I did my first ever coil and took 4 attempts. Im doing 8 wraps of 28 gague kanthal hoping to get around 1.8 but ohms clocked in at 2.1 ohms. thats a bit higher than I thought. seems higher than the youtube tutorial said. Also the delay is like a good 2 seconds to heat up. Any suggestions on what I might be doing wrong here. Also another question when I put down the dripper for a while the first hit is super harsh but like no vaper comea out of my mouth thats weird right then I do like priming puffs and get the thing going and no more strong harsh throat hit. I dont get how the first hit produce no vaper and slams my throat. Weird l.

Need more info.. What are you trying to power that amp sucking coil with??????? What kind of atty? 28awg is a great wire for build at 1.8, but can be on the slow side if you have a low power device. Also sound like you have 1 wrap too many or REAL long legs on your coil. 29 or 30awg would be better above 1.5ohms but below 2.4. Could also be NOTHING wrong with the coil, but the wicking sucks.

use this Steam Engine | free vaping calculators to help getting whatever target ohm you want, it's pretty easy once you select your choices, the higher ohm build you make the slower it will heat up so you may want to try a 1.4 or 1.6 ohm next time to see how you like it

High OHMs doesn't cause slow heating.. That is caused by wire thicknes (amount of metal).
 
High resistance doesn't cause slow heating at all. Heating more wire mass (thickness or length) takes longer at a given power level.

OP, if you're on a mech bring your resistance down. I run 28 g at a max of 1.4 ohms per coil because ramp-up time is too long on anything higher. If you're using a regulated device crank it up a bit.

Either way check your wicking. That's likely the cause of your harsh hits and low vapor production. Wicking can be a PITA to learn. Took me 3 months (and a lot of wasted wire thinking that was the problem) to get it so I don't burn them anymore.

People focus too much on the coil itself. Building a coil is easy, there are precise instructions to follow. Follow them precisely and you'll have a perfect coil. Wicking is a guessing game.

like what kickflips said... more mass of wire = more rampup time for heat.

at 1.8 ohms with 28 gauge, the rampup time will be quite high. If I build anything with that high of an ohms rating, I tend to go up on the gauge (thinner wire). for 28 gauge, I like a .7 ohm build. I do have a 1.1 ohm build using 28 gauge in my kayfun, but it uses a kick, and it's cranked up all the way.

As far as the first hit problem, there's only one thing I can think of. Its possible that you have the excess wick around the coil that might be getting dry. I make sure no wick touches above half the coil if it's outside the coil. Only reasoning behind that, is if gravity takes it down, it will be an area of wick that's dryer(sp?) than the others. if you do have some, try pushing it away from the coil with a tiny flathead screwdriver.... just so it's not touching... probably 1/32" away. just my :2c:

Thanks for the tips. Im using an MVP3 set to around 9.5 to 10.5 and my wick is soaked around the back but alot dryer around the coil Which is set alot higher. Seemed like the right way but is what your saying I want the coil as low as I can get it and try to get cotton higher maybe over the post to wick better? Ill do another coil with one less wrap. Im also using a igo w. would you say that the igo w is on the small side or fairly standard size? Im also using japanese organic cotton.

Coil should be positioned where the air has to go through or around it to get to the drip tip... The wick need to contact the maximum amount of the coil possible, without obstructing the airflow or fluid flow or availability.... The wick will travel from the coil to the source of fluid to be wicked... Wick should never be between the air and the coil or the coil and the drip tip.
