Golf trainer system and method


An adjustable golf swing training device for use with multiple different golf clubs having a template frame partially surrounding and defining a ball hitting area. A club selection bar slidably cooperates with the primary longitudinal frame section so that movement of the club selection bar with respect to the primary longitudinal frame section aligns the club indicia for one of the multiple different golf clubs with the club face alignment tab and establishes the location of the front foot marker and the back foot marker to inform a user of the proper foot locations for the golf club when a golf ball is positioned in the ball hitting area and aligned with the club face alignment tab..

Method of forming a cured elastomer and golf balls


A cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature t1 in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature t2 and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at t1, the second initiator has a half-life of about 0.2-5 minutes at t2, and t2 is higher t1 by at least about 30° c.; or (ii) the second initiator's one-minute half-life temperature is at least about 30° c.
