Hi, just for the plaisir to share, here is my cyclone dust collector I have built this summer for my new small shop. The cyclone was made from a 5×8 24 gauge galvanised sheet metal. Filters and the carton fiber recipient are from PSI. The dust collection system is drived by a 2 HP motor and a factory 12 inches impeller (blower from the old 1 stage dust collector). I used Bill Pentz’s site for measurement.

I’m not used to speak in english, but I hope these pictures will inspire other woodworkers who would like to build 2 stage dust collector himself.

Here is the 5×8 24 gauge galvanised sheet metal.

Cutting the peices.

The cylinder.

For the filters.

Spliter with foam between the 2 filters.

The bottom of filters.

Easy to disasemble.

In place.

I really love it and it runs!

I hope it will give some ideas…

That’s great, You’re quite the engineer. Great sheet metal work.

It seems to me that a cyclone would have somewhat better air throughput if the blower was upstream of the cyclone since pushing air is more efficient than pulling air. Two downsides to that idea are 1) leaks in the cyclone will blow dust and 2) everything runs through the impeller. However, these don’t seem like big drawbacks, except I suppose for that floor sweep you’ve got there.

How big a motor you running?

As long as the system is well sealed, I would imagine that pulling or pushing would be the same. That being said, GregD is right in that any leak in the dust container or connections to it will result in dust being pulled out of the cyclone b/c it is on the vacuum side.

Hi GregD,

As I wrote, the motor is a 2 HP. The blower is located on the top of the cyclone, but at the second floor (in the attic in reality) because I did’nt have enough room to put the motor right on the top. 10 inches separate the blower from the top of the cyclone and I made a cone inside the “neutral vane” inside the cylindre to make a smooth transltion between the bottom of the “neutral vane” and the pipe on top of the cyclone. A 16 inches metal pipe link the output of the blower and the input of the filter’s pipe and all is isolated (because we got -25 celcius degres in winter here).

All the cyclone was sealed with a polyurethane sealer that will never dry completely. with all metal screw and aluminium tape, I think it will last a time. It’s also easy to know if there is leak, we can heard it, I got experience from my first dust collection network in my basement and I took a time to seal the entire system with aluminium tape.

An interesting set up. Did you repaint your table saw to match the cabinets or is there a manufacturer that makes red tablesaws?
