The following are notes which we made after a visit of a representative from the P.S.C. to discuss the design of the Myth Monocoque body. (1) The square panel corners of the type used on the rear quarter and boot of 12.B.V. would entail a large number of extra welds and turned over flanges approx: 3/8" from the sharp edge. These would be spot welds, hammered, and then loaded with solder. P.S.C. said that it could be done but would expect very considerable difficulty in obtaining the quality of result with quantity production and the labour employed. The type of corner used on Myth Ripple would be a much easier proposition as it would entail no extra welded joints. The extra coining die would be the only added expense. (2) The P.S.C. said that they did the pillarless saloon for the Fiat and expressed no alarm at the suggestion of our possibly requiring such as body. They would put the upper hinge of the front door in the moulding and would use the normal silent travel locks with adjustable sockets in the cantrail and base pressing to facilitate the hanging of the doors. (3) We can have front wings with an angular joint between the wing and the inner valance as on 11.B.V. This would entail an electrically spot welded joint at the join. Rm{William Robotham - Chief Engineer}/EAG. feared this would cause rusting to occur. (4) The cat walk being so high caused it to be suggested that the bonnet side plate should be made a fixture, welded into position. There appears to be no real reason for opposing this suggestion as in any case the exhaust valve tappet adjustment will have to be made through windows underneath the front wing. (5) It was stated that light section front pillars such as we are hoping to obtain (and similar to those on B.V.) are being provided on future quantity produced bodies by P.S.C; and also that the amount of stiffness contributed to the body base structure by the shell | ||
