Started last year with 50 taps. Caught the fever in January and bought the spiles on ebay. We saved milk jugs for a month and only had about 20.
So of course after putting 20 taps in, and 30 spiles extra, I had to tap more. Needless to say SOLO cups fill up quick!!!

Heres a video of the evaporator. https://www.youtube.com/watch?v=sfAQ...o&feature=plcp

Had the blocks laying around, and found the pan at the junkyard. Its way to thick though.
