<\/a>\u201cThat\u2019ll buff out\u201d is very often true when it comes to disks.<\/p>\nwell cared for. If not well cared for, well, it\u2019s only relatively durable, and we\u2019ve probably all picked up a second-hand disk that\u2019s too scratched to use. The X-Box 360 is notorious for causing circular damage, and while decent disk cleaners were easy to get in the 90s, we\u2019re not sure how far we trust what\u2019s on offer at retailers today. Hence [Dennis], aka [RetroGameRevival]\u2019s RGR ezBuff polishing machine<\/a>, which does exactly what it says on the tin: buffs disks to a polish, easily.<\/p>\n We\u2019d say the whole thing is 3D printed, but of course you still need a motor and controller \u2014 if you had to turn a crank, that would just be a Buff polishing machine, no ez \u2014 and we\u2019ve yet to see a printer poop out polishing compound. If you build it, keep in mind that you\u2019re taking the top layer of material off the disk to polish scratches away, so don\u2019t overdo it. It\u2019s entirely possible to ruin a disk beyond repair with too-aggressive buffing; it\u2019s also possible for disks to be scratched too deeply to save. Polishing can\u2019t save genuine disk rot, though in our experience you\u2019re more likely to find scratched disks than rotten ones. Still, [Dennis]\u2019s birthday gift to the community \u2014 it was apparently released on his birthday \u2014 should keep more than a few disks out of the trash.<\/p>\n With Sony getting out of the disk game<\/a>, physical media is becoming more precious than ever, so it\u2019s good to see what looks like a quality polishing option for those of us who either never had a polisher or didn\u2019t save theirs. If you really want your disks to last, maybe we should bring back CD caddies<\/a>.<\/p>\n
