For the CNC machines, we need a dust extractor.  If you’ve ever used one, you’d know how noisy they are.  We like a quiet, refined life in our Fablab, so we want to build a super silent cyclone-based dust extractor.  Something like this one at Instructables.com

To do this we need donations of two old vacuum cleaners (to be dismantled – you won’t get it back) and several hundred wine corks.  If have these or want to help with this build please let us know.
