The gratings are finished

The gratings are finished. At the suggestion of Stephan and Herby63 I made the cambers a bit more subtle, and I do indeed find that nicer myself. They are now also much lower, which seems more correct to me: they run from 1 to 2 mm, which would be 6 to 12 cm in reality. Now just a coat of clear matt varnish and then they can go on.

Why the camber?

Hans Groenenberg thought the gratings looked crisp, but the camber puzzled him a little. I understand that, because you rarely see it. I referred earlier to the book The Arming and Fitting of English Ships of War by Brian Lavery. He states that the gratings have a curve towards the centreline of the ship. I have done some more digging and come across it again on some older models, such as HMS Bellona of 1760. What I read about it is that the camber was given for strength, and I find that a good explanation: standing on something curved is always sturdier than standing on something flat. But then again, perhaps it is an urban myth. The main thing is that I like the camber, so that is enough really. Still, it would be interesting if anyone knows exactly how it works.
