This article shows you construction process of my scratchbuilt Babylon 5 Omega destroyers phase by phase. The finished models are a bit less than 3" long. If you are planning to construct one of your own, you can use image on this page as reference and scale.
Very beginning phases. Pieces of balsa wood, stripes of cardboard & plastic circles cut out of a small tube.
More cardboad, balsa & pieces of plastic. Small plastic elements can be found from well-equipped hobby stores. Railroad modelling shop might be a good place to try. If you are in Finland, you might try this model shop.
I drew patterns on cardboard by pressing had with a pen. I drilled holes through the components in order to tie them together with a small piece of wire, unfortunately I should have used something stronger. If you are smart, you make the holes and check that they are straight before gluing anything to the hull pieces...
Assembled but unpainted model.
Completed earth alliance warships!
