Come on you folks!

No one here cares about who has what, We would really like to see your gear and what you mount your coils on!

All are welcome here and we are all friends!

Lets see your stuff!!

vape On My Friends!

LOL. My trusty VAMO runs the monster at 1.29Ω with the appropriate tip for airflow.

(Only stick variable that'll go that low reliably for under 30$!)

That is a nice little forrest you got goin' there crg.

Good luck.

:)

Nice! I can bug you for advice when my KFL+ V2 gets here Friday! Think my SID should be too.

You guys are gonna drive me into the dirt this Halloween. LOL I'm gonna have to round up all the Kay's that have been piling up in the corners and crevices I never seem to get to. It's bad enough the dripper collection grows daily. I guess we'll have to start up the Kayfun t.m.c. Discussion! thread after all before we have a gory overflow.

Good luck.

First try - 8/7 wrap, 30g kanthal, 5/64, 2.0 Ω. Need some practice, I notice the ends aren't perfect, but for the first time usage, I am psyched! I have been hand winding on a 16g needle so this is a different feel for me, but easier to get the tension just right. I also switched to a Lightning Vapes base from an EVOD clone base; the 5/64 fits perfectly in the LV base where it did not in the EVOD base. Humm, now what else can I rebuild around here...

That looks pretty micro to me. Looks like an EVOD base. LV's cores for the PT are ~1.8mm. Shame we can't get them bigger. The upper cylinder of the dual coil cores is 3mm so the slot could be wider but in fact it's also only 1.8mm. Not ideal for XC-132 but cotton users and possibly users of the silica 3M XS-132 could benefit.

Curious what the diameter of your winder is. Hopefully cig will pipe in. I don't have time to locate mine and mic it. What happens when you have overlapping multiple appointments.

Now that you're seeing the better advantage of leverage just a tad more tension should get you adhesion end-to-end. When you get there things just blossom from that little coil.

Gotta run, good luck.

Congrats clnire! Looks like a good wind. Nice tight compression tension. Now to dial in the set. Both end turns appear to be unwound a bit from inserting the insulator and pos pin. Those end turns will not have the same wick compression as the rest and will get hotter quicker resulting in a burny taste. To keep this from happening make sure to hold BOTH legs when setting the insulator and pos pin. This way the legs won't get forced towards the mandrel. Almost there!

Thanks cig! That's what I saw too. I wrapped 2 more and managed to keep the end wraps tighter each time. With practice I will be building pristine coils in no time!

Pristine coils, a vapors' dream. We try to achieve them on every build. Doesn't always happen but when it does the effect is remarkable. Higher wattage capabilities come with perfect winds and sets. Can mean the diff between burny hits at 7watts or at 11watts. When they go down right and you belt out a 4ft. long opaque white cloud you'll think your name has been changed to "holy s<>t, what kind of clearo is that"? Lol

Have fun clnire,

:)cig

Ok re-reviewed your build and I think I see why your end turns opened up on you. See in the pic how the pos leg wraps almost all the way under the coil then makes a sharp bend before entering the insulator? That's why your end turn opened up; over wound legs. When you are finished winding your coil the pos and neg legs should be parallel in their relaxed position; or maybe just very slightly under wound. I'm suspecting that they were overwound because the bend indicates that the leg was pulled/tensioned to it's current termination point from somewhere else. This will cause the leg to bend as in the pic and open your end turn diameter. Optimally you want the leg to exit right off the side of the coil and head straight down to the insulator from there with no bend. I suspect the neg leg looks similar.

Some folks like to use a more advanced termination arrangement called an "x" or "y" configuration. There may be advantages but I'm just too lisDexic to use it. Lol

I see what you are saying cig. My 3rd wind was much better (sorry should have taken a pic) but one of my fave juices was just not giving me the flavor it used to even with clean, dey burn, through rinse/dry and rewick with KGD. I put that 3rd coil on the Evod (with KGD) with the fave juice and I am back in flavor heaven!

I am going to keep working on it. I realized I was turning the wire, not the tool Duh! Much easier now.

Mac, clnire's winder has an .067 on one end and 5/64" (actually .0765) on the other. Hope this helps. Honestly have forgotten what I sent you. Maybe .067 on one end and 4-40 screw on the other?

