AZN, I'm really needing to finish these bows in couple months, so waiting is not an options
Justin, thanks for the advice. And thanks to rest of you for your suggestions.
Since there is some concerns about condition and origin of the boards, I'll go ahead and give the history for them at risk of being tarred and feathered.
I cut the tree a couple months ago and cut the boards out from one of the staves. Self bowyers--I did keep the other staves for self bows. As a matter of fact the first I'd planned to make a board out of, was just too pretty not to be a self bow. It begged me to make a self bow from it. It's roughed out and drying right now.
So, these boards are not kiln dried if that make a differ as to whether it is adviceable to recurve or flip the tips.
