Having spent a bit of time last night researching the various measurements for different componants I had a go at the roof and cutting the windows this morning. This video on youtube has been of great help:

Although it is a computer generated video it shows the vehicle in ways that an ordinary video could not.

Last night I completed cutting the components for the outer layer of the engine housing.

This morning I cut a piece of balsa wood to side and sanded it into the shape I needed for the roof.

After this I checked my research for the shape and measurements of the windows and then cut out the windows from the sides:

I then did the same with the front and rear windows:

Before these components are glued together I intend to try and angle the windows inwards a little as they are on the prototype. I have filed them slightly so that they are kind of in that direction but it is not noticable enough at the moment. I think this is one of the most problematic issues facing this build at the moment, because of the size of the vehicle in N Gauge it is difficult to make these very minor adjustments without breaking the bits of plasticard. I am hoping that when I add the glazing I might be able to work out a way of encouraging the sides to slope inwards gently.

As well as cutting the windows I cut a hole in the front of the cabin in tront of where the engine housing is going to be placed. The chassis that I purchased is going to be repositioned so that the top of the engineblock is just in front of this hole. On top of the engine block of this chassis is a small directional lighting LED which will (I hope) shine through this hole and then through the two holes I will be drilling into the front section of the engine housing to give me lighting for the vehicle.

I need to smooth the cut edges down a little and start the preparation painting of various components. However until the chassis arrives I can only make some minor preparation work on the vehicle.

I think this project (so far) has been the most enjoyable thing I have done in terms of modelling.
