I really suggest spending some time looking at this site.

http://billpentz.com/woodworking/cyclone/index.cfm

It has tons and tons of great information, least of which are the health hazards associated with dust from wood working. I build a similar cyclone as shown on the site, except that it's for my metal shop instead of wood.

Hope this helps. Paul.
