Use of CP

Am presently doing a rather involved cross-wrap where the threads have a tendency of moving as I go from pass to pass despite my every effort to ensure they don't. After doing a search of the Board looking for advice I read that using a drop of CP will help hold threads in place as the wrap progresses. My question is can you use to much CP? I don't mean applying it after every pass, but rather when one thinks it should be used to keep things in place. Could the CP build up to a point where it would affect the look of the finish?
Can't find an answer either on the Board or in the literature I have read, which makes my think the answer is no, but I wanted to check. The answer is probably obvious too many, but as this is my first rod very little is obvious to me at this point, until I do it or ask the question. Thanks for any and all advice.

To me it sounds like the tension of your thread is to light
Try more tension Put on 5 to 8 threads and then pack them Welcome the the world of building rods And this board There is also a search funshion up above that you can find many posts Just mark it at All Dates and type in your question Bill - willierods.com Re: Use of CP

It's possible, but not altogether likely. Just use a single drop in spots. Because of the amount of thread you have on a cross wrap, it's not likely you're going to get much build up above the surface.

I've never seen the need to do something like this. I feel it's counterproductive to achieving the best results in the long run.
You want to be able to move threads around, especially in complex layouts. You need to adjust the location of crosses from time to time as you go, and you need to pack threads between major steps in the layout. How can you do this effectively if you've glued stuff in place? Apply threads one at a time only when you want to or have to, but otherwise wrap in bands whenever you can so the threads can move more freely and I think you'll find your problems you are experiencing will disappear as you add more thread past the problem spots (assuming your layout is correct). Also, if you spot CP then you will have to CP the entire wrap or you will see the spots. If you weren't intending to CP the entire thing, then this will certainly pose problems. Re: Use of CP

Thread in a cross wrap moving is either due to too much or not enough tension. In my experience the culprit is usually too much tension. Re: Use of CP

If you use too much CP at any stage, you are liable to find that the threads will not rest up against each other. I have done quite a few crosswraps, not nearly as many as others on here, but I have never had to use CP to keep the threads from moving. That sounds more like a tension issue. If you were to CP them in place, it may bite you towards the end when you are adjusting your threads so everything is packed. Saying that, once the wrap is completed, everything is in place, I do know guys who use CP to lock everything in before they attempt a tie-off. But, that is only when everything is exactly how they want it already and CP is used just to keep a catastrophe from happening when they cut the threads when tying off. Go back and rethink the tension of your wrapping threads. Sorry, only registered users may post in this forum.
