Conversion of a WWII “Big Gun” Cruiser to a Guided Missile Cruiser - Now Completed

The model in the background is the completed conversion of USS Boston as detailed in the post of November 26, 2006. The model in the foreground is of USS Los Angeles, the ship kit from which the USS Boston was built. These are both Baltimore class heavy cruisers.
This drawing of USS Boston was copied from a magazine, modified according to photographs and resized to 1:700 scale in order to provide a plan from which to make the modifications to build the model.
This is another view of the two ships from the reverse angle. This will allow comparisons between the two ships. You will notice that the shape and width of the stern is very different.

The construction of the tower mast structure amidships used an interesting technique. Double sided tape was laid down on a surface. The modeller drew the plan for one side of the tower on the tape. He laid plastic rod down on the drawing on the tape, cutting each piece to length on the tape. He then applied a small amount of liquid plastic glue to each joint. When the glue set the piece could be removed. This was done for the front and back of the tower. The following assembly task was relatively easy.

Beginning Nonsuch

Shown here is a model of Nonsuch in the very early stages of construction. Nonsuch was the ship with which Radisson and Des Groseilliers voyaged to Canada and founded the Hudson Bay Company in 1668. This model is being built in 1:96 scale (1/8 inch to the foot). The coin in the picture is a quarter.
The two halves can be seen here held together with clips. Once the research has been done and adequate drawings either having been obtained or drawn the first stage of building the model in this case was to carve a plug using the inside dimensions of the hull.This plug is then cut into five sections as can be seen here. There are two outside parts and three inside parts. Once the hull has been constructed, the center part of the plug can be removed. This allows the other two inner pieces to collapse inward and be removed after which the two outside pieces can be removed.
The various sub assemblies are held together with pins. This allows removal and adjustment until the parts must be finally glued or otherwise fastened together.
As can be seen here grooves have been cut where the deck shelving timber and other key longitudinal beams will go. As well there are lines drawn on the plug to indicate the location of key frames.
The model will be planked on the top portion only, leaving the inner detail below open for viewing. The builder chose to build this model exclusively from holly and ebony in an attempt to simulate the look of prisoner of war bone ship models of the Napoleonic era.