The 10pack of .070 bits I bought as of late all measure .067 but I had a couple of .069's lying around. You may have gotten one of those in your winder. Both work quite well with RXW Nextel XC-132.

It's def 4-40 on one side which is a good dimension for winding. Dunno the other. I deburred the screw slightly with some common steel wool and some quad but not enough to get it slippery. S'good. Haven't run XC through 'cause it is about 5/64" as 132 really doesn't perform as well there. And I never ran it on a spaced wind as a t.m.c. always outperformed both a torched contact or tight m.c. on everything from a 16th to 1.8mm. So that pretty much clinched it. However, that diameter might be excellent for XS-132 if I can get more to get around to it.

Thanks for the heads up.

Good luck.

Nice to see you making progress. Thought I'd throw in a minute.

Basic rule of thumb I follow these days (after going back and forth several times) which I'll describe here. When I begin assembly (grommet insert) while making sure bit is firmly at bottom of slot with index and middle finger, coil inverted, I immediately set the neg at, let's say, the 11 O'clock position bend the lead up towards to top of the assembly then use the grommet to trap it in that precise spot pushing the grommet in only half-way or so.

If you do this the rest of the build kind of follows along naturally because you've now set an anchor, a reference point.

The neg lead should be perpendicular to and exiting the bit in the direction of exit from the coil. It should be tight to the bit. If not add slight gentle pressure to the lead until it is, then again bend the lead up towards the top of the cup. Finish inserting the grommet as you hold the lead firmly with your thumb against the side of the assembly. This will positively avoid any push up of the end turn.

Follow suit to set the positive at the 5 O'clock position and just hold that in place with a finger on the edge of the grommet. Proceed to insert the pin again about half-way.

Now is the time to inspect the end turns from above and balance the tension between the leads if need be. Also to ensure that both leads are perpendicular to the bit and terminated in the direction of exit (not at an off angle sideways or down). If need be re-establish the 11 and 5 O'clock positions and re-balance the tension.


385749d1414721845-protank-microcoil-discussion-img_1153a.jpg



If the symmetry is good use a fine point tweezer to make a sharp-L bend to the positive lead exactly at the point of exit from the grommet. This 90-degree bend will serve as a strong deterrent to positive lead slip upwards when you complete the pin insertion. Once the lead is trimmed it also deters it from slipping up and out as a hanger. Ensure the pos lead is tight to the bit and complete the pin insertion. One variation is to snip the positive right then while exposed. Then complete pushing in. This can make for a cleaner termination. You may still retention the positive using the short lead above the grommet if need be.

Perform a final check of the end turns and overall symmetry ensuring there is no skew. If all is in order, you're done and can snip off.

I'll just reemphasize that terminating in the direction of turn exit is the best way.to ensure reliability of your build. Not saying you'll nail it every time but try to make it the objective. An inward set or outward set vertically has a far greater chance of skewing the coil later as tension forces are reapplied with tank refills. It's already tight and short. It may work flawlessly initially but such sets have a higher failure rate particularly with silicone grommets.

My current strategy is taught and symmetrical. But I avoid tight leads as problematical in their own right.

There you have it. Good luck C.

:)

Always had the best luck with tmc coils with xc-132 as well. .067 seems to be a good size for it. Did try a couple of spaced winds and a couple of "micro-spaced" (winds almost touching) on .067 for dirty nets. Worked ok but still looking for someone to trade some 3mm for the 2mm slim rxw I have on hand. Kinda hoping the 3mm will have greater juice capacity to keep up with my vaping style.

Night,

on the show your stuff theme,
So this is missing two trays of steeping juices , the 3 sizes of kenthal, and a few other assorted parts...
but its mostly protanks and clones, an emow or two might even spot a evod in there
Do you think I bought too much in the month I've been back to vapeing? I grabbed what was close and made a loose group photo.. lol.
I do really mean to make this stick.. I really need a good mod that I can diy.. I can solder / etch boards etc but the $100 plus cost does not seem right for whats likely actually there in all but the best.
Now as for that perfect coil... I'm so close. have not built a jig but have added the tension and think I'm almost there..
Gonna put up that sexy 10/9 centerfold pic real soon.
loving this thread.. Thanks guys and gals
