Thanks Zane,
I managed to get the largest dent out by wooden dollies cut with the correct radius, I had to make them small enough to drop inside the tube through the baffle openings, then once inside, I had to jiggle the tube around till the dollies were in the correct place. then it was just a case of a very long wedge in the form of a large screwdriver inserted between the dollies and twisted, and no more dent.
The hardest part was getting the little blighters out through the baffles.
Luckily I am reasonably patient ( I make sure I have something dispensable nearby so I don't smash the valuable stuff out of frustration )
