One thing I would like to point out from that write up. I have read from other sources that stainless steel is very bad to use for this. It produces a highly toxic by-product in the water that is a known cancer causing element. I use steel rebar in mine and it works just fine. I'm not trying to pick apart the write up, just want everyone to be safe.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
