Hi guys, newbie question time. I am going to build some arrows from hazel shoots. They've been drying for over a year but I can still pick them up and bend and shape them without heat or water. Do I need to heat them to lock in the shape as I straighten them? Also, for sub 40# bows, are horn inserts in the nock necessary? If so, does the horn go from the very end of the arrow, across the notch which is then cut into it, or from the bottom of the notch so it forms the base of the nock?
Thanks
Andrew
