Abstract
A test apparatus determines the state of torsional balance of an elongate device about its longitudinal axis. It has a base plate, supporting two sets of longitudinally spaced-apart low-friction roller bearings. The second bearings are mounted on the base at a higher location than the first bearings. A support for the second bearings has a side opening to allow lateral movement of the device under test into engagement with the underside of the second bearings which resting on the upper side of the first bearings. The device under test may be a rifle or a golf putter, the barrel or shaft respectively of which is supported on the roller bearings of the first set and in contact with the underside of the second bearings. The device will rotate about the longitudinal axis if not balanced about the axis. It is very easy and convenient for the user to place the tube in the guide to check for balance whenever checking balance of the item. The side opening allows use with a variety of devices having irregular shapes along its length.
