I was so excited on how well this worked that I just couldn’t wait to post this project. This is my version of the Thien Dust Separator. It worked better then I even expected so I was just excited to share this.
My little shop is in my garage which is attached to the house and thus dust collection is a big deal. The issue is that a lot of dust could potentially get into the house. So my goal this winter is build some dust collection measures to reduce the dust. Those of you who are familiar with 5S will know that the best way to reduce clutter (mess) is to contain it at the source. Thus a Shop Vac works well for small shops in that you can hook the hose right up to the machines and catch the dust there.
The problem is that the Shop Vac will have the filter clog very quickly and lose suction. That is where this Cyclone connection contains the dust before it ever gets to the Vacuum storage.
So I found this post on this site (Lumberjocks) from SteveMI for his “Easy Dust Separator”. Thank you SteveMI for your post. This was where I sourced most of my information to build this and I encourage all to visit his post for ideas to compliment mine.
Here are some images of how I did it:
To seal up the joints and holes I used Silicone Caulk and then weather stripping for those parts that move. The hardest part for me was myself was the intake pipe on the side. Really I just had to get over myself and put the pipe in, but I fretted over it for a week in how I was going to insert that pipe.
Some keys I learned:
1. Make sure you run the intake pipe past the center pipe for the Shop Vac.
2. Don’t over fill the bucket. I found that I can fill mine up to 3” to the top before it will start entering the Shop Vac.
3. Don’t worry about which side you put your intake pipe in. There was a statement on Steve’s site about atmospheric pressure and Northern Hemisphere and Southern Hemisphere. You are only moving the air in the bucket not the atmosphere so you don’t need to worry about which way you spin the air.
4. Finally, watch your container that you use. I found that if I put too much pressure on the suction it would actually implode the bucket. That is why I have the bucket inside the bucket. Just make sure that your container doesn’t collapse under the pressure.
These last pictures just show the dust I vacuumed and that it entered the bucket. Note the fine dust that is dropped in too. I didn’t have enough room to show the Shop Vac, but the filter was spotless and nothing was in the Shop Vac container.
I hope this helps those who are looking. Steve – again, thank you for your post.
