[Handwritten Text]: To: Mr Barrington Re: Weight Reduction "G" Depart [Top right corner]: X200 18-6-1911 X. Hill Chassis weight [Main Body]: There does not appear to be any one piece that one could say is much too heavy. There are parts which by calculation could bear reduction ie the Rear axle Tubes & Torque Tubes. these however are already very thin when considered in relation to their diameter & if they are further reduced there is a real danger of a coarse finish materially affecting their strength. I am certainly not in favour of reducing the Torque Tube altho my latest tests shew they are generous in their proportion for the reasons above mentioned; they are only too strong where they are large in diameter & the section of metal is relatively thin. | ||
