Tenbrook lives on the Westside Santa Cruz, He has ipe and bamboo. Most bows I make are board bows of ipe, soft maple, hard maple, ash and jatoba. I get mine from probuild and auroa hardwoods. I made a bow out of scotch broom 3/4" by 51"t2t that was 47# at 28" very dense material. Around Aptos should be some nutmeg, juniper, ash and I know I seen some bay laurel on freedom that was 5to6 inches dia.
