My last set of CF hiking poles lasted about 3 years. Some extraordinary hiking conditions caused me to break both poles on one trip and one I broke twice on that trip. Fast forward a few weeks and I broke the tip of one of my brand new poles. An upgrade was deemed necessary. From past experience I knew that the carbide inserts were knurled and press fit into the plastic tips. They were just a vessel for crimping around the carbide insert to be held in the pole tip.
I had 3 pole tips snap off right where the insert ended in the pole. I decided I could weld a grade 8 bolt shank (I cut off the bold head.) to the end of the carbide insert lengthening it by a couple inches. Then I figured if I filled the all the interior space of the pole around the bolt with high strength epoxy it would strengthen the tip tremendously. When done I had added 20g of weight to each pole, significantly more than I planned on and needed to. The epoxy fill goes up 6 inches from the bottom of the pole-the interior volume is much smaller that I planned for as I only intended ti fill about 3″up. I’ll update this thread in a few months with longer term thoughts.
