Tomm why dont you make some Hupa or Modoc designed bows from it. They would remove the sapwood and design the bow and then sinew back them so small knots are no problem because of the sinew and you end up with a very nice hunting weight bow great for brush or densly wooded country. Very light in the hand too with a great cast within hunting ranges. Start with the modoc design since it is easier to make, from everything I have heard, then advance to the Hupa style. You should be able to get quite a few bows out of the tree this way. The bow will likly draw only 20"-24" but you will have some great bows this way!
