When I first started making my own coils I found it uber frustrating.Sometimes the coil looked great but the resistance was all wrong,I'd try again to find the coil looked like complete crap but the resistance was where I wanted it.A few times I just wanted to throw it all out the window.
Over time and finding out about the steam engine site things just got better.I made my own coil jig from a few pieces of hardwood with a hole drilled into it to accept my nail mandrels held in by a set screw.
Now I make coils when needed and it takes maybe around 15 to 20 minutes from ripping out the old to making a new one and having it installed in my KF clones ready for filling.
It may be a chore to do BUT for me it's not an unlikeable one.
On a side note....I'm finding the switch to 2mg nicotine a lot more tolerable than the 4mg and can vape as much as I did before
Wrapping a piece of wire around something is the easy part. Mounting and wicking are the hard part. By the time i am done the coil looks like a knot.
