I love making boo backed osage or yew
Jsmoffitt03,for the style of relexed bow I make with a boo back,tapered center lam(.120) and core(3/8") its never thicker than 3/8" - 1/2" at the handle.
I taper everything,the boo,lams and core before glue up.My bows are reflexed 3" and settle to 1"reflex after break in,62" ntn and 50-60lbs
