I had problems separating the aluminum tubing of my A3S boom. It was
incorrectly assembled WITHOUT NoAlox or other anti-corrossion compound.
(I've since learned better)
Best advice I got was to use HEAT. Heat the joint up with a propane
torch, then let it cool slowly. The heat/cool cycle tends to get the
surface corrossion to break off, allowing you to separate the joint.
Don't use too much leverage. After all, you wouldn't want to bend the
tower sections.
