Hey i'm building my wort chiller, hopefully today. I wanted to know how much space to allow between the chiller and the pot. I'm using a 40 qt pot which measures 14" in dia, while a clay pipe from the garden i wanted to use measures 8" dia. Is 3 inches too much or will I be fine? I also have to keep in mind that this is my parent's pot. When I move back to Washington, I'll probably buy a 32qt b/c its cheaper.

what do you think

8 should be good. Just make sure all the coils are submerged when you're at your final boil volume/level.

ok so i finished shaping everything. I saw on someone's blog they soldered the grooves together so it holds as one. I just spend about 30 minutes soldering and resoldering only to see my solder fall out after tension is let off the coils. How else can I weld my tubing together in a food-safe way?

I used copper wire (from regular romex electrical wiring) to bind the coils together. Seems pretty sturdy ...

You're probably not getting the copper clean enough. The parts that you want soldered together have to be spotless and shiny which you achieve with 220 sandpaper. Apply flux, heat, solder.

Agreed... Use some sandpaper to prep the copper.

Be sure to post some pics of your build. Brew pr0n is always appreciated by us all.

How do you apply flux? Is that a liquid or something? I just heat and solder. Also, I'm using silver solder b/c its lead free. Right now I have zip ties holding the coils together while I wait to solder

Flux is a paste that is applied to prevent the oxidation of the metals when they are heated to high temperatures. You can get a small can of flux at your local plumbing supply store, hardware store or Home Depot for a few bucks. You "paint" the joint that you want to solder prior to applying the flame with a small brush that you can purchase when you buy the flux.
