Also if you have a hatchet, machete, cleaver, drawknife or something else for faster wood removal that will help.
I should also mention that you can make any bow with these tools not just board bows, i just think that is the best place to start for a beginner that will probably want to get started right away and have minimal investment. If you have access to bow wood, osage, hickory, elm, etc, etc. then cut a tree split staves and while your waiting for them to season go get a hickory board to start on.
