Several thing can cause that to occur from what I understand. Existing stress cracks in the wood, getting a cross grain, flexing the bow too far too soon, firing the bow empty.
If any one knows more reasons please do post them.

Comments: maybe the wood wasn't dry enough. I heard that you need to dry the for a few months before you make the bow.
That is a possibility as it was spring when I cut them, trying to recall if I left them for the 8 weeks I think; split and in rough stock. Perhaps a full winter would be better. I do have one piece left unfinished in a warm spot. I just hope to get time before it is too dry.

How would bamboo do as a bow? Of course its pliable but wondering if its strong enough to make a difference when its strung.

Not real sure on that as you really are looking for hardwood so that it keeps its strength when you thin out the ends. Soft woods tend to be too springy with no snap. The "Cast" comes from the snap when the string hits the bow and the bow is returned to the neutral position.
It might work if you make the version the army used to teach where you take a heavy shaft for the mid part where you hang on to it. The put bamboo at the ends where the flexibility is required. Due to its grain It might work as it would have low memory I think when you bend it. That allows the bow to go back to the original resting position.
It would be more like the composite bow rather the a long bow.

Dude did you like ever finishing making that bow or what? I like the composite ones they have now saves all the wood shaving.

I finished 4 in total. One broke, one cracked and the two small one for the boys were good. I think it is because I quarter the tree instead of halving it. Might have had more consistent grain in a halve piece.

That's cool dude I wish my dad created a bow for me. You got any pics to share I want to see how it finally came out.
