Has anyone had any experience using some type of adhesive to stabilize the plastic weight tubes inside carbon shafts, to reduce the incidence of nock loss?
I recently had to send my current bow back to the bowyer for repair (after 12 years of hard use), so I resurrected an old Kodiak and dug a random bunch of arrows out of of the "archive". I had installed the 3 grain/inch tubes, way-back-when, and remember frequently watching nocks flying off into the leaf litter, whenever the stump was more solid than I expected. I hypothesized, then, that the tubes were rebounding inside the shafts against the nocks, and abandoned their use.
The old bow shoots the old arrows just fine, but nocks still fly. I am considering putting some type adhesive around the weight tube before sliding into the shaft to see if it would fix the problem.
Any thoughts or experience?
when i used to use weight tubes i would use pliers to crimp the tube just enough to deform the tube so that it it tight inside the shaft when inserted. i used to crimp it every couple of inches with each crimp being 90 degrees offset to each other.
worked well for me.

done this or similar things works well
The most effective method I have found over the years was using one of those glue sticks meant for gluing paper. I would apply it to the weight tube as I inserted it in the shaft It would dry pretty quickly and I never had a nock pop off due to the weight tube moving. If I wanted to remove the tube I could do it without much effort or damage to the shaft. The arrows so modified were/are shot out of 60-65 # Widows among others.
Thanks a lot, folks for all the ideas. Can hardly weight to get my "main" bow back.
I tried lots of things to keep them in the shafts back in the day. I have since dropped down in weight to the mid 60 lb range and no longer need any type of tube. I have found that I got better flight with arrows that I could put all my weight up front and not use the tubes.
We used to stock them, but I talked everyone out of buying them so I wasn't making any money having them.

I did the same, also, Jim. Brass inserts and forward tapered shafts worked better. So does Doug fir.. :bigsmyl:
Wood arrows. Problem solved. Only joking. Interesting issue and solutions.
I have wrapped Scotch tape around the outside of the weight tube to snug the fit. It only takes a couple wraps. I wrap them every 4-6 inches and especially on the ends of the weight tube. This makes it tight and prevents that annoying rattle. You can pull the tube by screwing a decking wood screw in the end of the weight tube and gently pulling it out. If you are stumping with these a lot, you will also need some glue on the end of the insert and probably the nock.
I don't shoot any type of weight tube but do get the nocks to pop out if I hit a real hard stump or tree.
I find that the energy and vibration just run back through the arrow shaft and cause the nock to come out. Try twisting the nocks. I would suspect that they turn easily.
