<p>The invention includes a golf club (10) having a club head (14) and a tubular shaft (12) connected to the club head (14). A separate weight (20) having a density higher than the shaft (12) is located within the shaft (12). A material (22) having a rigidity significantly less than the rigidity of the shaft (12) is interposed between the shaft (12) and the weight (20). A method for making such a golf club (10) includes providing a golf club shaft (12) and disposing an expandable material (21) about the weight (20). The weight (20) and the expandable material (21) are inserted into the shaft (12) of the golf club (10). The expandable material (21) is then expanded such that the expandable material (21) expands and secures the weight (20) to the shaft (12). In another arrangement, the weight (20) is co-molded with an intermediate (22) material having a rigidity significantly less than the rigidity of the shaft (12).</p> |
