Clad surface arrow construction

Abstract

A shaft construction comprising a forming tool manufactured by known means to which is clad an exoskeleton comprising a substantial portion of the shafts strength and other visual and mechanical characteristics.

1 . A shaft construction comprising: 
 an integral forming tool;    an exoskeleton of substantially rigid material clad to the surface of the forming tool;    an exoskeleton providing a substantial portion of the total shaft strength.    
   
   
       2 . The shaft of  claim 1  in which the forming tool may include features such as ribs, holes threads, splines, logos, bulges, indents or the like.  
   
   
       3 . The shaft of  claim 2  which after cladding includes the possible features as unitary parts of the finished shaft.  
   
   
       4 . The shaft of  claim 1  in which the forming tool comprises a substantially hollow tubular shape.  
   
   
       5 . The shaft of  claim 4  in which cladding forms an exoskeleton over portions of either or both the outer surface and the inner surface of the forming tool.  
   
   
       6 . The shaft of  claim 4  in which the inside bore of the hollow tubular shape may include features such as ribs, threads, splines, bulges, indents, holes or the like  
   
   
       7 . The shaft of  claim 6  which after cladding includes the possible inside features as unitary parts of the finished shaft.  
   
   
       8 . The shaft of  claim 1  in which the thickness of the exoskeleton is controllably varied to give different but chosen wall thicknesses at different locations of the shaft.  
   
   
       9 . A method of shaft manufacture comprising: 
 producing a forming tool using known manufacturing techniques;    cladding the forming tool to produce a high strength exoskeleton using known cladding methods;    cladding the forming tool such that the resultant exoskeleton forms a substantial portion of the final shaft strength and other physical characteristics.
