The welds on the end will not be very substantial, we want to be able to easily cut through them and fit a new section if we need to. Also there are 2 rings, one at the top and bottom, each with 6 sections (60degree)

The finished item will look a bit like this: armor.jpgarmor.jpg

My thinking at the moment is to get some flat bar and roll it to shape, minus the overlaps. My calculations based off ebay pricing for mild steel makes it about £220, including machining/waterjetting our little joining pieces to the aluminium.
