The cowl underneath the vehicle was cut from balsa and covered in automotive filler. A very important lesson, which I learnt from reading David Merriman's excellent article on the 'Dove', was to put tape over the model and then use automotive filler to get the correct contour of the part you're fitting. Thanks David that was invaluable! This way, I was able to build and paint the part separately, without having to blend in gaps and end up re-spraying the model! This cowl was fitted with a grill and glued underneath the cabin.

The wheel halves were then glued together and fitted to the brass axel. The track was cut to the correct length and glued back together over the wheels. Plastic tube was fitted over the axels to prevent them from moving from side to side
