Abstract: A device and method to position a newly installed grip or to verify the position of one previously installed, quantitatively, in relation to the leading edge of a golf club head or any point referenced by the alignment assembly. The invention includes two components. The first component is an alignment assembly, removably attachable to the shaft for identifying the position of the shaft diameter that is substantially parallel to the leading edge of the golf club head. The alignment assembly is comprised of an alignment rod and removable pointer both mounted on a support providing a substantially planar surface. The second component is a shaft rotation gauge, removably attachable to the shaft for measuring the deviation of any point on a grip or shaft from any position referenced by the alignment assembly. The shaft rotation gauge is comprised of an arched ruled indicator surface attached to and radially extended a predetermined distance from the shaft axis.
