Step 6: Final assembly & test run
Now I can put the plastic bucket over the metal one, hold the together with the standard metal buckets holding clamp that comes with it. Fit the vacuum's flex hose to the center joiner pipe and the secondary flex hose (I found that one from a thrown away vacuum) which is going to suck the dust through to the side joiner pipe, turn on your vacuum and let the cyclone run. All the dust ends down to the metal bucket leaving your vacuum clean and powerful to keep on going.
Remember when you will empty the dust from the metal bucket to ware some mask for protection, after all we don't want to breathe any of these nasty stuff at the end.
