A Mandrel and method of using the same to form an elongate rigid guide that has a first elongate portion over which an elastomeric tube may be slid. A second elongate end portion of the guide when axially aligned with the handle of a tennis or racquet ball racquet may be caused to removably engage the same. Anti friction means are provided on the guide to facilitate the longitudinal movement of the elastomeric tube thereon. The handle of the racquet has a transverse cross sectional area substantially greater than that of the interior of the elastomeric tube. After the guide is in engagement with the handle, the elastomeric tube is moved towards the latter. Prior to the elastomeric tube moving onto the handle it is radially expanded to conform to the exterior configuration of the handle. After the tube is mounted on the handle the guide is separated from the handle, with the tube frictionally engaging the tube to define a grip thereon due to the tube being circumferentially stressed.

In combination with a racquet that has a handle of substantially square transverse cross section and an elongate elastomeric tube that has an interior transverse cross section less than that of said handle, a portable assembly for mounting said tube on said handle to define a grip, said portable assembly including: a. a hollow elongate rigid guide that includes a first end portion of circular transverse cross section of such dimensions that said tube may be slideably mounted thereon, a second hollow end portion that removably telescopes over and engages an end extremity of said handle, said second end portion having a transverse cross section of the same shape as that of said handle and larger in cross-sectional area than said first end, and an intermediate portion increasing in cross-sectional area between said first and second end portions to provide a transition portion therebetween; and b. anti-friction means that comprising parallel laterally spaced strips that extend along the longitudinal length of the rigid guide and covers at least a portion of the exterior surface of said guide that permit said tube to be moved and expanded longitudinally along said guide from said first end portion of said second end portion and onto said handle to define a grip, with said guide being removable from said handle after said tube is positioned thereon for subsequent use in mounting elastomeric tubes on other racquet handles.
