Check out PaleoPlanet.com our you can google it bud its got lots of awesome selfmade bows and people who are into doing it old way.
I love looking through there and seeing how awesome they are some of these self made bows are just pieces of art man.

Not all wood is created equal for purposes of archery, you can definatly make a primative bow to kill deer it depends on what you use and how you use it. This forum is awesome place but if you looking for help in the primative world you go to go to where the primative practitioners are. Id like to see your bow post some pics of it!
