You can build a fairly efficient cyclonic dust separator from just a couple CD cases, a toy traffic cone, and some PVC pipe. This dust separator can be attached to a bucket and used with an existing shop-vac. You can also use this CD case dust separator to build a whole shop-vac entirely from scratch that performs just as well, is compact as, and is cheaper than an off the shelf shop-vac. All you need is a couple CD spindle cases, a toy traffic cone, a bucket, some PVC pipe, and a vacuum cleaner motor. A friend challenged me to build something out of a CD spindle case and the first thing that came to mind was a cyclonic vacuum cleaner. Strange but true. A few months later, this product emerged. You can see some video of early prototypes that I made.
