![4 Port Manifold Dust Collection](https://www.woodworkersjournal.com/wp-content/uploads/Four-Port-Dust-Collector1.jpg)
I wanted to have dust collection for my Bench top tools. I built this 4 Port Manifold for my shop vac and added a Auto Switch. Now when I turn on any of my Bench top tools the Shop Vac turns on and I open the appropriate gate for effective dust collection.
