[QUOTE="Steerpike, post: 804511, member: 807"] It was a sheet of 2.5mm aluminium, crudely cut to an octagon. I made a jig so that my angle grinder was mounted in the right position halfway through a sheet of sturdy MDF board. Then the aluminium was screwed to the same board, with a single tighly fitting screw, so it could be slowly rotated against the grinding disc, thus trimming it to a fairly perfect circle. Size is quite critical, since it must fit neatly into the bezzle around the platter, without scraping, but also with enough metal on the lip to sit firmly and uniformly when it is parked. [/QUOTE]
