Where do I measure on the coil to see if it's 2.5", 3", or a 4" coil. Width of the circle or what? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Double the radius, halve that, then multiply by 2 again. You'll find this mysterious mathematical equation will always come out to the width of the circle. Every single time. Its how any real scientist measures circles n stuff.
