Method of making a weighted golf swing trainer

Abstract

A method of making at least two types of weighted golf swing trainers. In a first type of trainer club, a lower section of a hollow golf shaft is filled within a first type of particle and a flowable material. A barrier is then by created to keep the flowable material and the first type of particle in the lower section. A second type of particle and a compressible epoxy resin is placed into an upper section of the golf shaft so that the resin cures to surround the second type of particles. A method of making a second type of trainer club where flowable materials are impermissible. Such second club is made in a similar manner as the first type with the exception that the first type of particle and flowable material are mixed with compressible epoxy resin and placed into the lower section of the golf shaft.

1 . A method for manufacturing a weighted golf swing trainer comprising the steps of: 
 (a) selecting a hollow shaft having an upper section, a lower section, a grip end and a head end, the lower section being closer to the head end than is the upper section, the upper section between closer to the grip end than is the lower section;    (b) placing a first type of particle in the lower section of the shaft and whereby there are interstices between the particles;    (c) placing a flowable material in the lower section of the shaft to fill in at least some of the interstices;    (d) forming a barrier between the upper and lower sections of the shaft;    (e) placing a second type of particle in the upper section of the shaft; and    (f) placing a compressible epoxy resin into the upper section of the shaft so that the resin cures to surround the second type of particle thereby.    
   
   
       2 . The method as in  claim 1  wherein the flowable material is tungsten powder.  
   
   
       3 . The method as in  claim 2  wherein the first type of particle is a different size than the second type of particle.  
   
   
       4 . The method as in  claim 3  wherein the first and second types of particles are lead shot.  
   
   
       5 . The method as in  claim 4  wherein the interstices formed between the particles of lead shot in step (a) are 8 g/cc.  
   
   
       6 . The method as in  claim 1  wherein step (d), the barrier formed between the upper and lower sections of the shaft is a liquid impermeable barrier.  
   
   
       7 . The method as in  claim 6  wherein step (d) further comprises the steps of: 
 (1) placing the liquid impermeable barrier into the grip end; and    (2) compressing the liquid impermeable barrier against the first type of particles and flowable material.    
   
   
       8 . The method as in  claim 1  wherein after step (a) but before step (b), further comprising the step of attaching a golf club head to the head end.  
   
   
       9 . The method as in  claim 8  wherein attaching the golf club head to the head end further includes the steps of: 
 (1) abrading the head end;    (2) cleaning the head end with a solvent;    (3) drying the head end;    (4) applying an adhesive to the head end and the golf head; and    (5) inserting the head end into the golf head.    
   
   
       10 . The method as in  claim 1  further comprising the step of: 
 (g) attaching a grip to the grip end.    
   
   
       11 . A method for manufacturing a weighted golf swing trainer comprising the steps of: 
 (a) selecting a hollow shaft having an upper section, a lower section, a grip end and a head end, the lower section being closer to the head end than is the upper section, the upper section between closer to the grip end than is the lower section;    (b) mixing a first type of particle, a flowable material, and a compressible epoxy resin together to form a mixture therefrom;    (c) placing the mixture in the lower section of the shaft;    (d) forming a barrier between the upper and lower sections of the shaft;    (e) placing a second type of particle in the upper section of the shaft; and    (f) placing a compressible epoxy resin into the upper section of the shaft so that the resin cures to surround the second type of particle thereby.    
   
   
       12 . The method as in  claim 11  wherein the flowable material is tungsten powder.  
   
   
       13 . The method as in  claim 12  wherein the first type of particle is a different size than the second type of particle.  
   
   
       14 . The method as in  claim 13  wherein the first and second types of particles are lead shot.  
   
   
       15 . The method as in  claim 14  wherein the interstices formed between the particles of lead shot in step (a) are 8 g/cc.  
   
   
       16 . The method as in  claim 11  wherein step (d), the barrier formed between the upper and lower sections of the shaft is a liquid impermeable barrier.  
   
   
       17 . The method as in  claim 16  wherein step (d) further comprises the steps of: 
 (1) placing the liquid impermeable barrier into the grip end; and    (2) compressing the liquid impermeable barrier against the first type of particles and flowable material.    
   
   
       18 . The method as in  claim 11  wherein after step (a) but before step (b), further comprising the step of attaching a golf club head to the head end.  
   
   
       19 . The method as in  claim 18  wherein attaching the golf club head to the head end further includes the steps of: 
 (1) abrading the head end;    (2) cleaning the head end with a solvent;    (3) drying the head end;    (4) applying an adhesive to the head end and the golf head; and    (5) inserting the head end into the golf head.
