This project was inspired by Jeff (jcoulam) who posted the first cyclone dust collector a couple days ago. I do not want to take away any credit from Jeff for his brilliant design and willingness to share his work. As I was building this dust collector, I took a few pictures to document my progress. I will be glad to write a blog later and share with you how I built this project.

The most difficult part was the cone. I tried Jeff’s suggestion and just couldn’t twist the metal sheet enough to form a decent cone. I managed to get a small cut in my hand in the process. Ouch! So I decided to learn from my wife who uses paper pattern in making her clothes. I cut a paper pattern that can form a cone and then traced the pattern onto the metal sheet. I then bent a lip on each edge of the sheet so they can hook on each other. Instead of using sealant, I decided to solder the seam.

The intake tube was cut exactly as Jeff described and I taped a piece of sandpaper to the cone so I can sand the tube to the same contour. I then use 2-part epoxy to glue the tube to the cone. I use a dust collector adaptor to anchor the collector to the 5-gal bucket. Other than the adaptor I use the same materials as Jeff used. Here are a few pictures of the construction.

The final product works extremely well and exactly as Jeff described. Once again, I want to thank Jeff for a wonderful idea. It took me a couple days of off time and about $20 to build this collector. Thanks for looking.

PS. In order to make this whole system mobile this is my latest upgrade to this system.

I have got to make me one of those things. They look absolutely perfect. The one 4 inch one I have works like a charm but the 2 incher I have on my shop vac seems to plug up all the time and the bucket collapses. I mean the walls of the bucket will squish right in and touch each other. Thanks for showing how it’s made again.

It looks great, and glad to hear it is working well for you. Do you find it a bit tippy because of the tallness of the cyclone vs what the Dust Deputy looks like?

PS Does someone have the original thread that started this saved for a link?

arw01, you are right about the smallness of the Dust Deputy which measured about 14” tall and about 6” dia at the top. My diy collector overall height is about 28” and weighs about 5 lbs. Surprisingly it sits pretty solid on the oversize 5 gal bucket that I used. I am thinking putting both the shop vac and the cyclone on the same platform with casters so they can be moved together.

Hummmmmm——I wonder how a larger version with a 2 HP motor would work. I really need a cyclone in my shop.

Hi Simon, you did a great Job and I would like to do something same. I think that for effectiveness, there is a need for a certain proportion between the length of the pipe which goes into the cone and the length of the cone itself what about the diameter proportion between the diameter of the pipe and the top side of the cone, what about the proportion between the top side of the cone and to bottom side of the cone. I afraid to do other diameters and have a cyclone which is less effective. thanks a lot

Hi Eli,
I think you are absolutely right about the proportions of all those you mentioned. To me the most critical part was how far the outlet tube goes into the cone in relation to the position of the inlet tube. If the outlet tube extends too far down into the cone, it will pick up the dust and chips before they fall to the bucket. Same is true if it is too close to the inlet tube inside the cone. My outlet tube extends about 6 1/2” into the cone so it passes the inlet tube by about 2 1/2”. I have not permanently sealed the top yet so I can take the top assembly out and reduce the length if I need to but so far it is working extremely well.

Here are some dimension of Oneida’s Dust Deputy. I don’t know how well you can see in the picture about the outlet tube inside the cone.

Here is what I noticed in the Dust Deputy dimension:
1. The top diameter is about 3 times (6”) of the 2” outlet tube.
2. The top of the inlet tube is about 1” from the top.
3. The end of the outlet tube inside the cone passes the inlet tube by about 2 to 2 1/2”
4. The bottom diameter is about 3.5”

Great Job!! You have some great assembly tricks, I like the sanding jig. I really like your pictures and your blog. I really hope to see more of these, they are so simple to make and they work so well.

Jeff,
Thanks for the compliment. Coming from the original designer of this homemade tool means a lot to me!

Looks great, just one question, where you attach shopvac would seem to be a weak spot. What do you do to give it a little strength? Thanks for sharing.

Bill,
Thanks for the comment. I think the weakest spot is where the inlet tube goes into the cone. The epoxy has very little surface to grab on and the sheet metal is thin. The outlet tube connected to the shopvac is in fact quite strong as the PVC is glued on to the 3/4” plywood and the PVC elbow also provides additional stability to keep the outlet pipe in place.
