i guess it was going well. it was frustrating coiling the copper, but i hope it does a good job.



i used a piece of square aluminum for the support and then ran 2 different sized coils through it. i havent decided yet if i am just going to connect the two at the bottom or if i am going to extend them and make it 2 completely separate coils giving each a cold water feed or just make it all one big coil.

ideas?

if i make it all one piece should i have the cold go to the inner coil first or the outer

I think you'd be best to have to cold water in go to the bottom on the outer edge first. If you want to maximize heat transfer, you need to keep the temperature delta as high as possible. The outer edges should be cooler than the center due to heat lost through the walls of the kettle, and wort will be warmer at the top than the bottom since cold sinks and heat rises... though the effects of this my be negligible. The biggest thing I've found to speeding up cooling with an IC is to move it around in the wort... the effects of that will be much more noticable than whether you run the water in to the middle/top or outside/bottom.

It's been a while since I was up on all the metal interactions, but I'm thinking aluminum and copper aren't the best of friends.

I found this on Google but it's by no means any kind of scientific study.

Never Mix Metals Copper Aluminum Flashings

I'd think you'd also need to know if the makeup of wort had any influence for it to really matter.

My experience in all this was also from a roofing metals perspective. It might not apply here.

Yup, it's called the Galvanic Scale. If two metals are going to be in contact for a long period of time, you want them as close to each other on the Galvanic Scale as possible. Aluminum and Copper are pretty far apart so you'll see the Aluminum corrode and coat the copper.
