I'll tell you what I have found to be the very best thing to do first: Using any of the good references you've been given in this thread already, get some dimensions down on paper. Draw it out and get your head around the task. NOW...go get a crummy old board (pine, poplar, any old thing) and lay out the bow and cut it out. Also, laying out and cutting out a sapling bow on some kind of junk wood is awesome practice. I'm speaking about 'starting somewhere'.
Get used to measuring, laying out centerline and handle, rasping, drawknifing, scraping, etc. Go ahead and cut string nocks...practice using the round file for cutting & shaping. Shape the tips nice as if for real.
Go ahead and round all edges (leave NO sharp edges) and shape handle. Feel it, rasp it, sand it and so on until it feels good. Now take a old leather glove, split it open and cut out a handle wrap and stitch it.
Yes, completely build a bow (except tillering)out of total, useless junk.
You have to get the feel of these wood removal processes before starting on good wood.
You'll have to pick up tillering on the next 'real' bow, but many people want to hit a home run on their first bow on a nice piece of wood. I guarantee it won't happen. You'll make a tragic mistake on some part of it.
After that crucial practice run, I'd suggest Jawge's bendy handle bow first out of a red oak 1x2. Tim Baker's is fine too.
Next move up to Ferret's board with glue on handle. Jawge, Tim, and especially The Ferret are all my heros. I'd save 4est trekker's very good tutorial for last (just so you can get started learning ordinary tillering first). Graduate up to a stave bow (and learn how to deal with warp, twist, grain, etc.). JMO. I was wrong once before hehe.
Hope this helps. Think on this some!
