My first 15-20 all shot and shoot to my knowledge. Then like Mike, I got cocky and have broke at least 10-12 since those first good ones. Crap happens.

it took me about 6 bows to get a shooter, and have made about 20 since then with a few breakages mixed in. some of those 20 turned out real nice but i think i got lucky with them. Only recently does it seem like things have "clicked", now tillering is easier, knowing how wood reacts to my tools, etc. This has all been with straight limbed longbows, don't mix in the "extras" like recurves, sinew, etc till you really get the hang of just using your tools and making a shooter, then you can advance your skill. Just my thoughts, keep at it!

Oh and one more thing...TILLERING GIZMO!

Thanks guys.  I never give up!  I know that I have a LOT of learning to do.  Fortunately, I have a friend who is very good at bow building and I pick his brain every chance I get.  He showed me a few things on this bow I just made a few mistakes after leaving his house.  And I do need to check the grain of boards that I pick up.  I think that was my biggest mistake now that I think about it.  I will take every thing that you guys said and learn from it. 
And what is a "tillering gizmo"?  I looked it up and understand how to make it.  But do you mark along the edge of the bow? 
Thanks again

I prefer to have a piece of threaded rod m5 or so instead of a pencil.
To use you put the bow on a tillering stick, then run the gizmo along the limb and look at the gap between the gizmo and the bent limb.
Once you try it it will become obvious. They are very useful with board bows and you should never get a hinge if you are careful as they show any extra bend very clearly.

I have a tillering gizmo and have used it.  But, I seem to spend more time fiddling with the gizmo than I do tillering the bow.  I get the pencil length adjusted so it's not marking the whole limb, then the lead wears out.  I have to unscrew the pencil, resharpen and adjust the length again.  Too much work.  I use a 4" block of wood and just look at the gap, then mark spots with the pencil.

the key is not to use a sharp pencil since when i wears the length changes so fast. use a blunt pencil so it doesn't wear so fast, only swipe once or twice on the limbs then go back and mark them better if you need to. I don't think i spend more than a minute fiddling with the gizmo on any one bow.

Maybe unique in this case,but I never shot a real bow before trying to fashion one.so I never new how heavy it should feel to brace,floor tiller or pull by hand on a tillering stick.so once getting a sense for it things became easier.floor tillering in my case very important and get things fairly even before putting it on a tree.I think that there is a distinct advangtage to get a sense of the balance and weight of bow,be it modern one or not.
Some like motorboats,I like kayaks,some like guns,I like bows,but not the wheelie type.

hehe I don't even have a tiller.

i know I suck at making bows... but last night my friend bought 3 red oak boards.. we knocked out a bow in 2 hours(including dinner) with a hand plane and 2 rasps.  Stained it, and put a handle on it last night. Tommorow he's going to mayland and going to shoot with family.put about 100 arrows through it so far. around #65@26, 70" long, super thin tips...
i bought a #35@28 red oak backed with linen... and it broke.

Man I learn a lot from breaking bows.  (learned quite a lot recently) Still have a lot to learn.  If you can get a good idea of why it broke then in a way it's a success because it improves your skills and knowledge of what to do better next time.  You can't loose dude.  Just start another one and then another one.....keep bugging your friend and ask all these guys a bunch of questions.  Build alongs are huge too...
Talking trees. What do trees have to talk about, hmm... except the consistency of squirrel droppings?

My first two bows were shooters and then I broke seven in a row before I made another. I've made over a hundred bows now and I feel that I'm just starting to get the hang of it.

Like I said don't use a pencil! It doesn't make sense. A piece of threaded bar is infinatly and micro adjustable. With a gizmo you have to be able to very finely adjust it or else they are worse than useless!

it happens everyonce in a while. 

Bamboo bows will break also.  But the Boo is usually reuseable.  for me it tends to bbe either grain related or hinge related + impaitence.

Go slow and look for signs of bending issues and address them as they show up in early stages and shallwo bends.  Then get it back the full amount.

If you are laminating more than two layers that takes more planning.  I still loose a few because the core was too thick.

Maple isn't an easy wood to start with.

You Might want to try hickory backed maple hickory is a dense wood but it is flexible and very good in tension it is one of my favorite bow backing an maple is not very good for a bow from my experience the reason it probably broke is because of the wood combo
