Taking stuck rod sections apart

If you have two sections that are stuck, there are various ways of pulling the sections apart.

1. you can try by putting the sections behind your knees, crouch with the rod in the bent section behind your knees, and gripping with either hand on the outside of your knees and forcing your knees apart.
2. you and a friend can take the sections, but make sure that each has a hand on the opposing section - not each one pulling a complete section as you can snap the rod
3. put in a fridge or pack some ice on the ferrule joint. The inner male ferrule will shrink and the female ferrule will shrink "differently" (think about the ball and ring science experiment).
