I agree with Arthur P. If you want to take the time and effort to create your own bow and arrows and go completely primative it's cool. I think it will take you to a much more enlightened level of hunting awarness. Make sure that before you shoot at any game you test your bow and arrows first. A decent test would be to shoot at a new stiff hay bail. If your arrow makes a clean pass through then it should be good enough to kill without hitting bone. If it doesn't pass throught then you need to streighthen your bow. Also, you may want to put a piece of plywood behind it to make sure it can pierce a solid substance (ie. bone). Try this more than once at different distances. Also, take your bow to the pro-shop when you get it done and have them record the arrow speed to see if it is fast enough to make a kill. Those would be the bare minimum of things I would do before attempting to hunt with self made bow and arrow. However, I think it would definantly be worth the time and effort to do.
