Put the evp on then splined the rod. Put the reel seat on last night and re splined it again and it is about 1/8 or so of the main line. With the calstar 800h blank, is this going to cause a torq problem when the rod is loaded? I know there is not much I can do but not let it happen ever again.

Stephen,
If you spiral wrap it torque problems will be non-existent. Randy.

Spinning or acid...you'll never know the difference. Wrap it & don't look back.

When doing guides-on-top rods I try to line everything up on the sp(l)ine (no "L" in the word). When building spinning or acid/spiral rods the spine never even crosses my mind as I build along the straightest axis instead.

Jay,
In the old Clemens books it's referred to as spline. The first time I ever heard or saw in print it called spine was in Don Phillips book, The Technology of Fly Rods, which was published in 2000. No matter how it's spelled it means the same thing. To those who do not believe that the spline (spine) makes a difference when building fly rods should read Chapter 7 of Don's book. It explains in technical terms what it is, the causes and the affects.

Book or no book, I just don't buy that it makes a difference. Just a PERSONAL opinion, but no matter where you put it, it will be in a different position when you cast or retrieve and on a fly or spinning rod, the guides are on the bottom which would negate any torque effect. ITHINK that it's important because some "legend" said it was important many years ago.

This is just MY opinion and I have no technical info to support it but I have seen none that would negate it either. I would build to the straightest axis.

If I don't want to, I don't have to and nobody can make me (except my wife) cuz I'm RETIRED!!

Not aligning the spine or spline is of so little consequence to the performance of the finished rod that it will not be able to be measured by any means.

Those old myths die hard, don't they?

I quit "spining" rods last year......now I build along the "offset radial axis". Sorry, I couldn't help myself.

Hush! Don't tell Emory. He''ll question your sensitivity.

Torque does not come from rod spine, it comes from guide position versus the direction the load is applied from.

Thank you for the help. I really appreciate it.

Call it what you wish, but it can be measured by several means. Very few rods are radially symmetrical. Consequently, if you rotate the rod along its length and measure either its ERN or frequency at different degrees of rotation, you can indeed measure something. The ERN could vary by as much as 0.2 and the change in frequency is noticable. As to what effect that has on performance, it depends upon one’s definition of performance.

I won't have much if anything to do with rod performance, but as Dr. Hanneman said, you can measure it. Provided, of course, that you have a system of measurement that contains enough resolution to record such minor differences. The CCS does, in fact, have enough resolution to do just that. On most freshwater type rod blanks, the difference between the softest and stiffest axii falls into a range of about .2 to .3 ERN.
