I'm seriously considering building my own, I have a few AK pages bookmarked for reference. I am handy enough to build it, just a little research to get moving on my behalf. #1, Is their a homebrew recipe for the solution, and what is it? #2, How often is the solution changed, or can it be filtered for reuse? #3, It seems the slower RPM's is better, correct? Would less than 3 rpm, work? #4, Once cleaned, is their a preferred method to dry the albums, fans/air dry/microfiber towels? #5, Will a somewhat "nasty dirty" album be resurrected for play after 1 cleaning, or will multiple cleaning be required? (The kinds with lots of grime from being mishandled). #6, What was your biggest headache in building the dang thing? #7, Probably haven't covered everything, feel free to contribute here. #8, Is a 6L tank sufficient? #9, Was it worth the effort? I built a vacuum based cleaner, it's fine, but always looking for "better" Thanks for your input, as I move ahead, I'll document my build, and post my results later.
