I think it was Pearl Drums that helped that guy build a board bow a little while back. He walked him step by step thru the entire process and it took probly 15-20 pages. I don't have the link but if someone else does then that is a great thread for just starting out. It will help you to realize how much you have to slow down and take it step by step.
Keep your eye out for a tree to harvest and split even if you do the board bow because staves still take a long time to season and if you wait then you will be in the same position as you are now....wanting to build another bow and don't have any seasoned staves. You got to think in the present and for the future.
