Golf head and shaft with flex neutralization and method for manufacturing same

Abstract

A device for determining a neutral point on a golf club head. The device comprises a base. A calibration block is attached to the base. The calibration block comprises an index dial and the index dial comprises a neutral indicator. A head aligner is rotatably attached to the base opposite to the calibration block. The head aligner comprises a groove aligner and a sole plate. When the sole plate is in contact with a club sole of the golf club head and the groove aligner is aligned with a club groove of the golf club head the neutral point is aligned with the neutral indicator.

1 . A golf club head comprising a mark indicating a neutral point.  
   
   
       2 . The golf club head of  claim 1  wherein said mark is an indentation.  
   
   
       3 . The golf club head of  claim 1  further comprising a shaft with a neutral flex point line wherein said neutral flex point line is aligned with said mark.  
   
   
       4 . The golf club head of  claim 3  wherein said shaft comprises a neutral flex point mark corresponding to neutral flex point spine line.  
   
   
       5 . The golf club head of  claim 1  wherein said golf club head comprises a hosel.  
   
   
       6 . The golf club head of  claim 5  wherein said mark is on said hosel.  
   
   
       7 - 11 . (canceled)  
   
   
       12 . A golf club comprising; 
 a golf club head comprising a mark indicating a neutral point; and 
 a golf shaft comprising a neutral flex point mark indicating a neutral flex point line wherein said neutral flex point mark and said mark are aligned.  
   
   
   
       13 . A method for manufacturing a golf club comprising: 
 inserting a golf club head in a device for determining a neutral point on said golf club head said device comprising:    a base;    a calibration block attached to said base wherein said calibration block comprises an index dial and said index dial comprises a neutral indicator;    a head aligner rotatably attached to said base opposite to said calibration block wherein said head aligner comprises a groove aligner and a sole plate wherein when said sole plate is in contact with a club sole of said golf club head and said groove aligner is aligned with a club groove of said golf club head said neutral point is aligned with said neutral indicator;    placing a mark on said golf club head at said neutral point;    inserting a golf shaft wherein a neutral flex point of said golf shaft aligns with said mark.    
   
   
       14 . A golf club comprising a golf club head and a golf club shaft prepared by a method of: 
 inserting a golf club head in a device for determining a neutral point on said golf club head said device comprising:    a base;    a calibration block attached to said base wherein said calibration block comprises an index dial and said index dial comprises a neutral indicator;    a head aligner rotatably attached to said base opposite to said calibration block wherein said head aligner comprises a groove aligner and a sole plate wherein when said sole plate is in contact with a club sole of said golf club head and said groove aligner is aligned with a club groove of said golf club head and said neutral point is aligned with said neutral indicator;    placing a mark on said golf club head at said neutral point;    inserting a golf shaft wherein a neutral flex point of said golf shaft aligns with said mark.    
   
   
       15 . The golf club of  claim 14  further comprising a second golf club prepared by said method.  
   
   
       16 . The golf club of  claim 15  further comprising at least seven golf clubs prepared by said method.
