Hi all,
Thank you all very much for your input and as expected the aluminium pole isn't an option, so I am going down the route of fibreglass tube with wood insert.
Just need to source a UK company that can supply the tubing! I have contacted Engineering Composites and will await a price!
All the best!

Chris,
As has been pointed out, an aluminum liner won't work. I have a fiberglass tube, and found a solid wood rod at a local building supply store. It is a perfect friction fit. I cut it about 2 inches shorter than the tube, leaving about an inch space at each end. I stood it on end, and filled one end with RTV. After it hardened, I swapped ends and sealed the other end. It has been in use for almost 15 years with no failures or leakages.
