How to Make a Lighted Nock With FOB

When shooting in low-light conditions it can be easy to mislay arrows that go wide of the target or pass right through it. This is where lighted nocks come in; they are triggered when the bow is shot and signal the position of the arrow with a bright LED light. The FOB system arrow flights can fit very neatly over a lighted nock. FOB, though it looks like an acronym, does not actually stand for anything but comes from an episode in the inventor's past. FOB flights are a specially designed plastic aerofoil that takes the place of conventional arrow flights or fletching.

Instructions

    • 1

      Cut the base of an old nock using a hacksaw, leaving about 3/4 of an inch. Sand around the inside of it until it is just narrow enough to push down inside the shaft of the arrow and wedge tightly.

    • 2

      Mix a pea-sized amount of the epoxy resin. Spread around the base of the bob light. Push the base of the light down into the cut-off section of knock. Hold it there tight and allow it dry. Push the cut-off section and light down into the shaft of the arrow.

    • 3

      Leave the tip of the light protruding; 3/4-inch of the light is sufficient. Fit the FOB flight over the light and press it down against the end of the arrow shaft.

    • 4

      Drill a small hole through the fluorescent nock between the two sections that fit around the arrow. Position the hole in the center of the nock and fit the nock over the bob light. This hole allows the light to pass through more clearly. Do not glue it in place; when the arrow passes through the target it will nock the FOB off the back of the arrow. If the nock is glues in place behind it it will be damaged rather than popping off with the FOB.
