Proper Thread Tension?

So I've built a few rods now, and I'm getting more comfortable in doing it, but I have a question on thread tension on my wraps. How tight is tight enough? I assume I'm making mine too tight as when I pull tag ends using metallic threads, they quite often shred the foil off of the core, and regular threads can be hard to pull without having to wrap my pulling loop around my fnger a couple of times. I think this may be to much tension, but my mind still tells me that tighter has to be better for keeping my guides stable. Is there any general rule for how much tension should be on a finished guide wrap?
Thanks much. Re: Proper Thread Tension?

After the guide is wrapped, you should be able to move or shift it slightly with gentle pressure. Neither tight, nor loose. Snug is a better word, I suppose.

Tom's absolutely on point here. You need to be able to move the guide just ever so slightly in order to obtain a perfect lineup from stripper to tip.
Unfortunately, the feel for the tension it takes depends partyl on the rod surface, as well as the exact threadd you are using, and yes, itt can vary not only from spool-to-spool in the same brand but even from type-to-type (i.e., NCP /vs/ uncoated, regular ccolor /vs metallic), and even color-to-color in some brands of thread. It just takes practice and patience to get it down. Please don't get frustrated with it. It's worth it when you get it right. Uncle Russ Calico Creek Rods Re: Proper Thread Tension?

Travis,
Good Question, and one I believe everyone has while progressing in the art of rod making. If you don't have a mentor to show you exactly how tight is enough, then how do you know? You say you are more comfortable with your rod building. Well I believe you have reached another milestone. At least that's how I felt when I finally understood how tight was tight enough. Things just seemed to get easier after that. From what you say above you are very much to tight. Do you remember reading of very simple rod twisting devices, about how you could put the thread in a cup, and then run the thread through a book for the proper tension? As simple as this system seems, it's a tool I'll use at times wrapping multiple threads, like for a tiger wrap, or even an inlay. You can do a search in the photo directory and see many tension devices designed and used, all probably good for their intended purpose. But the one I like the most, and the one I think really gives you a greatest clue on proper tension is this one by Mike McGivney. [www.rodbuilding.org] Some one jump in and correct me if I'm wrong in this statement, the strength of your guide wrap is cumulative. Another words if your thread is rated at 2.2 lbs. and you wrap 10 wraps the strength will be somewhere around 22 lbs.[www.gudebrod.com] Nylon & NCP® Rod Building Threads. Instead of cranking your thread tension device very tight and then trying to go looser and looser. I would relax my tensioning device until just before it falls apart, and gradually increase tension from there. The self taught learning curve can be a long one, I believe there is light at the end of the tunnel. hope this helps floyd Re: Proper Thread Tension?

I just pull the thread until it feels right. How much is "right" well that's hard to say. But I think the word snug was used and that's how I'd describe it. Just snug. Once wrapped if you can't move the guide at all its way too tight. If you can shove it all over the place, it's too loose. Anywhere in between is going to be just about right.

Travis,
When using metallic thread, put the tag into your tie-off loop, pull the loop until it just touches the wrap, then clip your tag to about 1/2-3/4" before pulling it through. Longer tags will twist more, as you pull them through, causing the foil to unravel. George Re: Proper Thread Tension?

I've found using mono as the pull through removes most of the issues with metallic thread - 6lb Trilene. Sorry, only registered users may post in this forum.
