If you want to use bamboo, you'll probably need to order it from an island further north. They have a lot of Moso and Tonkin bamboo, both of which are excellent for both bow making and arrow making ad were used traditionally by the Japanese. Bamboo is tricky though since there are so many species, many of which are total crap. With bamboo, it is important it is grown at elevation and given plenty of cold. The stuff you'll find at sea level tends to be a serious hassle to cure (even when cut in winter) and makes weak bows that take a lot of set. If you can locate a bamboo dealer (should be easy there) you'll have a cheep supply of bow material. Just laminate two pieces together inside to inside with the ridges facing outward on both sides. You should laminate with Tight Bond 3. I'll send you some if you can't locate some there. Just be sure both sides of the lamination are completely smooth with no gaps. Roast the belly lamination good and well before laminating together with a heat gun for around 45 mins or more till it gradually darkens. Some guys go all the way to black for the belly lamination. Either way, just take your time roasting it and do it slowly and evenly. I really prefer the feel of a wood bow, but a boo bow made this way is still something really nice to shoot and is hard as hell to break. Could be a good option for you.
