I purchased a 100 ft roll of 1/2" stainless tubing because I couldn't pass up the price. I'm getting ready to tackle turning it into 2 50 ft herms coils. Does anyone have any experience bending one for themselves? I don't want kinks and I am a bit retentive so I'd like it to look great. It's going into a brand new polished keggle. I was thinking of using a 10 or 12 inch pipe As a form in hopes of having a 13 or 14 inch diameter coil. Any thoughts?
