No need to master. Wrapping the perfect micro coil is easier than wrapping tobacco, lol.
Just wrap normally with minimal gaps around a 2mm screw driver or any diameter you wish (usually 1.5 - 3.5mm), push it together, use a plier to hold the coils (recommended min 30 AWG and below), use blow torch to heat coil to red hot for around ten secs, then bingo, a perfect coil. run under tap water to cool it, dap to dry. all done within secs.
If u are using RDA, then the coil spacing might be loosen after mount, then just simply fire the coil using your mod to red hot, stop and use a tweezer to compress then let go, then re-fire and repeat process 3-4 times. Just use a normal steel tweezers will do, to squeeze immediately after firing stop. Not necessary to use ceramic ones.
Ceramic tweezers' (with ceramic tips) advantage is that you can fire and squeeze the coils at the same time without shorting it and melt the coils. But most people after using ceramic coils also end up using it like steel tweezers, LOL, which defeat the purpose, reason being, ceramic will break after you trigger-happy squeezing for long time under heat while firing, so LPPL, just use a freaking solid steel tweezer, unless you wish to appear 'Pro' while making Youtube vapings, LOL.
These will be the simplest, easiest, fastest, most effective way to do it by pros, rest don't waste time (totally no need to use complex coiling jig to tighten, align here n there, etc.).
If you should use a coiling jig, just get a simple one such as below will do. As in many things in life, Simplicity is the Ultimate Sophistication, same for Vaping. (Don't ask me where to get, just google, order and you will receive in less than two weeks, with free shipping, super cheap.)
