Centrifugal Dust Collector
One of my favorite YouTubers made a video about his project to make a centrifugal dust separator for his woodshop. It's a clone of this Harvey dust collection system which, as of the time of this writing, retails for almost $2800US. Naturally, I had to try to make my own. I sized it to fit inside 4" PVC instead of the 6" diameter acrylic tube he used. I don't care about seeing the dust swirl inside and I wasn't about to spend $150 on the tube, either. Operation is pretty simple. Overall airflow is in the direction of the yellow arrow. Lighter dust follows the orange arrow and is spun up by the turbine (which does not actually spin, important to note), causing it to be flung to the outside of the pipe. Heavier dust can't make the corner around the initial stage, causing it to be dumped into the first stage collection bin. At first, I was using a couple of 5-gallon buckets as the collection reservoirs, and a battery powered Ryobi shop vac to do the air movem
