CONVENTIONAL 8 - FRONT ENGINE SUPPORT FEET. Please receive herewith :- E.CD.1430 Strengthened Front Engine Support Feet - B.80 and C.I. Conv'l 8. This design is further to our note Da.{Bernard Day - Chassis Design}1/G.12.6.39. in which we suggested increasing the material thickness of engine support plate to FD.{Frank Dodd - Bodies}268 from .144" to .160". We have now considerably reinforced the feet at the point of fracture by bending supporting metal over and welding to the outer edges of the feet, this method of construction being preferred as it does not involve the necessity of costly dies for deep drawing of material. The original thickness of material viz. .144 should also be used so that no alterations to the wheelcase will be required. We have shown an increased clearance between engine support member and dynamo support bracket, as these two parts are actually in contact according to the present details. The tightening of the nuts on the engine feet should present no difficulty, as we understand the rubber blocks are bolted to the engine support member prior to assembly in chassis frame. Will you please detail and instruct experimentally. DA.{Bernard Day - Chassis Design} | ||
