Hey y'all
Finally got into the rebuilding game with the OBS Crius V3, using Kanthal 26ga.
All attempts at 2.5mm diameter, dual coil.
1st attempt - after watching a few YouTube vids, I started out with a 10-wrap coil.
First, heated kanthal wire to remove tension (which I will avoid for future builds as I don't see the necessity); then proceed to wrap coil on 2.5mm screw driver (looking to build a Coilmaster in the future to use). Repeated for 2nd coil, and secured both to posts. Started wicking but stuffed the ends too deep in juice holes.
Result = atomizer low/short; slight burning taste when vape. Ohm = 0.1Ω
2nd attempt - changed to 6-wrap coil...again heated Kanthal wire and wicked too deep.
Result = heavy burning taste. Ohm = 0.3Ω
Final attempt - ditched the kanthal heating ritual but stayed with 6-wrap coils. After watching another YouTube video, I started to fire up the coils before i started wicking to make sure both coils fired simultaneously and evenly (learnt a trick about scraping across the coils with tweezers to ensure even heating). Also, after firing, used the tweezers to align coils better. Proceeded to wick (after coils were tested) so that cotton ends slightly visible in juice hole
Result = good vape at 0.3Ω
So after a few hours and a learning curve, I've managed to gain some good experience in the practicality of coil building and wicking.
A piece of advise, DO NOT always follow the YouTube videos to the T...one guy totally stuffed his juice holes (that didn't work for me).
What worked for me:
Also, I'm assuming that the burning taste was due to my wicking, where I stuffed the ends in the juice holes?
Also, what other builds could I experiment with?

A piece of advise, DO NOT always follow the YouTube videos to the T...one guy totally stuffed his juice holes (that didn't work for me).
What worked for me:
- no preheating of kanthal wire before wrapping;
- test coils for simultaneous, distributed firing (after securing to posts);
- after test firing, use tweezers to align coils better/bring coils closer together;
- wick so that a tiny piece is visible in juice holes.
