T e planer portion that spaces the pontoon and nacelles was constructed fi rst. T e brass rods extending from the bottom will be the connection locations for the main hydrofoil. Four pieces of rectangular brass bar form attachments between the harness and the nacelles, whereas attachment to the main pontoon would have been bolts through the top and bottom stringers as well as the second pontoon hoop. (Figure 11)

T e superstructure that forms a pylon to hold the engine was assembled on a jig. T e jig allowed me to ensure the pontoon-nacelle harness would remain perpendicular to the pylon in all necessary dimensions. Here, as well as in other portions of the model, brass parts were connected making use of a resistance soldering unit. It can be noted that sacrifi cial engine support wood beams helped hold six vertical pieces in the correct position during construction. (Figure 12)


A smaller but similar harness was built to hold the aſt hydrofoil in place. (Figure 13)


Aſt er test fi tting and fi nal adjustments, the harnesses and pylon were primed and painted in a light blue/ bluish-grey color using Vallejo Air products. T e color was chosen due to references alluding to such a tone. (Figure 14)


10. Pontoon nose cone. Connecting Pontoon and Nacelles


T e main pontoon and two nacelles are connected via what I tend to call a harness. T e harness also supports the hydroplane’s engine. Dimensions for this subassembly had been determined through careful measurement of numerous photographs. T e structure was made entirely from brass; tubing was heavily used together with a few segments of rod and bar.
