Just made an IC from 50 feet of 3/8 copper tubing.
For fittings, I went the easy route and just slid some 5/16 vinyl tubing over the copper and ring clamped it tight.
I just did a big test session to measure time to boil, boil off, and then time to pitch temp using the IC.
Well I must say, the IC works better than I expected. It took my water from 212 down to 90 in under 6 minutes. I almost couldn't belied my eyes. Tap water was at 80.
In order to increase water flow between the coils, I plaited some welding wire on two sides. This helped make the chiller more rigid and also opened up little gaps between each coil. The wire I presume is coated in copper (as most welding wire is I think), and the core I'm not so sure about.
Anyway, after chilling I poured the water back into a fermenter so that I could measure volume, and the water had taken on a slight yellowish tinge. Is this normal? Is this welding wire safe enough to throw into boiling wort?
