Present at Meeting:- E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} RHC.{R. H. Coverley - Production Engineer} E/Lid{A. J. Lidsey} - 15.11.34. The following decisions were arrived at:- 'E' SECTION. Crankcase & Bearings. Proceed with three sets top half crankcase to LeC.4064/4074. Main bearings W/MT. Proceed with three sets of lower half crankcase, as firstvcar, but in magnesium. (Further designs are going forward to modify lower half to overcome loss of oil pressure when cornering etc. and to increase ground clearance). Crankshaft. Proceed with 3 lightened type to LeC.4032. Spring Drive. Proceed with 3 sets like the first car. Connecting Rods. Proceed with 3 sets of strap type to LeC.3860 Pistons. Order one set of Aerolite and one set of semi split - LeC.3737. Cylinder. Proceed with two sets of cylinder heads as first car (Design alterations are in hand and consideration is to be given to increasing the water flow at rear of blocks, and deleting the stud bosses which partly block up the water rails). Lightened Cylinder Liners. Proceed with 3 sets in C.I. (The cost of the lightened steel liners is to be compared, on a production basis, with the cost of C.I. liners). The rocker mechanism is to be re-considered at a later meeting. Proceed with 2 sets rocker covers like first car but in magnesium. | ||
