Default Re: Thread: nylon or NCP

NCP mean no color preservative needed. It's still nylon, but the dye is sealed in. The color you see on the spool is the color you will see under the epoxy. It's easier to work with because you can skip the color preservative step but the colors are limited.

Rayon and Polyneon are basically embroidery threads. Much greater selection in colors but you will need color preservative and some colors will darken slightly. The only downfall to using embroidery thread is that the largest diameter available is a 40 weight, which is eqivelant to a size "A". When building fly rods or rods rated up to 30lb test line "A" thread is fine. The only time I use larger thread is when I'm building rods rated above 50lb test.

Any time they can brand an item for a specific task they can charge more money.
650yds of NCP "rod building" thread $6.70
1100yds of Embroydery thread $3.85

It's worth experimenting

The are a bit flat and very opaque.

On the rod I just finished I used ProWrap brand nylon for the tan and green and Fish Hawk NCP for the trim bands. If you look back at that rod build thread you can see the difference in the vibrancy of the colors before epoxy...and after. Nylon thread without color preserver will always have an amount of transparency, so the color will change depending on the color of the blank under it (or any underwrap). Again on my XP I used tan, which looked almost non-metallic gold, but after the finish the green of the blank made it much darker and the guide feet are clearly visible under the transparent thread. If I'd used color preserver, I imagine the tan would have stayed much closer to the unfinished look.

As for the characteristics of the threads and my limited experience with the NCP, I much prefer nylon. The Fish Hawk NCP tended to fray and unravel a bit when making small trim band. Nylon stays in its nice little "rope" no matter.

Other members here like Diver Dan and Swirlchaser, just to name a couple, are incredibly experienced thread masters, if you will. They do amazing stuff and will hopefully give you better and more info.
Dean, those wraps look awesome. Nice choice of colors and I think the Tan looks better the way you finished it, I like a subtle color transition on flyrods.
