Micro Coils to increase Vapor, flavor & TH

[Kyle&Ann]

Thanks so much Scrappy...I will give it a shot! I think I am having issues with the thickness of my wicks.

I am rebuilding Kanger protanks and Igo~W's. I am so looking forward to my first REO!

Hey all..

Really getting the hang of micro-coils. I did run into a strange issue today...

I recently got DARKZERO's jig tool (what a GREAT tool!)... so I eagerly got out my 28 ga Kanthal and wound a 11 wrap coil around the 1/16" mandrel. It metered out at 3.3 Ohms....ughh. So I did another and used only 8 wraps... 2.5 ohms... hummm.

My last coil I had I wound it around a drill bit that was a little bigger than 1/16" with something like 9 wraps and it metered out at 1.7 ohms...

So my question... being as the jig allowed me to make a 1/16" dia coil so easily... what would be increasing my ohms? I would think 28 ga with 8 wraps should be LOWER than my drill bit wound coil being as more wire is used in a smaller coil.

Is my thinking off here. Not that I mind the 2.5 ohm coil as its vaping like a champ... but would like to get back down below 2 ohms.

No problem buddy. I like making my wicks like this because I can repeat it easily, so when I have to figure out why a new coil doesn't work well I know for sure it's not my wick. That just leaves coil position as the culprit. Speaking of which, I get the best performance when the coil is a little higher instead of centered to the airhole.

Yeah those numbers are not right for that diameter, number of wraps, & wire guage. Something is wrong. Abnormally high resistance is usually a good indication on a bad connection, coil wires, atty to mod connection. What mod are you using, a Provari? I never owned a Provari, does a low battery give false readings?

With 28ga Kanthal the resistance should be a lot lower, around 1 ohm. When I measure a newly wrapped coil, especially a tight one, the resistance shown is high until I fire it so it glows even the first time. Have you tried checking the resistance after firing up the coil?

Ya thats what I thought as well...connection issue. I have had problems with my IGO-W catching the wire but not making a good connection when I use the thru holes.

I think I will wrap another tomorrow and use the TOP of the posts to get a better connection.

With you jig..I dont mind making coils now

I am using a provari with a fresh battery. I also metered it out on my multimeter and it agreed with the provari.

Oh yeah, this reminds me of the first thing I suggest to check when resistance is off.. that the screws on the posts are screwed down well.

Yep... I glowed the coil with a torch first. Installed, then fire it red 2 or 3 times and tweak the coils to ensure a tight coil. then I check my connections to make sure they arent loose.

Im thinking one of the leads isnt making a solid connection.

Yep, connection issue probably then.

Give this a try. Pull the wick/s out, stick the rod back in the coil, give it a little pull, then see if you can tighten the screw down a little more.

Glad we could help lighten your pocket and make your vapefu more powerful!

In the end, the vapefu is all that matters ... well that and vape mail. ;-)

Didn't you say you tested the coil on a multimeter? If so, and it read the same ohms, it's not a connection issue, something is dead wrong with your coil, if not, then test it and see what it reads on the multimeter

I have better results using the cotton yarn on protank builds. The peaches and cream is 4 wrapped strands. I just pull off 2 strands for the wick, and another 2 on top as a flavor wick.

Thanks for this information. Are you using this yarn ( 2 strands) with a micro coil?

 

[Jjshbetz11]

When I used protanks I used q-tips. They worked well.

Sup guys,

Had another failure of a build. My track record on the Reo is bad so far lol. I built a 9wrap nano Tinman Dragon Coil. The vapor shot out like a freaking champ on the test fire. Then I lined up my airhole in the path of the vapor and took a pull. Throat burn city! I mean, it didn't actually burn my throat or anything, but it felt like a massive throat hit and it was 0 nic juice. No flavor at all, just burnt flavor lol.

I should have known because when I dry burned the coil, it glowed instantly at the moment of fire. No heat up time whatsoever lol. I tried putting it on a cotton cloud instead and still same result. So nano Tinman wraps are a major no-go.

Back to the drawing board!

That means some of your wraps are glowing when they shouldnt. This is why i dont like the dragon build - the risk of hot legs is high.

How about just sticking to the basics? Im running a 2x6 parallel wrap with a Dibby crack. Awesome.

tried the same thing but micro coil tinman and not nano. Worked quite well for me. Ran a dual coil at .8 or so ohms and it worked hit nicely. threaded a bit of cotton through the coils and it fired right up. Seemed like slightly less vapor production than standard micros and the flavor seemed a bit strange like it was off slightly but still good. The tin man will definitely be something im gonnn have to experiment with again soon.






i always end up going back to the standard micro coils though, nothing quite seems to compare to a dual micro vape!

LOL...OK found part of my reason. I thought I bought 28 ga Kanthal. Welll the outside package says 28 ga, but the label on the spool says 32 ga.

So I wrapped another coil (6 wraps) with the 32 ga, and metered JUST the coil with my multi-meter and its 1.9 - 2.0 Ohms. So everything was fine.... operator error. thanks for the replys all....love this forum and the folks in it!
