A while back I posted a home made dust collector I found on ebay.

After setting it up, I found that the separator wasn’t that efficient. It basically sucked the dust in and smacked against a plywood wall and fell into a waste basket. I had just bought two new filter bags and didn’t want to plug them up tons of dust.

So, I looked into a buying a cyclone but they seemed too expensive so I thought of a way to build my own. I used 26 gauge steel sheet from Home depot. I spent around $100 when it was all said and done. All the gaps are sealed with construction adhesive and gutter seal.

My biggest challenge was to create a spiral that a 4 inch pipe could stick into without leaking air. Then, it dawned on me, if I just cut a spiral with a bandsaw through some particle board, then I could just shove the steel up the slot and that would bend the sheet into shape. I added some pictures so you can see the band saw cut. It was a very effective way to create a “coil” or “spiral”. I couldn’t figure out how to make a cone so I just made a pyramid out of wood. The lid is held down tight on the trash can with some bungee cords.

In the end, this thing really works!!!

With the money you saved by building your own systen you can be very satisfied! Good cyclone systems are not cheap.
Nice job!

I like home made dust collectors. They often work better than the expensive high priced commercial ones. I’ve made several and they all work great. Good luck with yours, it looks like it will work fine.

I appreciate your ingenuity.

You may want to take a look at the Bill Pentz website, he’s got some very interesting design notes.

I think you may run into trouble in that your funnel isn’t turbinating the air, due to the square sides.

Have your say...
