I use a straight needle probe, the little blue
rba screwdriver, and 2 different 2mm
threaded rods for 1mm ID, 1.5mm ID, and 2mm ID's approx/respectively for small coil builds. The two different rods, one with a coarser thread for 28g and heavier.
Wrap, align legs and pull tension with a basic set of pliers.
I get consistent builds for both drippers and replaceable clearo heads.
I'd get a coiling gizmo, but after doing it enough times you find that you become pretty efficient doing it by hand.
Cheers.
