Nock-to-Bowstring Tension

The nock tension ("snap fit") necessary to separate the nock from the bowstring serving can be very critical, especially on light draw-weight bows (30 lbs. and under). Nock tension should be tight enough so the arrow can easily support its own weight when the arrow is hanging vertically on the bowstring (nock against the nocking point). To check this, hang your arrow vertically from the bowstring, and give the string a sharp tap with your finger on the serving about 1-2" (2.5-5 cm) from the arrow nock. The arrow should separate from the string. If it does not, the nock is probably too tight for most target archery. For hunting, a tighter nock-to-bowstring fit is often preferred. To accommodate this, Easton designs nocks in several string groove widths. Easton's Super Nock is designed with the tight press fit bowhunters need to keep an arrow on the string in all types of hunting conditions. The 3-D Super Nocks feature a snap fit with slightly less string tension, and a nockset d�tente for shorter bows. The "G" nock is available in two string groove  widths. Now that you have completed the preliminary adjustments, you can start the tuning process. Four methods of bow tuning are described on pages 5 through 14:   the Bare Shaft Planing Test, the Paper Tuning Arrow Test, Short Distance Tuning, and Broadhead Tuning.
