Here is my first quad coil build. Measured out at .28 ohm.
4 coils, 1 ohm each. 26awg A1, 7 wraps around 5/64 drill bit.
I tightened up the bottom left coil after taking this pic.
Cotton wicks. Wicked thew the coils. I removed a lot of the cotton in the center after this pic. I vaped it for a bit and realized it was to much cotton suffocating the coils. I'll get a more recent pic. Clouds of vape and still good flavor.
