The recipe presented in the last post is of a small size. Many recipes require much more calculation than soap does (though recall that the definitions for the other recipes that go into it also required their own calculations.)
In this post I'll included screenshots of all of the calculations for the "hull, faering" recipe. I believe this is the largest recipe so far, both in terms of calculation and in number of sub-components.
A faering is a type of rowboat. Since this recipe only calculates the hull, the boat is not complete: there are no seats, no oarlocks, and no oars. Still, there's quite a lot to see, and I'm restricting myself to only those items which are directly being used in the faering hull. I'll show rivets, for example, which are made of copper, but I won't then go and show the copper recipe.
OK. Here is the faering hull itself.
You can see that the faering is composed of many shaped wooden pieces, some of them steamed, and that it is held together with lots of caulk and rivets.
The quantities of these components are calculated in the lengthy sequence starting at the top of the screenshot. It should be pretty readable. I would go into it here but I've been chipping away at this post for a week or two and I just want to get it out there.
Having seen what pieces the hull is made of, and how many of each piece we need, we can look at how each of those pieces are defined. First come the recipes for rivets and caulk, which are used to join the wooden pieces together.
Second and last, we have the wooden pieces themselves. You can see how some of them are immediately used as components in "steamed" versions, which (as seen above) are the ones which actually show up in the hull recipe proper. These steamed variants represent the woodworking technique of clamping a piece in place and then steaming it so that it will hold the shape it currently holds. This is used to achieve the curved sides of the strakes which make up the bulk of the hull.
One minor note: "semiGoods" is the name of the list of trade goods which are not considered finished products. Thus, although their prices get evaluated, they are not ordinarily displayed for sale on the trade table.
