X.7500 X.5500. In a previous memo. we have suggested to you that we might find a cheaper way of making the chassis floorboards than by framing. We have one suggestion we would like you to make a preliminary trial of on any experimental car. It is the use of a simple board approx. .750 thick of metal faced wood, such as 'Plymax'. We might try both single and double aluminium covered birchwood. The weight will be about the same as teakwoodboard. For single faced boards the edges are cut thus: cut-out and the metal bent over aluminium. For double faced boards one can either screw on an angle or preferably cut thus : and bend in thus: We suggest that single covered board would be sufficient. The ends will still be left long for the coachbuilder to cut to suit the body contour. The pedal gap plates and possibly heel, could be dispensed with. We would be glad if you would make up a set of boards on these lines for a car you are using. 'Plymax' is made by Venestra Ltd. DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} | ||
