I'm sorry should of clarified, it's 2.5, after attaching to nr wire about 2". Not bending back on itself, have no idea how to make a dual coil,lol The spool of r wire says 34gauge kanthal so maybe its mislabeled? But yeah I'm only getting 2 coils with 2" 34awg kanthal a-1 on the triple wick method. Ohming out to 2.8, I run it at 5.3voltls which is vaping great but was thinking i should have more coils around the wick.
Your measurement is off. You need to measure only the Kanthal resistant wire. Bust out your measurement tape and measure exactly 1 inch of kanthal wire and cut it. 1inch will get you 3 to 4 coils. Done right and if my calculations are right it will bring you to 1.8-1.9 ohms. perfect to vape.
