So here is what I came up with, my first CFC. I used 16' of 5/8 OD soft copper(had 20 but kinked the two end, hence 16). I ran it in 1" ID EPWD hose from TSC. I used 3/4 x 1/2 x 1/2 T's(need to file out the pipe stop so you can run the 5/8 through it). Sweated on a 2 in coming out of the top into 1/2 x3/4 MIP female on one side and a 1/2x3/4 mip on the other. My first time I ever sweated a joint also. I wrapped it around my 14 stock pot. I think I might have only introduced a little kink at one part, hope it is not a bad one. I used a coper pipe hanger on the sides to hold it together. Took me like 2.5 hours. I had the coil already coil, tried feeding the hose on it, no way, had to un coil the pipe and then I lubed it with soap and push it through. For safety, I run my wall snake down the hose and pulled a stainless thread through, the tied that onto a notch I cut in the pipe. Here is the result, she is a monster!
