I'd love to see you're diagram Noble. This 10 CFM number that's come up in a couple of posts confuses me, and maybe this is where I'm making one of my calculation mistakes. To me it isn't keeping a flow of 10 CFM through the wet wash, it is more important to me to keep a velocity rate below 30 FPM regardless of CFM. Further, my testing has shown that it's advantageous to keep the velocity around 6500-8500 FPM through a venturi prior to a wet wash. I'd love to hear comparisons based on experience from anyone out there. BTW, the only cost effective recovery I could expect from my system would be lead from CRT's, and by my math it would take around 300,000 of them a year to pay off my machine(with pure lead @0.55/lb) within 4 years. Dare to dream, it's been fun think about it!
