How much does an affixed guide weigh?

Graph 1 – Weight of affixed Guides

affixed guide weight

In my previous post, I note different weights of a guide, but how much does an affixed guide have on a rod section, relative to the section.  So using a sample from the damage SAGE RXPLXi 9wt rod, I affixed 5 guides in a small section to measure the impact of

  • Guide
  • Thread – Small Silk
  • Colour Preserver – Al’s – 3 coats
  • Epoxy – ProKote – 2 thin applications (using acetone to thin)

On a 5″ section to a typical rod top.

From this measurements, I also been able to create a model that assumes when all is equal (rod section, size of wrap, et cetera), provide a comparative look  of the guides static relationship to a fly rod top.  So what is the relationship …..

Graph 2 – The original measure-calculated static weight model – Hopkins Holloway Large Standard Guide – HSSG 2

HHSG2

The HSSG2 is the heaviest guide I would use and reflects the common recommendation in the mid-90s to use larger guides for shooting line (which I no longer agree with). Clearly, the greatest weight is the rod blank (or a fly line), but it s the guide that has the greatest impact.

And yes, the colour preserver had no measureable weight.

.

Graph 3 – Using my old standby H&H, but a size reflecting my standards today – HSSG1.

HSSG1

Not as obvious in this page, but moving from a Size 2 to Size 1, the guide itself is 25% lighter.

Though, I have to ask, why not a smaller or lighter guide. Need to think about this, but I am incline to believe we get to a point where the impact of the guide weight is not as significant relative when we include the fly line (or how the guide is attached -double versus single foot).

.

Graph 4 – Getting lighter – Still with H&H, but using a light Size 1 Guide – HSSGL1.

And now we weight of the thread and epoxy exceeds the guide.

Figure 5 – Changing to Snake Brand Size 1 – SBSG1

A good standard for a like double-foot snake guide.

Figure 6 – REC’s RECoil Titanium Snake Guide – RSN1

rsn1

Ligther and finer, but if you really want to save weight, eliminate some thread and epoxy and go to a single foot guide.  Note from the datasheets from REC, RSN1 has the same loop diameter as RSF2 (and the same weight too).

.

Figure 7 – REC’s RECoil Titanium Single Foot Guide – RSF2

rsf2

So, if you need the lightest rod, yes, go with the RECoil RSF single foot guides, otherwise, my emerging standard is likely to focus on Snake Brand Guides, Size 1 at the top (or maybe smaller).

What about Fuji Ceramics?  Nothing wrong with them (as clearly proven on my Sage RPLXi 9wt), but as illustrated below with the light TLSG8, the static impact is higher.

  1. would have been interesting to look at how the Minima 4 compare to the rest, and maybe a standard and maybe a H&H single foot.

    • I have not heard of the Minima 4 before, but I have since picked up a couple of single foots, and have not yet weighed them. As work is keeping me on the rod for the month, probably will not be able to get back to this until November.
