Check out
www.murphysmachines.com (I think) to see his processor - the plans cost about $100 but they look to be VERY detailed and it sounds like Murphy is really helpful. He also has plans for a nice wvo collection system "Super Sucker" I think is what its called. Also, another good site to explore is
www.journeytoforever.com.
Good luck, to you and me both.
