24 AMATEUR RODMAKING 



eter for round rods, and .16 of an inch on 

 each side of the triangular sections of glued- 

 up hexagonal rods. The tests were for resili- 

 ence, deflection, number of vibrations before 

 coming to rest with various weights, specific 

 gravity, and breaking strain. The best results 

 obtained, in the order given, follow: Double 

 enamel glued cane, steel centered; double enam- 

 el glued cane; hexagonal glued cane, steel cen- 

 tered; hexagonal glued cane; greenheart, built 

 up ; hickory, built up ; round greenheart ; lance- 

 wood. 



In theory at least it would seem that in a rod 

 wound with narrow steel wires, these would 

 constantly shift with the spring of the rod, re- 

 laxing in hot weather and contracting on cold 

 days, the general effect being to shear windings 

 and varnish, and to rust. Certain it is that one 

 of the British firms which adopted steel rib- 

 bing some years ago, now advocates a braided 

 silk sheath to cover the steel. 



A Frenchman has made rods in which flat 

 steel strips have been let into the wood, and 

 my impression is that a British manufacturer 

 has adopted the invention. 



Some years ago a Scotchman invented a 

 similar method, but he used fine piano wires 

 instead, one being let into each of the six strips
