Tutorial PART V

A Detailed Subsection and How It’s Constructed

*The Chopper came in real handy in creating this section of my model.
The first photo shows the piece we are going to deconstruct (break down into pieces).
Here is an exploded view rendering with all of the parts roughly in place.
Everything here except for the tank wheels is made from styrene stip, rod and sheet. It’s about 3 inches long, so won’t need much material. When together it looks simple, but as you can see, it’s made up of a few pieces. Below is an illustration of all the pieces laid out.
Here is a view of the main sub-assemblies of the piece.
Here is the first sub-assembly. I took 13 pieces of styrene rod, carefully measured and cut, and glued them together on the back rectangle right up against each other. A square or other right angle tool helps keep them parallel with the base edges.
And here’s all the tubes in their place.
Next, we need to build a box around the tubes so it looks like the tubes are down in a subsurface. Here are the box  parts.
Here is the box assembled with the sub-assembly.

Next, we add a little detail to help step-it-up to the front detail piece, sort of helping to blend the front sub-assembly and back one together.
Next is the wedge piece on the front assembly.
And the extra detail that goes on the sides of the wedge. Note the sanded round corners.
Last, we add the tank wheels (see first photo of this Tutorial PART V.
Here is the final version of the above construction combined with engine detail for my 40 inch exploration vessel.
The above photo whole engine core, was then fitted into an larger engine hull assembly shown below.
End of Tutorial PART V
The photo below shows the use of styrene tubes. You bend the tubes by holding them over a candle (not to close) until they bend/fall easily. Then quickly lay them on a grid, such as a cutting mat, to form them into a right angle – or other angle desired.
