Looks like this will do a pretty good job of dealing with a few CDs that you don’t want to ‘fall into enemy’ hands. I have about 150 that I need to destroy, my first thought was a microwave oven with an auto feed attachment to just make it a ‘load and go’ way of dealing with them. Another thought was to glue a stack of them together and then chuck it on a lathe and turn it into something useful. Good concept except that I’ll be gluing the base of one to the thin top cover of the next, I doubt that it would be all that strong. Plus flowing the glue would be a pain.
CDR’s are great things, but what to do about old backups? You can’t just throw them away, lest someone fishes one out of the trash. Breaking them isn’t very satisfying, and they jam paper shredders. Sticking one in the microwave oven is good fun, but the fumes are probably toxic and I don’t have a microwave. I do have this broken 52x CDROM drive though.
