Discussion Title...

Hi Everyone, I bought a pole a couple years ago and when I had to take it down I couldn't separate the two middle pieces.  I didn't think anything of it because  I had enough room to put this whole piece in my closet.  I am not moving and would like to take it apart so that it can fit in my car. This is what I tried, suggestion were taken off of the internet. My husband who is not a small person and myself tried to separate it with the tools provided when I bought it.  Putting a ice pack to shrink the metal, using a rubber hammer and giving it a good whack to do a quick release. Any suggestions?   Thanks in advance. Snowflakes
