I sure do like to make bows. What kind of wood do you have access to? Tools? How about bowstring ma terials?
Use a hardwood like elm, oak, ash, hickory, maple, most any hardwood will work. For a first bow, buy a five dollar 1by2by6 (actually 1 1/2" by 5/8" by six foot) foot piece of red oak. Make sure the grain lines on all sides of the board are striaght and there are no knots. You can work down a bow with a hatchet, or a chisel, if you dont care about finished appearance. If the store has maple available, use that also.
Bow Layout
Take the six foot redoak board stave, and find the middle. Measure 2 inches on either side. This is your handle. If you have a big enough hand, leave the handle full width. If you have difficulty doing so, you may narrow it an eight of an inch, but not any more than that. These are directions for a 45 pound bow, at 28" of draw. A regular old pocketknife will work.
Make the tips of the bow 1/2" wide. Dont cut in nocks just yet.
Now comes the difficult part. Tillering is basically making wood bend by making it thinner. For a good, efficient bow, you will want to make the entire bow bend equally at full draw. Like this pic, of an elm bow I made.
Therefore, you want to remove a lot more wood near the midlimb of the bow, than you would near the handle. So procede on doing exactly that. If you want something to work on, make the handle full thickness, and the tips about 1/2" thick, and draw a straight line taper between those two points. Take a jackplane (if you have one), and leave the handle alone, plane a little on the immediate wood by the handle, more wood further out, and test the bend of the bow by setting it up, and pushing the limb, so the tip rests on the ground. If it is correct, with no "hinges" or areas that bend too much, or stiff spot, areas that dont bend enough. Make sure you leave the tips stiff, and the wood right by the handle stiff or barely bending. This is to reduce set, which is the tendency for wood to remain in a bent position after unstringing.
The tiller on that elm bow is good tiller, it hasn't taken much set, even though it is not much more than an inch wide, and 45 pounds. It is plenty enough weight to kill a deer with, and I think that at 10 grains of arrow weight per pound it may shoot something like 147 fps, based on shooting tests.
I have to get going, I'll finish this later today.
While you are waiting, here are some excellent sites to look for. When dealing with topics like archery, it is better to learn as much as you can, and just go out and make a bow, learn from your screw-ups, and dont ever lose your determination. So while you all wait to know how I make bows, here are some othere peoples sites where I learned from.

http://www.primitiveways.com/sapling_bow.htmlYou should dig in the archives on this one, jam packed full of info. Took me about four hours to read a lot of it.
