I'm going to be building a heavy saltwater rod for halibut and would like to know what size thread I should be using for my under wraps and double over wraps.
What say you, saltwater building dudes? :)

A or even 00 for underwraps, if you choose to use them. Then use D for overwraps.

I'm with Tom,"A" under "D" over

Hi Dave,

Two Schools of thought on this. D overbind is larger an therefore stronger, which is correct. A overbind gives you more threads over the guide foot which is also correct. Probably pros and cons for both. I think thread tension and packing are more important. Binding with both threads with good tension is going to be better than a poor bind with either of the others. You should use as much tension as you can while still being able to move the guides for alignment. Too much and you won't be able to move them. Too little and they'll move too easily. Different types and sizes of thread will need different tensions. It's something you have to work out for what your using. Packing is also important as the better it's packed the more threads you get over the guide foot irrespective of what size thread your using. Personally I use Madeira which is similar size to "A" thread. Use it for both under and overbinding. On 30lb and over I use a double overbind and haven't had any problems.
Choose whatever size suits you best, just get the tension right and pack it well and you won't have a problem.

Thanks a lot fellas.
Now I just have to choose my colours. :)

One more question.
When under wraping and or double over wraping what is the best way to get a good looking wrap?
Do you lay on a coat of finish between layers?

D under, D over

A very thin layer of epoxy on the underwrap is perfectly acceptable. Otherwise, you'll find that using larger thread over smaller keeps the top layer from digging into the first fairly well.

Thanks for the info Tom.

Dave,
You can use any size thread that you want. The actual total strength of the wrap is a function of the number of wraps as well as the strength of the thread being used.
The total strength tends to be a constant. i.e. finer thread results in more wraps. Coarser thread results in fewer wraps.

However, many folks prefer to use the heavier thread for the outer wraps just due to the durability factor. i.e. thicker thread can take more heavy impacts and ripping and tearing at the rail than is the case with finer thread.
This durability factor is one of the major reasons that builders and users of rods use when they specify the use of a heavier outer wrap for heavy boat rods.

Good luck and happy wrapping.

Hi Dave

I use A for underwraps and A for double overwraps for heavy saltwater. I regularly fish in 80 - 120 metres of water for Amberjack, Cobia etc. (Australia) Never had an issue.

When the underwrap is on, I apply a very thin coat of epoxy. Very thin means you can still see the individual threads show through. Then overwrap first layer with A, again a thin coat of epoxy. Then second overwrap and finish as normal.

hi dave , if you are building a heavy (depending what poundage it is) spinning rod i would be inclined to double underbind using A thread in a NCP. (so you don't have to use CP,so epoxy soaks in)
you can do both double underbind than thin coat thinned down with metholated spirits so it soaks right in.than double overbind the guide with NCP, A thread than apply another thinned down epoxy, let cure than second reguler coat of epoxy.
if you are building an overhead, single underbind than double overbind, thin down epoxy first coat and reguler second coat.
you can also use C size thread in NCP, just the A size is a little less bulky with that many layers.

i hope that helps

Thanks for all the suggestions guys. :)

Dave
