HSS New System - Bamboo Fly Fishing Rods-en

Both of those rods have advantages and disadvantages.

There is one fact : there are fly rods of great quality as the poor quality, no matter if they made up of bamboo or graphite.

The professionally made and perfectly finished bamboo fly rod would be something that  can be used by the generations.

The great advantage of graphite rods begin to appears  on long rods, 9 foot and longer.

Due to the structure of graphite, these rods are light in weight and cannot be  compared to the Bamboo fly rods.

BUT NOW IT'S A NEWS ... follow me

In first place all Rodmakers have lived to progress regarding some Bamboo Ferrules  and today they are part of the normal building.

In the second place, but no less important, there has been a run to make the lightest rods turning the attention to the hollowing of the same.

The exercise of building rods as light as possible is not an end to itself, but it needs to make such tools faster.

We all know, some more or less, that the speed with which a rod moves is linked to the "INERTIA" value of that.

But what is INERTIA?

- Inertia is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. It is the tendency of objects to keep moving in a straight line at constant velocity … it's our case.

Obviously a value of "INERTIA" higher, lower will be the speed with which we can move the implement.

There are two ways to lower above value including:

Apart known art in the heat treated bamboo where the residual weight is reduced by approx 7%, and considering that the good part and structural Bamboo is relegated to a few millimeters (1 or 2 max) which are located under the enamel, many people have thought of, rightly, to remove the rest of bamboo by making in practice emptying (or hollowing) of the rod.

Also in this case, unfortunately, we have limits because it shall come to terms with the gluing surface. If the latter was in fact extremely small not hold up to the stresses caused by the tool.

Then, go down to below 1.5 -2 mm is not recommended.

We look at the emptying system which is the "sector" most used:

But this is not the best to lighten a rod.

It appeared at the limelight for some years the "star system" and it is on it that it is my intention to focus having, after a couple of years of experimentation, developed the dimensioning according to the various sections of the rods.

It varies from sections for two-handed rods ranging in size (face-to-face) until 12 to 15 mm through the rods to one hand with dimensions up to 9 - 10 mm.

Before get into specifics of the various sizing is good to understand what is meant by "Hollowing Star" and how it is put in place.

Using two utensils plaques for lathe or milling mounted on a suitable support it is removed the inner part of each bamboo strip triangular in order to have

as following this result:

As you can see with the eye, and without making major calculations the surface removed is very big.

Looking at the figure No. 1 we can see that the triangular blades dig a furrow at 60 ° with respect to the base surface.

In this way the outer part of the strip worked "C" has a very large surface area.

This allows us to go down to the limits of the wall thickness of the rod until recently unimaginable, or allowed only to composite materials such as "graphite".

-  I indicate the measurement of 0.8 mm to understand what we're talking about

The Lion's share of this system is up to this "inner wall" without which all the mechanics would collapse.

This wall, whose thickness is the distance between the blades (A), is input in the geometric figure as an element of great rigidity working to "cut" or at 90° with respect to the action of the rod.

Being these rods hexagonal we will find six internal diaphragms which work in opposition with respect to one another, exactly as I wrote above, at 90 ° to the movement of the rod and that's the main thing.

In this case, the weight saving has been higher than 43%
