A couple of coils I've done on my Igo-L:
My first attempt. Using a simple wrap with 32 gauge kanthal and 2mm wick:
That worked well....then I read about micro coils and made this one, about 8 wraps around the screwdriver included with my Igo, wicked with cotton. The resistance was high, but it still vaped nice on my SVD around 5.5 volts.

I since scrapped that one due to a great suggestion and built a micro coil with 30 gauge kanthal, 10 wraps around a 1/16" drill bit, and then wicked with cotton. Sorry, no photos on that one right now. I can try later when I clean it out. Right now it's nicely gooed up with Gorilla Juice. <Yum>
