Hi,
I've been lurking a while, and managed to sneak a reply in a week ago, but this is my first new thread. I've been working on a fiberglass version of the Bill Pentz cyclone, and got it set up today. I put together a quick and dirty web page about it here: http://lmills01.home.mchsi.com/gfce.htm, and attached a picture of the mostly finished unit.
