Hi all. This is a bit of a shot in the dark, but does anyone know what types of wood might be used to make the rafters of a roof on a 1970's house near london? I'm currently in the middle of having a loft conversion done to my house, and have rescued 3 nice long rafters that look in good condition and are pretty straight grained. I have a few projects that I can use them for, but the first thing that entered my mind was could I get a few free (or ?30,000 depending on how you look at it) board bows from them that I can experiment with? I'll probably do some bend tests before I go ahead and try making a full bow out of one, but was just wondering if anyone had an idea of what wood it might be?
