Meccano: model 10.3: Cargo-boat. Personnal addons (3/6)

Superstructures

For the base of the funnel, I replaced the hinged plate (198) by two flexible gusset plate (201) linked by a strip of 6 holes (4). The braced girder of 11 holes (100) on each side are doubled.

The edge at the back is formed by two flexible plates of 5x9 holes (191). Those two plates are joined at the bottom by a strip of 5 holes (5) as shown by detail B. The bolts B are bolts of 12mm (111a) that hold a coupling (63) against the plates 191; the bolt A is a bolt of 12mm (111a), and allows to maintain the coupling 63 against the horizontal flexible plates formed by a flexible plate of 5x5 holes (190) and two flexible plates of 11x5 holes (192). Finally, a rectangle of angle girders strengtens the structure to avoid it collapses because of the weight of the funnel; this rectangle is made of an angle girder of 15 holes (8b) held between the coupling 63 and the plate 190 bis the bolt A, of two angle girders of 5 holes (9d) on the sides, and two angle girders of 11 holes (9) which overlap on 5 holes for the base. Those latter angle girders are fixed on each side to two angle girders of 37 holes (7a; those angle girders are part of the corridor along the hull, whose structure is explained farther).

Finally, each end of the flat girder of 15 holes (103k) are held against to an angle girder of 4 holes (9e) by a flat girder of 2 holes (103l). The angle girders 9e are fixed to angle girders of 25 holes (8) by bolts that are not fully screwed. Otherwise, the lower angle grider 8 is not well arranged on the model: it should be turned towards the bottom, not towards the top. The H point is the fixation point for the superstructure of the corridor.

The structure next to the life-boats is modified as shown on the two opposite figures. A special strip of 5 holes (6), a flat girder of 4 holes (103g) and a strip of 5 holes (5) are fixed to the upper angle grider (9 and 8b). A flat girder of 2 holes (103l) fixed on the strip 5 allows to hold two double angle strips of 11 holes (48d); the bolts are not fully screwed. At last, a flat girder of 5 holes (103f) is horizontally fixed to the strips located along the life-boat.
