My wife stumbled on this and sent me the link. I had never thought of using ice to keep the tube from kinking while trying to coil a heat exchanger tube. +1 for the wife today.
Works good but the 1/2 can still get oval-ed. I settled for 3/8s for my Graham cuz I'm a slacker.

awesome. thanks for that! should be able to use some 3in tubing to create a 4in coil.
I entertained the idea of using water/ice when I wound my coils. Many raved about using table salt so that's what I used (not bashing water/ice cause I never tried it). I filled my coils up with table salt. Worked GREAT! No kinks at all. No noticeable flattening took place. I used 5/16" OD copper tubing which isn't all that large in diameter so I couldn't vouche for larger diameters.Only hiccup was dissolving the salt to clear the coil. Had to attach the copper tubing to a garden hose with NO leaks (required basic fittings). Turn on the water, let it sit and checked on it periodically. Once I walked out and say water streaming ... obviously it was clear. It took the better part of a day for this to happen.
My coils are double wound and fits inside 3" stainless pipe.
jesus, that's a nice piece of work...
