I have made a lot of bows out of hickory boards and a few out of mahogany. some were too dry and exploded at full draw, I have scars on my head to tell the story. I quit putting board bows in my drying box, some have a bit more string follow than I would like but the worst of them still get 2 inches of penetration in a foam standing bear target at 50 yards { a 50# 6 foot hickory}. most ,if not all of my tragedies are from the wood being too dry.
Next month I am going to cut a hickory sapling and a persimmon sapling and try again. bowmaking is an addiction, I have made over 50 hickory bows and probably 15 of other kinds of wood. My first hickory bow from a tree has enough hand shock to shake my fillings loose,,,,
