Alberto Poratelli and Gabriele Gori - Streamlined Bamboo Ferrules

 

 

 

Among the best cane rod makers in Italy are Alberto Poratelli and Gabriele Gori.

Do you remember what Alberto Poratelli was saying about making the "invisible ferrule" in my interwiew?

Well, I think here it is!!!

What can one say about this incredible "invisible" ferrule more than to show it and to be stunned by the simplicity of the whole idea?

Alberto told us his quest for the perfect bamboo ferrule, both esthetically pleasing and technically resistant, his many attempts and failures. Then, he explained that he was almost going to throw the towel when he spoke to his friend Gabriele Gori, an engineer, and Gabriele had this brilliant idea which Alberto put into practice immediately and...voilą!

I think that this was even an historical moment and that Alberto's and Gabriele's method will certainly contribute in the advancement of bamboo rod making. Perhaps one day they will be remembered as the Poratelli-Gori ferrule inventors...

Below is the MOST important drawing of the whole gathering: how to make the Poratelli-Gori bamboo ferrule! You proceed as for a normal bamboo ferrule, then you heat the MALE part with a hot-air gun, which becomes deformable as you know, you tighten it with a cotton thread and the power fibers get the shape of structurally perfect MALE bamboo ferrule!

Alberto explained that they tested the rod and asked Roberto Pragliola, Italy's fly angling Master and guru, to try breaking the ferrule by casting the rod with a #6 line. The attempt showed that the ferrule could withstand the rupture test easily without breaking.

Calculation's of Gabriele Gori (elasticity module) showed that this ferrule is 4 times more flexible than a normal bamboo ferrule and 9 times more flexible than a nickel-silver ferrule!
