I am looking into cyclones and separators to reduce dust entering my RSDE-2 extractor. I would like to maintain the 4 inch pipe from machine to extractor and have looked at the super dust deputy which is a heart stopping 275 pounds. Then I cam across the Camvac black interceptor lid at a mere 21.00 and find I have an old plastic water butt that would be the right size and want to ask if this actually will work to separate out the heavy debris from the planer/thicknesser? I saw in a post from June 2009 that johnf says he has one of these, but being new to this forum I cannot work out how to contact him, if in fact I can do that, hence my posting to the general forum for assistance.
