THREE-PIECE RODS 109 



It is well to bear in mind that you cannot make 

 each of the other two joints one-third of the 

 total length of the finished rod, for the reason 

 that the tip is to be pushed one inch into the 

 ferrule of the middle joint, and this in turn 

 iy$ inches into the ferrule on the butt joint, 

 while these two ferrules add to the actual 

 length of the two lower parts. 



A more difficult problem in division and 

 addition it would be hard to find. The first 

 time I tried to make a rod of three pieces of 

 equal length I almost gave it up in despair, 

 for despite what I thought was exact calcula- 

 tion, the separate parts would vary or the total 

 would be too great. Finally I drew a pencil 

 mark on the floor just 5^ feet long, and sit- 

 ting down, puzzled the problem out 4 by plac- 

 ing the three parts of the rod, with the fer- 

 rules beside them, on the line, and measuring 

 until the adjustments -were correct. 



The actual length of the middle joint will 

 be 21^4 inches, for the top or female ferrule 

 will extend I inch beyond the wood, making 

 this joint 22 inches when it is finished. 

 Taper the wood from 21-64 to 15-64, it being 

 remembered that the cap of the ferrule is 

 slightly larger inside than the caps of its cen- 

 ters. Cement the ferrule on the small end of
