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

[Robert Thain]

Hello,
 
How do you separate aluminium tubes that are stuck together ?
 
We have a 2 section boom  that we want to separate but the pieces are stuck together. The boom is joined at the centre by a smaller tube that goes inside the outer tubes (the boom). (The boom sleeves the smaller fixing section in the middle.) We easily removed the bolts but the 3 pieces of tube are stuck together. The antenna is only a year old, but we did not protect the surface before assembly. 
I fear that it may be corroded together.
So, how do you separate aluminium tubes that are stuck, without damaging them. 
 
I've looked back through the archives , but did not find anything......
 
Thanks
