Just a quick question. I am planning on getting in to building my own arrows/refletching old owns this winter. I know you can buy shafts with nocks already in them. Can youuse the same (carbon) shafts for my compound and crossbow? I know they would have to be cut done to 20". If so, how do you get the nocks out and where can you buy nocks for crossbows? Any info will definitly be helpfull. Thanks in advance.
