward foot of the carrier bracket lands immediately opposite the rear engine foot fixing and it looks as though the bolts of the two may have to be co-ordinated. If you have a scheme for the fixing of the engine foot support on the frame, we would be glad to have it, when we would set out the side wheel carrier. In this connection we would be glad also if Hs {Lord Ernest Hives - Chair} would tell us whether he considers the inch and a quarter tubes sufficiently rigid on J.3. (Handwritten: YES) We are inclined to think they should be one inch and a half in diameter. The frame is adequately steadied by the dashboard and we believe that we are right in saying that when J.3. came to West Wittering(Henry Royce's home town), we were shown that the flexibility that remained in the side carrier was to be found largely in the tubes. The rear step bracket of the J.3. frame now comes opposite the sheet cross member and we have indicated on our scheme a four-bolter step iron which straddles this cross member's fixings. To fall in with the balance of proportion of the body we are placing the top face of the step brackets eight inches below the level top of the frame. Ev. {Ivan Evernden - coachwork} Since writing above it appears that the side steering tube will foul the side wheel carrier on the left hand lock. The carrier is approximately 1.250 ins nearer the steering box than on J.3 and on that car we had trouble with fouling. | ||
