I think that I have kind of a unique dust collection system so I did a separate video on just it.
What makes it different from most is that I built it under the concrete slab. I was able to do this because I designed and built the shop from the ground up for just being a wood shop. I wanted to do this for a couple of reasons. the first and foremost is not to have a bunch of pipes all over the walls and across the floor.
I put pipes under the concrete going across the floor from left to right in straight runs. Just an elbow at each end, The reason is just in case something gets stuck, it’s easy to clear out. If it’s too long to get around the elbow I can just reach in and take it out. I can’t really see anything getting stuck in the middle of a straight run so if it does get plugged with anything it will be at either the beginning or end at the elbows. If by chance something did get stuck in the middle I could run an electricians fish tape through the jam and out the other end, and then attach something and pull it back bringing back the jammed up stuff.
I ran pipes along the bottom of the walls, front to back so that I could make all the attachment points I needed. They are a few inches off the floor making it easy to clean around them.
I have two outlets pop up in the center of the floor. One for the tablesaw and the other behind my workbench. The one behind the workbench is not being used yet, but I plan on putting a downdraft sanding station there. I also ran electrical wires there for power.
It’s real nice not having either pipes or wires across the floor of dropped down from the ceiling.
