Building the MÁV gas tank car model

The gas tak construction. The body was turned from an aluminium tube, the diameter is 14.5mm. In order to have a flat, exact tubular structure, the tube was fixed in both ends. The template on the chuck end is conical, thus it can turn the tube.

The head of the tanks is a brass plug, its elliptical cover was formed by a file, while turning in the lathe. This contains a smaller plug fixed in the center, this holds the pipe connection assembly. In the tank bottom there is a tiny ventillation hole, in order to avoid higher pressure of the internal air, if the ambient temperature increases.

The frame of the gas tank car model. Unlike the previous models this car has no baseplate. The brass profiles are soldered together. This is considerably weaker construction than those with baseplate, but with the gas tanks it seems to be strong enough.

The frame of the gas tank car model with all accessories. The prototype had no brakes, this made the model building easier, too.

The car assembled before painting. This picture shows the unusual shape of this interesting car.

A close view of the gas tank car model. The buffers and the coupler was added just to take the photo. For the painting they were removed again.
