Thanks guys I do have 2 rasps One is a small 4 way and the other is a large feriers rasp.
I started on one billet yesterday and once I got the bark off I found a deep crack down the back and a deep worm hole. I was able to get through both and have enough left for the bow. I think following growth rings is fun I like how you can feel when you hit the light colored part and then it gets smooth again when you are through. I had been intimidated by osage because you need to follow a ring. Now that Ive tried it I love it. Much more fun than making a backed bow so far.I like that no 2 will ever be the exact same. Jesse
