RE: CD/ disc scratch repair (not sure if right forum)

Come to think of it I have a binocular microscope here that goes up to 80x that I could give a look

I once ground a telescopic reflector glass - 8 inch diameter - which was fascinating as to the precision obtained and of course it was necessary to maintain uniformity of the grind - a concave surface - not too relevant I think to the CD that doesnt require uniformity across it, as long as you have clarity (I think)

But you are right as to the heat issues and such. Dremel abrasion is also interesting in that lower speed with certain grits works better than higher speed in which I think the abrasives start to plane over the material rather than bite into it and level it
