Re: Dealing With Stuck Ferrules
The reason you can't get a rod section apart is that a vacuum develops in the hollow section. When you put the rod together, the air pressure inside the rod section and outside were equal. As the day warms up or if you store the rod together in a hot car, the air in the rod section expands until some of the air leaks out. As the rod cools, the air in the rod contracts and seals the ferrules together even tighter so that they seize. Waxing the ferrules does not allow the sections to seize.
To break the seal, you need to cool the ferrule so that the female and male sections of the ferrule contract at a slightly different rate. This will break the seal and equalize the pressure
If you can't put the rod in a freezer, the best way is to get canned air. You can get it a Best Buy or Office Max. It is pressurized air or CO2 to blow dust off of electronic parts.
Turn the can UPSIDE DOWN and spray over the ferrule, overlapping on both sides. The compressed gas will come out as a LIQUID and as it evaporates, it will cool the ferrule. It will get so cold that frost will form. Then pull the joint apart.
Try the canned air if the frozen pea method does not work. It works on the same principle but canned air gets the joint much colder.
