Abstract:
An archery arrow testing apparatus which comprises a pair of upright arrow support stands. The apparatus further includes a pair of wooden or plastic pedestals. The stands each have a pair of spaced apart thin flat upright legs. Vertically extending slots are provided in the wooden pedestals. The slots are sized to receive and support the thin flat upright legs when the legs are engaged in the slots. An adjustably mountable rod is mounted in horizontally extending holes in the pedestals with opposite ends of the rod engaged in the holes connecting the pedestals together in a supported upright position. Archery arrow testing means is provided which comprises sets of revolving thin metal discs. Means is further provided for mounting a series of the discs in pairs on each of the pedestals with the discs being rotatable relative to the pedestals enabling an archery arrow to be spun in circumferential orbit on the discs for a human eye to scrutinize to ascertain trueness of an orbiting archery arrow.
