I gave a presentation about wood dust to the March meeting of the WA Fine Woodworking Association and it has been put up as a PDF on the FWWA website as a PDF.

For those that have followed my adventures in studying wood dust on this forum there's nothing new there but some of you may wish to show this to your woodworking club or mens shed.
On the same website there is a second article on dust by FWWA member Warren Murphy who spoke after me about his new dust control setup using an industrial strength Felder system. I came on board to help Warren with his system after he had committed to the Felder unit to help him improve his setup. In this article you can see what an almost unlimited budget applied to 170 m^2 of workshop looks like.
Warren's article is at http://www.fwwa.org.au/Art006_DustControl_c1.pdf
