@ John; I feel your pain :( The two Menards stores in my area are a real crap shoot as far as finding good boards. I've only made 3 bows so far and was lucky to find 2 good hickory boards and one good enough red oak board for my last one. Had to buy a wider red oak board and cut it at an angle to follow the grain, but it did make for a decent bow. Probably is good advice to start with a simple board bow just to get your feet wet, esp. the tillering. If you have your heart set on a bamboo backed one, though, I'd say go for it (but go very slow) and check out Echatham's build along. I'm following it for the one I'm working on now, walnut with a boo back. And I'm already worried about that combination. Probably should have gone hickory/boo, but I really wanted walnut. We'll see what happens and good luck on your bow.
