I live in northern Manitoba, Canada and I have access to a lot of birch. However, most of it is new growth and has an average diameter of approximately 6". Is that too small to make use of, for bows or arrows? I've made 6 functional bows so far, but all of kiln dried wood (and some practice survival bows, but I don't count them as they have a very limited life span.). I'm living in a fly-in community now, and I have no access to dried lumber, I've been collecting some different woods to dry for winter experimenting, but not any birch yet.
Also, I just recently viewed a ocean spray sapling build-along on the forum. Has anyone tried using a birch sapling, and if so, how did you fare?
