Conclusion

Swivel Chair and Gun Rest

Problem Statement: Tree stands used for hunting often have a stationary bar that is part of the frame for the stand. This bar only offers mediocre assistance to the hunter and only when he is aiming straight ahead.

Proposed Resolution: A Gun Rest that would swivel from side to side will increase the accuracy range of the gun. By attaching a swivel chair a hunter could also quietly aim at an object.

Scope

An aluminum arm, attached by a bearing to the bottom of a deer stand. The arm must be strong, lightweight, adjustable, camouflaged, glare-free, and absolutely quiet. In addition, a mechanism will be devised to stop the arm and hold it stable for a sound shot.

The swivel seat will aid the hunter in positioning his/her body in a comfortable and stable shooting position. The seat must also be completely quiet and glare-free.

Market

In Georgia alone, for the 2003-2004 Deer Hunting Season, there were 289,703 modern firearm hunters, and 69,078 muzzleloader hunters.

Average deer per hunter: 1.6 This displays the possibility of a huge demand for shooting stability

devices and stands, not only in Georgia, but wherever game is hunted.

Task Assignments Allan: Design seat swivel mechanism. Ensure that the

seat betters the hunter’s range of motion, operates silently, and is durable.

Bill: Design group website, take photos and videos, assist in part designs.

Cleve: Design bearing system for arm rotation. Calculate loading, size, and suitable type of bearing. Create bearing-to-stand attachment.

Craig: Design arm and gun rest. Ensure that the arm is lightweight, durable, quiet, adjustable, and capable of clearing the stand at all points. Ensure rest is quiet and stable.

Josh: Design stopper system. Ensure that the system stops the arm quietly and securely and releases easily.
