Cyclonic Centrifugal Separator

I’ve made this separator to prevent sawdust from going towards hoover. The separator does its job and collects anything heavier than air and keeps them in the tank.

I've drilled the bowl in order to get the dust inside the tank. And drilled the upper cap from the center and from near the edge, both evenly.

The central pipe is for the hoover and the other one -close to the edge- is for the actual hose.

It works great. Nothing goes to hoover's bag, everything is collected inside the separator's tank. Also very easy to empty.
