When paper tuning bare shafts to correct arrow flight, you need to know the direction the nock end of the shaft is pointing relative to the hole made by the point. If the nock end does not penetrate the paper in tandem with the point, the hole will be an elongated tear extending left, right, high or low in the direction of the nock’s entrance from that of the point. However, I had difficulty distinguishing which end of the tear was made by the field point and which end was made by the nock. To solve that problem, I apply lipstick to the field point. It will leave a mark on the point end of the tear, which tells me that the other end of the tear was made by the nock. I can then make adjustments accordingly. If there is no deviation between the nock’s entrance and the point’s, all is well.

Another tip: For paper tuning, get large sheets of blueprint paper from contractors who are throwing them out. Be sure to secure the paper tightly across a frame or an empty cardboard box so that the arrow cleanly penetrates the paper.
