Smjy doggystyle rta - is this right?

[tara81]

can someone please tell me if my coil is screwed on the dogystyle rta base properly? 10 wraps 28 g 1.8 ohm coil 2.5 diameter. It shows 1.99 ohm on the ohm meter and 1.89 ohm on my mod. I might have made too many wraps its hard to count they are so tiny.

Ive never made coils or used an rta before. I dont know if the wire is around the screw properly or if the coil is too close to the screws. Thanks if you can help!

If it helps at all, I found the doggy style incredibly difficult to build and I actually had to buy a second one to make it work. (The first deck vanished from the box, I think it was possessed.)

For your first coil mount you actually did really well. Honest. And, no, it doesn't matter if the leg touches the bottom of the deck and with the doggy that's pretty hard not to have happen with the way the posts screw down. You just want to trim your legs as short as possible.

Also, as long as your coil is somewhat within range, resistance may vary. Maybe your legs could be trimmed a little more, or they're longer than you calculated based on how the coil is raised up.. Etc. So, no HUGE deal. Check your deck for any stray snips of wire. Etc. If your coil is TOO high (on any RTA) your coil will read okay when you test fire or even wick it. But then read "atomizer short" as you put the cap (the bell of the RTA that encloses the coil). I've had that happen to me with the Ares one time, I just pushed the coil gently down and all was well.

I find velocity style decks the easiest style to build and wick, but everyone just has their own skill set. Etc.

Finally, if you are getting really frustrated, take a break (don't lose the deck! LOL). That is what I did with my doggy but with a lot of effort and experience building other stuff, the second doggy was a breeze.

Good luck,

Anna

This is how I position the coil on my Doggy (9-wrap SS316L, 2.5mm, 0.96Ω):

1st tip, ohm readers, unless you have a really well made expensive one are usually useless, and will lead to what youre going through, a circular pattern of misreadings and constant rebuilding. By all means build on it if you find that easy as a base, but get all your readings on the mod, thats what matters as the mod fires it, not the ohm meter

More of my rant against ohm meters in this post, because someone asked about ohm meters the other week: Never built a coil before

If youre worried abot the coil legs not being securely trapped you may be able to do what i do with my Lemo 2's, which have a lot less screw head by the look of the DoggyStyle to secure the legs, and wrap the wire around the screw a turn before screwing down.

Next tip: stick with it and watch the videos that relate to your tank(s) and take advice from others here, dont give up, everyones first experience in rebuilding is a learning curve. I started out rebuilding from day one of switching to vaping, no steeper curve than that...it will become easier, i promise

Also you are in no immediate danger of shorting anything, even the DoggyStyle has way more of a spacious deck between posts than a Lemo 2, found this photo showing how not to build a Lemo 2 lol. Coil too low, needs a lift....ive highlighted and arrowed the area of concern, this is far far closer to a short than you are

And this is similar to how i do the wire once round the screw trick....

[tara81]

I did it! I was so nervous but I did it. I dry burned and wicked them. I filled up two doggystyle sjmy clones and two vandy vape berserkers. Is it okay to store the tanks sideways in a case? Or do I have to keep them upright so the coil doesn't move ? The berserker looks so good with my tarot nano. I figured out I could dry burn at just 8 watts if I keep pulsing . Happy birthday to me! The doggystyle clone tastes better then the berserker so far, but I made the berserker higher ohms. I really need a magnifying glass to check my wraps, it's so tiny. I think my eyes are pretty strained from making sure the coil wasn't touching the post. I checked to make sure it wasn't touching before dry firing, during dry firing, and after wicking.


When should I recoil and change the wick? IS it bad that I like chain vaping, should I be concerned? I enjoy 5-8 second puffs, according to my revenger mini. I don't vape nicotine which is why I can chain vape for long periods.

It looks upside down. I built while watching this video - it shows you the process from coil wrapping to wicking:

Can anyone answer my questions:

If the coil legs touch the screw post on the top does it matter? No. "Leg length" is measured from the last point of contact. You'll want to make sure it doesn't touch the opposite post, but touching the post it comes off of is not a problem. In fact, the closer that "point of last contact" is to the coil itself, the better.

If the coil touches the screw does it matter? If the coil touches the screw, it will short to that point of the coil. Say it's touching in the middle; current will skip half the coil and jump straight to the middle, whereupon it will travel normally through the other half of the coil and see less resistance since it's bypassing part of the current path. This shouldn't cause an explosion or "violent battery failure" incident, however it might lead to "hot spots" and dry/burnt hits.

If the coil legs come out of the screw post will this cause a short circuit or explosion when fired? If the lead on the "negative" post (connected to the deck/base) sticks out past the post and touches the bell/"chamber," it's no problem. If the bell is electrically connected, it's got a negative charge and that post is negative anyway. If the lead on the "positive" post (insulated from the deck, connected to the center post) sticks out and touches the bell, there might be a short circuit if the bell is also touching the base. The base is electrically connected to the "negative" post; if the base is also touching the bell, and the bell is touching the positive lead, then you have a short circuit from the (negative) base, to the bell, to the (positive) lead, that bypasses the coil. This is bad. It (probably) won't blow up, but it won't work either and so you will still want to avoid this.[/B]

ThNk you, this is very informative. What is a bell?

Sometimes also called a chimney, or chamber. It's the part that covers over the coils so they don't get flooded with liquid. On the Doggy, when you unscrew the base from the tank, the bell is the metal part that's still attached inside the tank.

