Seem to be having great results with rebuilt coils.

[James Laudano]

I have been rebuilding my own coils for the last few weeks now and am very happy with the results. The thought of having to buy poorly made coils every week or two was just to painful, so i decided it was time to learn to rebuild my own.

So far, I have rebuilt kanger, evod, vivi nova and a handful of other generic type heads. What I've learned recently, is that once you rebuild one type of head, you can rebuild them all, as long as they can be broken down and put back to together.

I have been experimenting with coils in the 1.4 to 3.0 ohm range and have found 2.0 ohms to work the best with most juices. What what im confused about is the fact that regardless of the ohms of the coil or juice used, I am able to adjust the volts or watts to their maximum output on my mvp 2 without any wicking, burning or dry hit issues.

I did initially have some flooding issues, but after switching to boiled peaches and cream cotton yarn, the flooding stopped. I use 65/35, 50/50 and 100% percent PG juices with no issues whatsoever. I just wouldn't thought that id end up with burnt hits or would have had to dial the voltage or wattage down when using different coils and different juice blends.

Am i doing something right here? or is something wrong with my mod? I keep expecting burnt or dry hits at 5 volts or 11 watts, but it never happens, even if I take a super long and hard drag. I use 32 gauge kanthal with 4, 5, or 6 wraps and am even using some 1.5 ohm twisted kanthal coils with great flavor. Thanks for any input.

Hi James. I have to confess that I've read your post several times and can't understand what the issue is? Your rebuilt coils are working well? Congratulations and enjoy!

Or am I missing something?

There's only a few things that can really go wrong with a rebuild. While the coil may seem like the most important part of the equation, it isn't....it's just the easiest to make a small mistake that can be overlooked.

Since you're using cotton as a wicking source, and cotton is excellent for wicking, you probably won't have a lot of dry hits. Unless you happen to over-stuff the wick, or strangle it with the coil....or if the coil isn't tight enough and it isn't touching the wick.

Coil placement usually isn't a huge deal either. Ideally, you want it to be near the air-hole, but if it's not...it's not going to break your vapor...unless it's shorting out on one of the walls of the deck.

I have a box of Kanger heads that I rebuild every now and again, but I find them to be fairly putzy to rebuild, and generally just easier to buy a new box when I find them on sale.

If you have some time, look into the Kayfun-style rebuildables. I've got a handfull of them, and they're fantastic. Easy to rebuild, quick, more space to deal with, etc. A good rebuildable is a bit more expensive, but unless you seriously break it, it'll last you for quite a while.

James,

Congratulations on your success rebuilding coils, I was big into rebuilding kanger coils back in the day with great success.

What you describe as far as being able to set your watts to maximum does not seem to be an effect of a hardware issue but is likely the juice your vaping allows good flavor at low or high wattage. There are juices out there that may not allow that. For instance a plain run of the mill tobacco mix may allow that but a sweet fruit or desert may not allow that. It all depends on the ingredients in the juice. Overly sweet juices may present a burnt taste at high wattage and a plane unflavored base would allow vaping at any wattage. The only difference in the unflavored vape would be the amount of heat you feel in the vapor.

As far as flooding it depends on how the coil is built and wicked as well as how well the tank seals. A reduction in flooding at high wattage could be due to the high temperature allowing the juice to vaporize faster but if you lower the wattage the flooding would likely come back. So for flooding issues I would always look to a hardware issue and not accept higher wattage as a work around or a quick fix.
