Buscis2 thanks, that pretty much explains it except which side is the bevel? Is the label side or read side larger in dia after beveling? I'll give this a try with Steely Dan's "Two Against Nature" since I have a couple of them.
I followed your link and if this works for you that's fine. But I looked up aluminum alloys in Machinery's Handbook and aluminum is alloyed with copper, silicon, Manganese, Magnesium, or Chromium. Alloying composition listed down to .06%. So any iron impurities would be less than .06%.
Have you ever tried to magnetize aluminum foil? Okay, I am stupid enough to be sucked into trying this. Although I don't have a pulsed capacitance magnetizer I can get high enough to prove (to myself at least) whether it can be done.
Yes you could use a CNC turning center. You could also use an NC milling machine with a bevel cutter and interpolate a circular cut. But the point I was making is that the same job could be done for less money than your typical "audiophile" equipment.
Yes I radially polish the disc using a microfiber lense cleaning cloth from Walmart ($1.99) and Novus #1. A little heavy breathing to fog up the CD shows up areas that need further polishing. Vocals, for example, are clearer using Novus than just a plastic cleaner alone IMS. I did not like other polishes like Mapleshade Microsmooth as it put scratches in the CD. Novus doesn't.