So i have no idea how to make this work. I thought this would be easy i tried the vandy vape berserker mini rta and my ohm meter keeps saying 0.02 ohms. Its wrong because its supposed to be 0.7 ohms clapton coil, I tightened it as much as i could and even tried the coil that came with it. I feel defeated. If only there was a vape shop near me or someone in my area that could show me. So sad. View attachment 750711 View attachment 750713

Trim the legs. Is the reading the same? Can you test on a regulated mod to make sure there isn't a problem with that ohm meter?

I got an ohm reader off fasttech for $10, and it's readings are significantly different from my mods. I never use that thing so it was a total waste of money

Also, I think it's basically a mechanical mod. I feel like the short protections on my mods are more reliable

This. Exactly this. Use the ohm reader as a base to screw your tank into for building on if you want to, but take the battery out and leave it out. Those things are terribly frustrating and led me to almost giving up on making my own coils.

Now I just build right on the mod (turned off, obviously).

 

[stols001]

My ohm's reader is mainly a stable base and it's not supremely way off most of the time. But for me, it's useful to build all the way up to a test vape or two. I really (if it's gonna happen) prefer to leak all over it than my nice mods and I have certainly done so a time or two. It just keeps going. LOL.

the doggy is very hard to build on, takes lots of patience, but if you get it right after many tries you will be happy If you want soemthing easy, buy an Innokin ares rta

Is it Kanthal? 1.9-ish ohms sounds about right for 10 wraps of 28g, if it's Kanthal (and that difference of .1 that you found between readings on different devices is not unexpected). I, too, would flip the coil over, though, so that the legs come off the bottom of the coil instead of off the topside. The legs will be shorter, that way, and the coil will heat more efficiently without the power loss in the extra-long legs. It might also allow you to drop the coil down a little closer to the airflow hole.

Maybe it's because I was already used to building my KFL's, but I didn't have any problems with the Doggystyle.

1 & 2) I'm not 100% sure what you mean because the coil leg must touch the screw posts and the screw.
The coil is wedged between the screw head and the screw post. What do you mean by screw post?

3)The coil must not touch the chimney (or another way of saying it - the bell housing that goes over the coil). That will definitely create a short circuit.

If you are using a regulated mod, then it will simply produce an error message (something like 'Atomiser short' or 'Check atomiser') and will not fire if the coil is shorted. Mechanical mods are dangerous if firing a shorted atomiser.

Don't give up You're further along than I am. I've been using the pre-installed coils and practicing wicking. When I finally get the right type of wire cutters then the hard part begins. I hope I have as much determination as you have .
That second to last Pic looks good.

 

[Janusz]

Yeah I got so frustrated I tried and tried for like 4 hours and gave up lol. Maybe tomorrow I'll try again! So strange the ohm reader doesnt read the berserker mini properly if that is the case. I was too scared to put it in my mod to check , what if I misfire instead of turning it off , as it takes 5 pushes to turn off my target mini. Im so paranoid , probably too paranoid to be doing this, but sadly I only taste like 2 flavors in my nautilis mini tank and I want better flavor sooo badly.

I vape for just 6 months...I bought my first RTA 5 months ago... currently I have a 8 different RTAs... I made and installed close to 100 coils in those RTAs (I like to experiment with different builds)... and ?!?!.............. I do not own ohm reader .... I always check resistance on my mod (Aspire Zelos or Geek Vape Aegis)...

Your Vaporeso Target Mini have build in:

• Over Temperature Protection
• Low Resistance Protection
• Short Circuit Protection
• Overcharge Protection

By checking your build on your mod your risk is probably not bigger than lightning strike on sunny day... and much, much smaller than your commute drive to and from work. If something go wrong with your build you will be informed by your mod screen ....usually on my it tells me -"no atomizer found".

Did you trimmed those long coil legs??? You should not check resistance with coil legs not trimmed... also check if connection pin on bottom of berserker is not loose (if it is use screwdriver to tighten it) or dirty.

Securing coil on doggy is not very easy... I was somewhat ridiculed when i expressed it on this forum a while ago...I wish it was as easy as on Siren 2 but with every attempt it will be easier... wicking is more difficult in very different way than coil building or mounting...in some way it is only possible to learn it by actually doing it (and it depends on our feel rather than exact science) Good wicking is learned fast but perfect one is more art than science... but doggy is very forgiving and much easier than many other RTAs in this regard... specially when wicked with rayon.

Be patient and persistent and you will be rewarded with great flavor and much cheaper vaping costs.

Tara - try it again. I found with my first time (doggy style RTA) it was a steep learning curve. But once I had got it working, it all clicked into place.

With your doggy: if you watch that video (turn the sound off ) at 4min30 sec - he takes you thru coil winding and then placing it on the deck. I built while doing what he did, pausing the vid, watching and doing the next step etc.

Your last pics of the doggy were pretty good - maybe just aim to have the coil a bit lower like in the pics @bwh79 posted.

The main thing is to secure the legs - cut off the legs, and with the jig in your coil - center it as much as you can.

Wicking wise - I found if you use a strip similar to the size in the video (about 7mm) and cut the tails as he does - the doggy is pretty forgiving. Its only ever leaked on me when an o-ring came off.

Don't worry about things shorting or blowing up - ive tested a coil on my mod and had one split - it just popped and I got an 'atomizer short' message. I've had legs come loose - got the same thing.

Good luck
