I am making a homemade still using a 5 gallon bucket for my coil. How long and how thick should the coil be? I have heard anywhere from 10 to 20 feet, I am just trying to keep it simple and spend as little money as possible here. If I go to Menards how much should this cost ? I went on there website and it looks like they only sell it in lengths on 60ft and that was $52.99. Thanks for any info before I go to the store.
