A few years ago, I was dis-assembling a bunch of old aluminum elements that
were VERY stuck together. I tried the recommended soaking in solvents and
heating up parts. I didn't have much good results. YMMV of course.
I tried something that has worked well for me, so I thought I'd pass it along.
I use a come-a-long to pull them apart.
I set up between 2 trees. I tie a Pipe Hitch to one of the tubes and tie the
other side of this rope to one tree. With another rope, I tie a Pipe Hitch to
the other tube, and put a loop in the other side of this rope. One side of the
come-a-long hooks into this loop.
The other side of the come-a-long is attached to the other tree. Take up on the
come-a-long to tension the ropes. Continue increasing the tension with the
come-a-long until the two tubes separate. Watch out, because the tubes can fly
apart with a lot of force. Don't get your body in the way of a flying tube!
This has always worked for me and the tubing is never damaged.
Have fun and be careful!

Try heating the larger diameter tubing portion close to the joint while
simultaneously cooling the smaller diameter portion which is telescoped inside
of it.
