Hey Wayne, White oak is a good wood and it will stand up to the stress fine. You may however want to shorten the bow to atleast 60, I would personally do 58 if you are going to sinew back it. You can shorten it, steam the ends bend it and let it dry. while its drying seperate the sinew and you should be ready to go. You will find that sinew does wonders to the wood and Im sure you will love it. Anywho good luck with it and dont be afraid to try anything new.
