[TowerTalk] Dismantling an old 40m beam

Yes, but even if both pieces end up at the same high temperature, when they
cool the seized surface between them will probably break loose.  At least
that's been my experience with heating a seized tubing joint.

Since aluminum tubing is thin and it has very high thermal conductivity I
question how effective this method is.

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