Youtube videos are the way I learned. When you see it broken down you will have a better understanding. I believe the V5 is 1.5 ohm minimum.
Guage of kanthal, inner diameter of coil and numver of wraps will help us to try to figure it out.
Now. I dont believe you are getting .8 on that single coil. It should read higher unless there is a short. The actual coil installed isn't bad. It just needs to be tightened up by applying power then cutting power and pinching them with pliers or tweezers.
Are you trying to do a dual coil? If so then yes you would be getting .8 ohms. Remember dual coils cut the resistance in half.
EDIT: Actually if that is more of a "nano coil" (wrapped on a syringe needle or something similar) . Then, yes. It may be .8 ohms. But it is hard to tell from the pics.
