another pair of connecting rods from the side levers 

 to the crosshead of the air pump. All connecting rods 

 are on one arm of the side levers, the other end ha\ ing 

 only a counterbalance weight beyond the fulcrum 

 bearing. The flywheel has a shaft fitted with two 

 gears, and is driven through idler gears from gears on 

 the paddle-wheel shaft; it turns at about twice the 

 speed of the paddle wheel. No other pumps or 

 fittings are shown in the engine hull, although manual 

 pumps were probably fitted to lill and empty the 

 boilers. Piping is not shown. 



The four rudders, toggled in pairs, are shown in 

 both the lines and inboard drawings, but the shape is 

 different in the two plans. Operation must have 

 been by a tiller under the gun-deck beams. The 

 outer end of the tiller may have been pivoted on the 

 toggle bar and the inboard end fitted, as previously 

 described, with steering cable or chain tackles. This 

 seems to be the only practical interpretation of the 

 evidence.

Reconstructing the Plans 



In the model it was necessary to reconstruct the 

 deck arrangements without enough contemporary 

 description. The outboard appearance and hull 

 form, rig, and arrangement of armament require no 

 reconstruction, for all that is of importance is shown 

 in the lines and rig drawings, or in the inboard profile. 

 The masts are shown to have been stepped over the 

 race on the gun deck. The iron stanchions are shown 

 in the lines drawing and in the construction section. 

 However, their position at the ends of the Battery are 

 apparently incorrectly shown in the original lines 

 plan. The construction section shows these stanchions 

 to have been stepped on the inside face of the inner 

 ceiling and. as the ceiling structure was carried 

 completely around the ship, the stanchions in the 

 ends must have been placed inboard, as along the 

 sides. The bowsprit was above deck and would 

 probabl) be secured in the knighthead timbers at
