Dust extraction


Our first solution to our dust extraction problem.  Worked a treat, not great having to accelerate the mass around all the time though.

Next step was a simple shop vac cyclone.  about $30-40 on ebay.

Some corrugated tubing, plumbing fittings and a bucket.

Note:  Don't use hard corrugated tubing.  This is the stuff used for irrigation and has a stiff wall.  The hose howled lack a banshee with air flowing through it.  The turbulence from the corrugations must have lined up with the resonance of the wall or something.  The noise was loaded than the cheap router running at 30,000 RPM.

We ended up buying proper soft walled vacuum hose from a woodworking shop that did the trick.

First crash. 

First useful parts.
