noob ?s low ohms concerns

[AttyPops]

So basically...

You guys want to max out the amp draw, thus the watts to the coil, by using the minimal ohms for your particular setups...while maintaining "all mechanical" specs.

The # of wraps of coil and coil size would be a factor, as well as the closeness of the individual loops and the wicking capability of the wick. All in addition to the gauge of the coil wire/ribbon.

Still sounds a lot like the DCC argument to me...

Yeah the coil, how it's wrapped, and wick ability is all part of it. The thing is it gives crazy good flavor/vapor/th that I have never been able to duplicate on a VV device. Without going out and building some monstrosity by hand I think it will be a long time before one pops up that can do it.

I prefer VV/VW for premade burners like cartomizers, clearomizer, standard atomizers, etc. I don't use those personally anymore but variable devices definitely were better for them.

Well, sort of. For some, perhaps. My #1 priority is durability and as a function of that, mechanical simplicity. Rather than shoot for maximum lowest resistance and maximum amperage/wattage, SLR on a mechanical provides me a way to get what I feel is a superior vaping experience on an unregulated, unboosted battery device due to electrical principals thoroughly discussed earlier. This means taking the limit of the battery into consideration first, which without mechanical voltage drop taken into consideration, is generally between 4.2volts and 3.6-3.8. A fairly narrow range.

I wrap my wicks to offer the flattest perceivable performance across that range. As a benefit, but not necessarily the goal, this means a rather low impedance, high wattage coil with a relatively long run of thick wire around much "fatter" wicks than one will usually find in a VV regulated device. This in turn, provided improved air flow is also taken into consideration, a much more "productive" vape.

 

[AttyPops]

OK so...NOW we're getting into it. Fat wicks and long runs of wire....

That's more the thermodynamics of it. (yeah, I know the ohms are there too...)

Not bad for $35.00 Catt. lol.

100 watts. A/C mains powered. Could probably rig a battery supply instead if done properly....

Meh. Just get one of these

[SwaK]

Man, this was one of those great reads. Thanks again everyone for the great discussion.

 

[Oktyabr]

I wanted to "prep" for any unforeseen event... FDA crack down, zombie apocalypse, or just a week long camping trip into the mountains. This caused me to hunt out the most reliable vaping device I could find and I don't think it gets any more reliable than a true mech and some extra batteries.

IF a VV/VW device could offer the same sort of vaping experience I would have bought a mech anyway for the reasons I listed. That said, as discussed elsewhere, I truly do perceive a much greater vapor production with a mech plus a properly utilized SLR capable attachment. I'd be happy to experiment further with VV/VW devices towards this same sort of vaping experience but so far I've come up empty handed. That's NOT to say that a VV/VW device can't supply an incredible vaping experience! They certainly DO. But yeah, I have to agree with what others have said... SLR on a mech is a whole different level of vaping... and may not be for everyone.

This is it exactly... I looked to Mech & RBA originally to avoid the FDA Vapocalypse ...

Discovering SLR was a rediculously nice bonus.

Discovering SLR was a rediculously nice bonus.

Yup! It wasn't even my goal when I started out researching mechs

 

[D4rk50ul]

I started on proprietary devices and moved to mechs mods as vv wasn't around back then. I will admit I used VV devices mainly other than my Reo w/HH357 for a long time until I got into rebuildables. Now all my VV stuff is collecting dust as I'm constantly finding new ways and materials to make my RBAs work better and better.

I do admit genesis atties have their flaws, as does any device. I personally prefer my Reo with a BF RDA on it for that dripping performance while maintaining a 6ml tank on board. The wicking is just so good nowadays you can push ridiculous power to these things and still get awesome balance.

I think a lot of newer users don't understand the importance of which wire you choose and which wicking material works best for what. You can wrap two coils exactly the same ohms and get completely different vapes. It is much more difficult than some make it out to be but with some good guidance anyone can do it if they have patience. Like anything else it gets easier with repetition.

 

[Oktyabr]

Exactly!

I've had people get peeved at me because I sometimes "make wrapping wicks and making coils sound like child's play".

OK... so it's not "child's play"... but it's not exactly rocket science either! My standby come back has now evolved into "If you can put a key into a lock with one hand on the first attempt you probably have enough manual dexterity to do this. If you can read the fine print on a label your vision is probably good enough to do this too."

I use a magnifying glass setup with "helping hands" from my soldering station stuff.

Helps a lot. Your local R.Shack sells em, and you can get em online everywhere...

 

[Oktyabr]

I have both a set of cheap reading glasses and a dirt cheap clone of the "helping hands" with a clamp on desk light. I wish I would have spent a bit more and bought the helping hands thing with a bigger magnifying glass and built in lights...

Search ebay for 'headband magnifier'.

Besides, after you're done with cigalikes, eGos, and have a couple Provaris knowing there will be no VW upgrade for them where else is there to go?

As this is a forum for new members, it might be worth considering that many of the current trends in vaping are being fueled by complacency or boredom. For vapers that have tried many different devices, delivery systems and liquids, what's new and interesting has a lot of appeal. Making your own coils and juice are very popular right now, partially fueled by fear that the FDA might restrict our choices in the future. For the vast majority of vapers, a good delivery system on a battery you like is about all that's necessary.

There are many batteries and devices that can deliver a great vape, right off the shelf. Winding your own very low resistance coils using a high drain battery on a mechanical mod may be of interest to those who like to tinker, but is not appropriate for many of us. There is greater risk of shorting a battery and possibly making a mistake in winding or battery choice, definitely not something a newer vaper should pursue without a lot of homework or an appropriate background.

The cost savings are, for me, negligible. If you watch for co-ops here on ECF, you can get replaceable heads for many delivery systems for about $.50 each, and they last a couple weeks. If you are going super low resistance, you are using liquid at a faster rate too, so those costs should be factored in.

To me, the best strategy starting out, if rebuilding is of interest, is to use a replaceable head delivery device, and keep the used heads for rebuilding in the future. Once you have a device to read the resistance of your finished work, you are ready to give it a try. If you find it workable and fun, you are ready to start going lower resistance if it interests you. If you can try out a super low resistance setup, you'll find out whether it's something you'll like compared to what you are using now.

I have a couple rebuildables just in case, and should the vaping apocalypse occur, I'll be winding 1.5 ohm coils. For now, I've found that off the shelf low resistance devices on a mechanical mod give me a great trouble free vape. I spend more time figuring out good juice recipes to make.

[D4rk50ul]

It's also fueled by the never ending chase for the perfect vape.

 

[AttyPops]

To each their own.

I never chased "the perfect cig" when I smoked. I don't really chase "The perfect vape" either. As long as I can stay off the stinkies...I'm good.

YMMV.

I'd just agree with 440BB above in post 117...and caution noobs about being careful with these setups unless you know what you are doing. I'm not even going to get into "too hot juice" issues, acrolein production, batteries that vent, etc.
