The Collins class submarine has been one of those boats that has interested me for many years. I have made a number of attempts at modelling the Collins subs in a couple of different scales but I have never been happy with the results.
Recently, after updating my drawing of the Collins submarine, I again started constructing a new plugs to take fibreglass moulds from for a 1:72nd scale model. The photos below show my progress.
The main hull for the plug is made from PVC sewer pipe.

A few small parts were also moulded in polyurethane.
