thanks for posting this.

You are welcome, I was not the original poster of the link just thought that it was informative enough to place the link in a sticky

I read most of this and it made my head hurt. What I gleaned from the artilcle is a good fitting rear guide reduced spring fatigue.

That's what I mean when I say twang doesn't make me miss. A spring unloading is suppose too twang. Never notice it anyway but I'm about deaf.

Wow, very informative article, thanks for sharing the link.

Thanks for sharing the information.  I found it a bit too much to absorb in one sitting but interesting nonetheless.

Thanks, Thomas I had not been on the forum for very long and kept seeing posts that stated that the main spring and seals were considered consumable items, and being the head-scratcher that I am needed a more in-depth explanation.

I felt like the analysis was a bit over simplistic.  Still hard to read.  I would like to se the springs twist and dimension change during compression and extension to also be considered.  The “fit” to a guide is dynamic in my view. Also the spring buckling also causes variations in friction. Quite complex. Experiment and testing would provide the experience needed to produce something akin to optimal performance.
