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.
