I recommend you do some ground work before you start.
I have invited anyone who wants to come to my shop for a day, week or any other amount of time to learn selfbow building.
I get two kinds of students. The first has bought the books, amassed some tools, collected bow wood and made an attempt to make a bow on their own before they came to my shop. These guys learn the finer points of bow making and continue forward on their own making bows.
The second type of student I see hasn't bought a book, has no tools or bow wood and is completely in the dark about bow making but want to make one. These guys work hard but rely on me to direct them every step of the way and never really "catch" the bow building bug.
After we(more like I) finish their first bow they never make another bow.
I am going to stick to the first type of student in the future. My first question for future students will be "do you have any tools or a place to work"? If not, they will never catch the bow making bug and are wasting my time.
My recommendation is get together some tools, wood and reference material and jump in with an attempt at bow making. We(the guys on this site) will help you through the process.
