[TowerTalk] How do you separate aluminium tubes that are stuck together ?

Aluminium?   :)

A method I've used with excellent results is to lubricate the aluminum tubes as best as possible, then hammer the end of the stuck tube from the inside of the larger  tube.  This can be done with a slightly smaller diameter tube that slides easiily inside the larger diameter tubing.

I suggest you do not twist the tubes, there's a significant risk of galling and cold welding the tubes if you do.

>Heat, hit with hammer, attempt to twist. Keep doing this until they part. Cursing might ease your feelings a bit during the exercise, which can be quite lengthy - it won't separate the tubes, though.
