I have only been doing this for less than a year, but I have made a few board bows out of oak, maple, birch, and pecan. Different types include straight limb, pyramid, American (Flat limb) long bow, bend in the handle long bow, reflex/deflex, and am currently working on recurving the tips of a straight limb bow. They range in weight from 20# to 55# and in length from 58 inches to 74 inches.
With a good board, you can make almost any type of bow you want.
