- do I want my coils as close to each other pushed towards the middle? As close as I can get without them touching? Or as close to the air holes as possible?
Depends on the RDA. Some work better with the coils pushed back. But usually, closer to the air holes is what you want.
- is there an optimal "power chart" that kind of gives you an idea of how much wattage to use for your specific ohm rating? My build on 2 fused claptons is .22 and I see alot of people suggest 55-65 watts , but mine is closer to 75-80 and is still by no means a hot vape.
Not really. For plain wire, twisted, and parallel builds, the heat flux calculation on
Steam Engine works great. Once you figure out what heat flux value works for you, the calculator will give you a pretty accurate recommendation on wattage.
Steam Engine does provide a heat flux per watt calculation for more complex builds in the
Wire Wizard section, but I've found it to be way off in figuring out what wattage to use. You are just going to have to figure out for yourself based on your own preferences.
- how often should you clean your coil ( and what's the best way ) and change your wick.
Depends on your own preferences (starting to sound familiar now?). And the specific juices you use can have a huge effect on coil and wick life. Some flavorings can gunk up your coils very quickly.
I rarely go more than two days with a wick, and most of the time I rewick after just one day. I take out the old wicks, and rinse everything thoroughly with tap water. Then I dry burn the coils until they start to glow, then put them under the tap – the rapid cooling breaks off any gunk. Rinse again for several seconds in case any of the coil gunk fell off into the deck, then rewick.
Most people go much longer between rewicking.
And I typically replace the coils after about a week, even though they still have a lot of life left. But I do have about a mile of wire total in various gauges and material to work with.
