HDD Grinder Stone

In some www I found image of HDD transformed to grinding stone. It was placed in “jokes” category. But I decided, that small grinding machine is useful for hobbyist. I use old 2G HDD “Western Digital Caviar 22500″. It is only 5K rev/minute HDD. Removed cover and all heads, magnets. Took sandpaper and glued to one disk plate.

The engine is quite weak, but this “grinding machine” is usable. Next version will be mad from some quicker drive. I am looking for 7K SCSI Barracuda… Or maybe, if I’ll find, it will be some very old, but powerful, multiplate server hdd.
