26 g 3mm 5.5 wraps slightly spaced - same to slightly larger coil length than top hole on coil case.
Thread wire through the top hole and out the bottom , poke a drill bit i use 2.5mm through the side hole through the coil and out the other end to hold coil in place.
Thread one wire through rubber grommet then bend away , then bend the other wire and insert metal 510 pin and press it in firmly.
Then cut off the excess , need to get as close to the coil as possible. Any wire sticking out even a small bit won't be able to screw coil in and even if you do high chance of a short.
Take out drill bet gently , you want it all to be straight - hole in side of casing - coil - hole in side of casing.
Check your resistance
Then I get kgd ( I peel off the outer layers on each side of the pad.) Take a width of 12 - 15mm ( this is whats worked for me) twist one end and thread through coil case and the coil and out the other side. It is tight going through but be gentle don't want the coil to get crooked.
Then I cut the wick ends about 2mm _ you can measure this as eyeballing it may not be accurate - although after measuring a few times I do eyeball it now.
Then i fluff the outside of the ends and gently tuck them into the sides.
The put some juice on the coil and on each side of the casing and check the resistance and for any shorts.
Screw it back on tank and wait a minute then vape.
