Bailey - Chief Engineer} c. to HPS.{Horace Percy Smith - Experimental Factory Mgr} Rm{William Robotham - Chief Engineer}/FWK.26/JH.13.1.39. WRAITH BUMPER CHASSIS. The welded steel pan which you recently supplied to us has cracked round the front bearing of the lower triangle lever on the near side after 4 1/2 hrs. bumping on 3" cams on the above chassis. Since the bump is being run chiefly for the purpose of testing this pan, we have ceased running. Will you please advise us whether you wish us to test another similar pan, or whether the above results are all you require. Rm{William Robotham - Chief Engineer}/FWK. | ||
