Claim:
An archery arrow flight test device for testing and tuning trueness of flight of arrows, the device comprising: an arrow test stand for tuning arrow flight which comprises a vertical frame structure, adjustable height legs supporting the vertical frame structure at a desired height above the ground; a roll of paper rotatably attached to the vertical frame structure adjacent to a first side of the vertical frame structure; a roll clamping pressure bar slidably attached to the vertical frame structure adjacent to the first side of the vertical frame structure adjacent to the roll of paper and parallel to the roll of paper for normally pressing against the roll of paper along the entire length of the roll of paper to prevent movement of the roll of paper and alternately being released by a user from the roll of paper to allow dispensing of the paper from the roll of paper; a paper receiving ridge rigidly attached to the vertical frame structure adjacent to a second side of the vertical frame opposite the first side and spaced apart from the roll of paper, the paper from the roll of paper stretched over a forward edge of the ridge facing an archer; a paper end clamping pressure bar slidably attached to the vertical frame structure adjacent to the second side of the vertical frame structure adjacent to the paper receiving ridge and parallel to the paper receiving ridge for normally pressing against the paper along the entire width of the paper pressing the paper against the paper receiving ridge to stretch the paper taut between the roll of paper and the paper receiving ridge and alternately being released by a user from the paper receiving ridge to allow a new section of paper to be dispensed from the roll of paper and stretched over the paper receiving ridge; and a pair of tension elements stretched between the roll clamping pressure bar and the paper end clamping pressure bar on the aligned ends of the bars for normally pressing the roll clamping pressure bar against the roll of paper and normally pressing the paper end clamping pressure bar against the end of the paper stretched over the paper receiving ridge; thereby forming a renewable taut smooth unbroken paper surface for receiving arrows shot therethrough for testing and tuning for trueness of flight of the arrows by observing a hole made from the point and shaft of the arrow and tears made by the arrow fletching passing through so that if the arrow flies straight, the fletching tears are equally spaced around the shaft hole and if the fletching tears are right, left, high or low relative to the shaft hole, tuning by relevant adjustments can be made to a nocking point on the bow string or the arrow rest or both to readjust the flight of the arrows until trueness of flight is achieved.
