I've got a stainless steel ring, approx 100mm in diameter, with an approx 50mm hole in the centre. The item is about 2mm thick. I'd like the hole in the middle to be a bit wider, say 60mm - what's the best method to use in doing this? Doesn't have to be mega accurate or concentric (it's an escutcheon that goes around a steering column on a kit car that was a little too small) so the odd mm here and there won't matter, as long as it looks round by visual inspection
