i’ve made bows from plum, red oak, white oak, osage, hickory, ironwood (hop hornbeam), ash, elm, maple.
there are soooooo many woods that canbe used for selfbows, the most important thing to rememeber is that each wood will dictate a different design. you can’t make a red oak bow to the same dimension as an osage bow or you will be dissappointed, (i think that is why woods like red oak have gotten a bad wrap). but if you make a longer or wider bow, you will end up with a very high performing selfbow of a “lesser” wood. As far as i am concerned there is no such thing as a “lesser” bow wood only poor design choices for the wood at hand.
