I have thought about it. How are you going to practice enough with the points? I guess if it is a home made job, the shot would have to be very close.. It seems that probability for wounding a critter would be pretty high..
I thought about making the points out of iron like a damacus blade...
I ahve a ways to go yet, I am still workign on getting a deer and bear with my recurve. after that, I might go for the home made bow& arrows.
good luck, make sure and post you results if you try it.
