Tom,
Well, I say I want 2mm size only because I actually measured using calipers the diameter of the thread/string. So I am trying to get that exact size. So measuring the rigging with calipers I got 2.03mm or .080 inch diameter for the larger rigging and 1.08mm or .042 inch diameter for the smaller rigging. I measured the main large sail and got 12 1/2 inch width at the top and 14 1/2 inch width at the bottom of the sail. I apologize, but I am not familiar with what you meant regarding the diameter of the sail. Regarding the deck planks there actually are not any deck planks on the ship. It is a single piece of wood for the deck. Like I mentioned creative license was used in building this ship. It is not extremely detailed that you see in most model ship projects.
thanks
Mike Riley
