| 473 6 7 8 members can be obtained separately from Morris Service. The underframe assembly becomes complete at the stage represented in Fig. 2, where there are shown, welded in place, the front apron, D, radiator-supporting cross member, dash-supporting cross member and frame-brace assembly, E, and the floor construction. The latter consists of four main assemblies, viz.: front floor panel, F, center floor assembly, G, with cylindrical propeller-shaft-tunnel assembly (with the right-hand and left-hand shackle brackets for the front end of the rear springs), the rear-seat-pan assembly and the spare-wheel-compartment-floor assembly. (The spare wheel is carried horizontally in a separate shallow locker below the trunk locker.) All these and other assemblies are placed in a jig prior to welding in position. The underframe completed, the right-hand and left-hand side panels and wheel-arch assemblies are located by jig and spot-welded (as in Fig. 3) to both the top and the bottom flanges of the channel side members of the underframe, giving these members an irregular box section. The side panels are one-piece pressing and include the cowl reinforcements, H, in front of the A post, the B and C posts or center pillar, and the D post. In Fig. 4 erection has proceeded to the attachment of the trunk-panel assembly, L, and one of the front-valance assemblies, M.{Mr Moon / Mr Moore} The trunk-panel assembly is secured to each side panel by a spot-welded lap joint subsequently filled with plumber's solder; spot-welding is continued along the rear ends of the wheel arches and to the underframe rear cross member. The valance assemblies, M (Figs. 4 and 6), including the front shock absorber mounting brackets, front fender stay and Lockheed brake-pipe brackets, are located by a spot-welded lap joint (later filled with plumber's solder) to the front of each cowl side panel, P, the spot-welding being continued along the side-member flanges. In addition, these valance assemblies are arc-welded to the underframe side member brackets. Next to be located (Fig. 5) is the dash-pan assembly, N; this is spot-welded to the front toe-board flange, of “Chassisless” Morris Sedan Automotive Industries April 8, 1939 | ||
