Gormit's GK Page

Just found some document on the internet that shows how  to DIY a dust vacuum (or dust separator). That encourage me to make one for myself.

First find the required material from garage...

1. Bathroom ceiling fan.
2. Costco wet towels tub.
3. Instant noodle cup
4. Case of syringe
5. Dryer vent pipe
6. Garden pipe

The wet towels tub use as a bin to hold the whole structure.
Open a hole on wet towels tub as a air intake
Cut the instant noodle cup to fit the curve of wet towels tub, which can cover the hole and use as a connector of intake pipe. Add a clapboard inside the cup to smooth the air flow.




Here is the core of the dust separator.
Double cyclones made from the syringe cases by open both ends.
The bottom of cyclones attach to a dust collecting jar.
On top of cyclones is a styrofoam cap. These two open black holes are air outlets from cyclone cylinders.
Styrofoam cap is cut to exactly match the size of wet towels tub open.


The jar cap can be open to dump the dust.

The wet towels tub cap also can press down the styrofoam cap to help keep airtight.

Additional Technical Information

I spend a lot of time on sending when doing GK prototype. Especially at the polish stage, the dust is so fine that I have to wear face mask to prevent inhale the dust. The dust also bother my family in the same house since the dust will fly everywhere, and may be bad for lungs and health.

Most the DIY dust vacuum machines I found on internet are for woodworking. They use the "cyclone" tech. to remove the wood dust. The power tools for woodworking will create a lot of debris in a short time. Using normal filter bag vacuum the filter will be clogged and lost suction. That's why the cyclone vacuum is more popular for the carpenters.
Also the most famous appliance "Dyson" vacuum machine using cyclone (does Dyson create the term?) too.

GK prototype will not generate as much dust as woodwork; but it will generate fine dust (like the one generated by sender in woodwork). Since prototype usually work in a room (or midnight), a quiet machine is a must. So I choose a ceiling fan instead of real vacuum machine, because it is much quiet then a vacuum machine.
