I am looking to build a chiller, either a CFC or an IC to handle cooling wort in my newly built 15.5 gallon keggle. I am leaning toward something like Jamil's with the whirlpool return, which gets the wort circulating against the IC, but I wanted to see what everyone else built and make a final decision. I have read a ton of posts and there are so many different ways to build one, I wanted to get a thread going with them all in one place for other folks like myself looking to DIY. I know that there are a million different ways to build one so show 'em off!
50' 1/2" Bobby_M style. No connector on the outlet as the 1 I bought must have been aluminum alloy instead of brass and wouldn't solder. I just slide a 10 gallon cooler next to the pot to catch the discharge. Total cost was right at $55 (I had solder and torch already).
