My Mini Cyclone

I had to replace my shop vac. Sanding dust destroyed the bearings in the old one way to early. So for this one I wanted to keep as much dust away from the vac as possible. I started with Bill Pentz’s cyclone calculator and only planned to build the cone, similar to the Dust Deputy.

I made it out of 26 gauge sheet metal, 2 1/2” hose connection in and out with a 3” drum connection. Sealed the connection PVC to sheet metal with hot glue. I put it on a 5 gallon steel bucket with a lid and seal ring.

On my first test I vacuumed up a full 5 gallons of saw dust from my planer, only had a table spoon of dust in the shop vac.

Thanks for looking!!

I’ll have to do some looking at the bill pentz site. The dust deputy looks like a good solution but I just have such a hard time understanding how an injection molded piece of plastic could cost 50+ dollars. I’m surprised that there isn’t a Chinese knockoff in the $10 range but I haven’t found it yet.

Good job on the build, how much time and money do you think you spent?

grantd,

I used a piece of 26 gauge 6” duct that I had on hand, flattened out and drew the shape, I had the 2” PVC left from a plumbing job on my new kitchen. I used copper rivets to close the seam. Time, it took me about 3 hours to make the cyclone. But all the parts were from left over around the shop.

Nice job; very gratifying to see someone be creative/inventive and solve a problem without just buying the solution. Thanks for posting.

Great build- I’ve been trying to come up with a similar design myself

Have you tried doing some sanding with a 100+ grit ROS or similar yet? That is most of my shop vac usage – my DC is hooked up to the machines (tablesaw, router, planer). I am interested on what makes it past the cyclone from that type of work.

Thanks

Looks like you can get your system through the shop nicely. Have cyclone will travel!
