1/72 Akitsushima (秋津洲) IJN Seaplane Tender Scratchbuild Part IV

The superstructure was built up in a series of lifts. The pieces making up the bulkheads were beveled to make a sharp edge, and the seams were reinforced with superglue from the inside.  This resulted in a strong joint.
One of the challenges of a lengthy build is keeping the mojo up when finishing the project is still months away. I thought of  each subassembly as a separate model.  It’s easier to focus on components, and each completed section is a small victory along the way.  This is the forward superstructure, the upper sections are not glued down as there are many details remaining to be added.
The vertical structure of the crane was broken down into a stack of tapering cylinders. Disks determined the upper and lower diameters of each section.  The base of the bottom section is a pill bottle.
Plastic sheet was wrapped around and cut off level with the disks to form the exterior. The seam is an obvious problem and caused more trouble than I expected.  More on this later.
Pulleys were made from 1/35 scale armor bogey wheels. Grooves for the cables were carefully cut into the faces of each one.  Fortunately, the Japanese magazine Navy Yard vol. 10 published an article on Akitsushima which included pictures of builder’s drawings which showed this detail clearly.
This is the crane assembly and after deck house. The builder’s plans and photo enlargement matched perfectly, although there were some details drawn as alternates on the plans so it always pays to compare the drawings with photographs.
This is the rough shape for the stack. The ends are a piece of PVC piping split in half, with Evergreen spacers to achieve the correct width.
The stack was wrapped in 0.010″ sheet. This gave the stack a smooth, seamless surface and allowed a lip at the upper edge.  Several exhausts were routed through the stack.  The center four are for the Kampon diesel engines, the remaining are likely for electric generators and galley exhaust.
The major subassemblies posed on the hull. Test fitting is always important in any modeling.  If you look closely you can see some additional details have been added to the main deck.  Always good to see a project start to come together.
A view of the port side. The platforms for the 25mm guns are fabricated and test fit in position.  The main guns and ship’s boats are 3D parts printed by Shapeways.  Everything is still loose at this point but it helps to visualize the progress and to check general appearance and dimensions.
