Frode. I have a neighbor that owns a small saw mill. He is all the time cutting diferent types of wood. What is nice is, that he can cut them like 2"x 2" 72" long. I live in Illinois, so i know he cuts oaks, hickory, walnut, hedge(osage), cherry, maples, hackberry, locust, you name it, and if its Illinois, he may have a tree trunk laying around to cut. I told him one time that he should start cutting left overs for riser blocks, limb laminations, and board bows. I think he can cut hickory backings also. I don't know how thin he can make them. He said he would if the demand was there. I don't have any idea what he would charge for something like that, but could maybe find out.
