'Robh'. just don't write to the press in Green Ink, they think it Kookish. 
'Zanash'. looks interesting, and not to difficult to build one similar methinks, could also be relatively easy to *bevel the edge of a disk at 36 degrees*,without lathe...perhaps a power drill set in a vice with the Cd attached firmly to chuck then a good cutting edge to bevel.
is the cutter in the link as yours..($699

'Barty'. I now have the CD tightly sealed in bag and in the freeze..the time you gave *2 days in a freezer bag in my chest freezer, then a further 2 days in a tea towel in my fridge then 1 day in its case left open in my lounge *, have mostly noted a 1 day in freezer, was the 2 days (Freezer/Cooler) personal choice (preferred for better results) or quoted.
Thanks !
