| 300b Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.1/MA.12.8.36. CONTINENTAL SPORTS PHANTOM III EXPERIMENTAL CHASSIS. On the electrical system for this car we could save weight as follows :- (a) Battery and Battery box. A 25/30 HP. Thin plate battery could be used with a standard 25/30 type battery box. This would save 17½ lbs. on the battery and 4 lbs. on the box, giving a total of 21½ lbs. (b) Dynamo. A standard 25/30 HP. dynamo could be used if the gear ratio was raised to 1.5 - 1.0. This would effect a saving in weight of 6 lbs. Added to this of course would be the slight extra weight of a packing on the crankcase to accommodate the smaller diameter and the use of a larger pinion for the drive to the dynamo. There would be an appreciable save in cost by both modifications and we are ascertaining what this would be exactly. Hs{Lord Ernest Hives - Chair}/Wst. | ||
