Using a CNC Router you can make a lot of stuff, but even more dust…
Of course i use a shopvac with a dust-bag inside, but in 1 or 2 projects its full.
Buying dust-bags all the time is pretty expensive, so what does the poor man do
Empty the dust-bag, and reuse it… Until? Yes the first dust-bag explosion…
I have seen the principle of dust collection using a cyclone principle on internet, and why not make one?
The principle of this system is to give the dust a rotating force, and let the inside clean air go to the shopvac.
First buy your self a cheap dustbin, and sell the lid as a star-wars robot helmet on ebay…
The first MDF ring has a groove to fit on top of the dustbin.
A smalle MDF ring and a sheet of aluminum form a cone that will guide the dust downwards.
To stay in to the MDF rings, just make 2 half ones now to secure the top side of the cone.
Cut the cone a few cm higher then the ring, and glue the half rings in place..
Make some cuts in the aluminum, and use your hammer to fold down the pieces..
Oke this will be the last MDF ring…
The top will get a 90degree elbow pieces, this is where the dust enters the cyclone.
Now the dust gets dizzy inside the cone, and falls down in the dust bin.
The straight pipe in the middle goes to the shopvac.
If all the dust is heavy enough to spin around the air in the middle should be clean.
The result, and the tryouts are to be seen in the video below…
Edit : A few weeks later…..
