Abstract

A special tuning point for archery arrows for use in tuning a bow, target shooting, and non-big game hunting has a weight approximately equal to a broadhead selected for use by an archer using and tuning the bow and has a balance point position ahead of the arrow shaft to which the point is secured approximately equal to that of the selected broadhead. The tuning point is secured to the forward end of an arrow shaft substantially identical to that used with the selected broadhead to form a tuning arrow. The tuning arrow is used in tuning the bow. In this manner, the bow is properly tuned for not only the tuning arrow, but also for the arrows with the selected broadhead.

Claims

1. A tuning point for archery arrows wherein the tuning point has a weight approximately equal to the weight of a given broadhead and a balance point approximately equal to the balance point of the given broadhead, but does not have blades, and wherein the given broadhead has a means for securing the broadhead to the forward end of an arrow shaft, has blades which begin and extend forwardly of the means for securing the broadhead to the forward end of the arrow shaft during flight of the broadhead, and the balance point of the given broadhead is located forwardly of the means for securing the broadhead to the forward end of an arrow shaft, comprising a body;

means for securing the point to the forward end of an arrow shaft; and

a forward tip on the forward end of the body;

the body, means for securing the point to the forward end of an arrow shaft, and the forward tip together are configured so that the tuning point is of a weight approximately equal to that of the given broadhead, and has a balance point approximately equal to that of the given broadhead.

2. A tuning point according to claim 1, wherein the weight is approximately equal if within about 21/2 grains.

3. A tuning point according to claim 1, wherein the balance point is approximately equal if the location of the balance point of the tuning point ahead of the front of the arrow shaft when the point is secured to the forward end of the arrow shaft is approximately the same as the location of the balance point of the given broadhead when attached to the forward end of an arrow shaft.

4. A tuning point according to claim 3, wherein the balance point is approximately equal if the locations are within about one-quarter inch.

5. A tuning point according to claim 1, wherein the length of the tuning point is substantially the same as the length of the broadhead.

6. A tuning point without blades for archery arrows, comprising a body;

means for securing the point to the forward end of an arrow shaft;

a weight ring around a portion of the body to increase the weight of the body; and

a forward tip on the forward end of the body;

the tuning point being of a weight approximately equal to that of a given broadhead, and having a balance point approximately equal to that of the given broadhead.

7. A tuning point according to claim 6, wherein the body includes an intermediate portion with the weight ring positioned therearound.

8. A tuning point according to claim 7, wherein the body is aluminum, the weight ring is steel, and the tip is steel.

9. A tuning point according to claim 8, wherein the tip is threaded to the forward end of the body.

10. A tuning point according to claim 9, wherein the means for securing the point to the forward end of an arrow shaft is a threaded rearward end portion of the body to be threaded to the forward end of the arrow shaft.

11. A tuning point according to claim 10, wherein the threaded rearward end portion is externally threaded to be screwed into the forward end of the arrow shaft.

12. A tuning point according to claim 11, additionally including at least one weight collar removably positioned on the body.

13. A tuning point according to claim 12, wherein the at least one weight collar is removably positioned over the rearward portion of the body.

14. A tuning point according to claim 12, wherein the rearward end portion of the body includes a threaded portion and an unthreaded portion immediately forwardly of the threaded portion and the at least one weight collar fits over the unthreaded portion.

15. A tuning point according to claim 14, wherein the intermediate portion is immediately forward of the unthreaded portion.

16. A tuning point for archery arrows comprising a body;

means for securing the point to the forward end of an arrow shaft;

a bore in the body adapted to receive selected weight in the bore forwardly of the means for securing the point to the forward end of an arrow shaft; and

a forward tip on the forward end of the body;

the tuning point being of adjustable weight by selecting the weight in the bore to enable an archer to adjust the weight of the tuning point to be approximately equal to that of a given broadhead, and the tuning point having a balance point approximately equal to that of the given broadhead.

17. A tuning point according to claim 16, wherein the forward tip is removable from the body and includes a threaded rear portion thereof, wherein the bore is a central, internally threaded bore extending into the body from the forward end thereof, wherein externally threaded weights can be screwed into the bore to vary the weight of the tuning point, and wherein the forward tip is removably secured to the body by being screwed into the bore.

18. A tuning point for archery arrows wherein the tuning point has a weight approximately equal to the weight of a given broadhead and a balance point approximately equal to the balance point of the given broadhead, and the given broadhead has a body and removable broadhead blades, comprising the broadhead body with the broadhead blades removed, and weight compensation means of weight substantially equal to the weight of the broadhead blades to compensate for the weight of the removed broadhead blades, the weight compensation means secured to the body in a manner to produce a balance point for the tuning point approximately equal to the balance point of the selected broadhead.

19. A tuning point according to claim 18, wherein the weight compensation means is a sleeve that fits over the broadhead body.

20. A tuning point according to claim 19, wherein the forward tip is removably threaded to the body, and the sleeve is positioned over the body with the tip removed and the tip is secured to the body to hold the sleeve in place.
