Hey, I had tried that link a week or so ago and it was no longer in use. I actually tracked down who ran the website and I think he sent me the design for the double 4 by 4 by 2' enclosure. I think this is the one that I am going to build, if anyone would like the designs, please email me and I will foward it to you. Also, if anyone has any other design plans they have used, let me know as I am not yet started and am still kinda looking. My email is [email protected]
