Nice little trick you can use for wobbly pole jacks… the basic concept is to modify the pole jack so that it has a custom fit with your trekking pole tips. Your trekking pole tip is used to make a molded piece in the end of the pole jack that exactly matches the trekking pole tip.
You will need some JB Kwik, some Vaseline, a tiny piece of closed-cell foam (CCF) and, for clean-up, some rubbing alcohol and some paper towels.
Step 1 – Thoroughly clean and dry the trekking pole tip and then rub some Vaseline onto the pole tip, lightly coating all surfaces that will be inserted into the pole jack. The Vaseline is a release agent that will permit the pole to be pulled out once the JB Kwik has cured.
Step 2 – Insert the CCF down into the pole jack just past the depth of the trekking pole tip when it is fully inserted into the pole jack. The CCF acts as a ‘dam’ that keeps the JB Kwik in the tip of the pole jack, where you need it.
Step 3 – Mix up the JB Kwik and pour it into the end of the pole jack. You only have to fill it about halfway because the trekking pole tip will take up a lot of volume.
Step 4 – Insert the Vaseline-coated trekking pole tip into the pole jack, which will cause some the JB Kwik to ooze out. Wipe this with paper towels and rubbing alcohol to clean up.
Step 5 – Carefully check the alignment to make sure the pole jack and trekking pole are in a straight line and let the JB Kwik cure.
Step 6 – Once the JB Kwik has cured thoroughly, grasp the trekking pole in one hand and the pole jack in the other and gently bend back and forth where the trekking pole tip and pole jack meet. They should separate fairly easily because of the Vaseline release agent.
Note: JB Kwik does indeed cure very quickly, so have all your items ready to go as soon as you’ve mixed it up.
Voila! You now have some custom fit pole jacks!!
