| 118H To HPS{Horace Percy Smith - Experimental Factory Mgr}/WB.{Mr Brazier/Mr Bell} from Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}4/MH.{M. Huckerby}24.4.39. BIJUR PIPE. We are thinking of changing from Bijur to Tecalemit chassis lubrication on our cars and want to use Tecalemit brass piping. Will you please compare the resistance to fatigue of the two samples of piping supplied by making two coils similar to those used to get oil to the front pivots of B.V., and oscillating them until one fails, or for 50 hours, whichever is the less. The angle of oscillation should be 15° with 3 turns. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
