How tight should serving material be applied?
Tight enough to hold the serving in place and stop it separating. Thats not very specific but what it means is that if you serve too tightly, there may be problems. In the center, you are crushing the bowstring material which can cause problems at a point where flexing occurs, and at the ends, if the serving is too tight, it cracks open when bent around the cam, especially if the bow is fitted with a radical cam. So experiment with serving materials which offer some adhesive coating for the ends such as our black No. 2D.
