Ask anyone that participated in the red oak board bow trade.Haha. Made 3 before I sent the 4th out .1 broke , 2 not up to snuff to give away. WoodbenderDW has been coming over to work on his , I think he's caught up to me now with # of red oak and is getting sick of it. Iconicmuffin has had his share of tribulations as well. It will make a bow , but is not by anymeans foolproof. Post the pics of the pieces and we can come up with all kinds of reasons it didn't work . Then you can pick the one that helps you sleep better at night.
I'm going to say that some pieces of wood just don't want to be bows! They would rather be handrails ,or broom handles , or hockey sticks ,or......................................................................firewood. Get the marshmallows out, and grab another stick to wittle on while you're waiting on the coals. Hickory might serve you better if you can get it.
