Dust is a menace and I wear a mask when I am cutting and cleaning up after.
If I had had enough space I would have built the same setup as built by philipw; see his post on his setup:viewtopic.php?f=8&t=703&p=1735&hilit=oneida#p1735
However as I don't very much space in my garage so I decided what ever I used must be installed under my table; (the Oneida cyclone units would have been too tall to fit under the table), so I went for the Thein Cyclone Dust Separator system;http://www.cgallery.com/jpthien/cy.htm
I have built a 3 stage Thein Cyclone system to collect my dust; it consists of a Vacuum Cleaner as stage 1 and then 2 connected buckets with Thein Cyclone Dust separators installed to catch the dust, the same type of system philipw built using Oneida cyclones units. The bucket closest to the router picks up almost all of the dust! Then what little dust that is not trapped in the first bucket is sucked into the second bucket where almost all of it is trapped. Finally what the vacuum cleaner it self gets at the end of the process is so small that I don’t think I will ever have to buy another filter.
I still need to perfect the design of my dust shoe to catch all the dust at the tool head however I am working on it.
Currently I am working on the boom section of the vacuum pipes to reach over the table to follow the router as it travels the full area of my 4ft X 8ft table. When it is finished I will take pics and maybe a short video.
