Thanks to all you bloody guys on here I'm just going to have to try AGs or partials sometime, even if I am still new to all this. The extra control and participation sounds like just the sort of thing for me to kill half a day or so on.
My question is where the hell do I get copper tubing at a decent price from, without having any family plumbers? I went to bunnings today and the copper was well over $200 for an 18m coil, and i think that was 1/4'' tubing but it wasn't labelled very clearly (they had 1/4'' and 3/4'', the 3/4'' was over $400 per coil, $22/m, but no 1/2'' that i could see). This is in perth, I have read other posts saying they could get 18m for just over $100, which is a much more manageable figure.
I think for the manifold I might be ok since there is some hope without copper (ie steel mesh) but for the cooler I am SOL without a pile of the copper tubing. How appropriate would it be to have two boils in say 15/20L pots and try the ice filled sink approach to cooling? I can't image this working for a full 23L wort, but could I expect the two pots to cool sufficiently quickly to avoid chill haze and oxidation?
