New to RDA's, few questions

[Newff]

Hey guys,

I just ordered a Trident Clone and a IGO-W2.

5.5 year vaper here, but have stuck mostly to 510 atty's. Tried some tanks like Protank 3 (hardly works) and the EVOD (gurgles and floods). I'm looking for more vapor and think it's about time I got into rebuilables. The mods I have is the Prodigy V3 mechanical (6v) and a cheap VapeOnly Vpower (goes from 3.3v to 5v).

1) What Ohms would be best for these mods for most vapor? I just ordered a Trident Clone and a IGO-W2.

2) I'm not sure which thickeness of Ekowool to buy, and also not sure which gauge Kanthol to buy. Any suggestions?

3) I see people using cotton. Is that just regular common cotton balls?

Thanks

Lot's of views, and no takers for your questions eh? OK... I'll giver' a go.

1) What Ohms would be best for these mods for most vapor? I just ordered a Trident Clone and a IGO-W2.
Vapor, if that's your priority, is the product of high blend to 100% VG juice, low resistance value coil(s), the batteries continuous drain amperage sufficient (plus a margin of safety) to support those coil(s)... and finally, adequate air flow.

I'm guessing you have not had much call to familiarize yourself with ohms law and it's practical applications, so that would be the place to start... user safety being the first priority for a responsible vapist, when becoming involved in low & sub-ohm vaping.

At the end of this link is a group of articles, spreadsheets and calculators that offer advice and knowledge about most of the things you need to know to be a safe and happy sub-ohm vapist. If you do not have one, it would be in your best interests to obtain a decent quality digital multi-meter. (DMM)

2) I'm not sure which thickness of Ekowool to buy, and also not sure which gauge Kanthol to buy. Any suggestions?
Is Ekowool a priority for you? I'd venture a guess and say that the cotton, or perhaps still basic silica, is far more popular for RDAs. For the brief time that I worked with Ekowool, I always used 1mm, and folded it as needed for the application. You can make 1mm larger, but you can't make 3mm smaller. ;-)

Kanthal A1 wire gauge is selected on, what I like to call, resistance value optimization. In other words, if the target resistance is 'X', you want wire that, with 7-11 wraps per coil, will produce that resistance. The 7-11 wrap value is my own theory - based on the quantity and quality of heat generated by a compressed coil - as an efficient wrap range for a typical build deck. I find that I use 26 ~ 28 gauge more than any others... but I keep 24 ~ 32 on hand.

3) I see people using cotton. Is that just regular common cotton balls?
Yep... regular organic or sterile cotton balls. Unroll them to the flat condition, peel off a piece size/density appropriate for the application and roll them to fit into the coil with minimal drag.

Cheers

Beautifully put, StateO'. The only thing I'd mention is that the 7-11 wrap guideline would apply really to coils wrapped around ~ 1/16" ID (or jig). Those wrapped around something closer to 1/8", I would then say optimum is in the 4-7 wrap range.

Came to this forum to ask a different question about coils.. and your link gave me the spreadsheet I wanted!

Thanks State,

Before you posts this I bought this stuff below..

A new Mod - Segelei Zmax V3 with both types of batteries.
IGO-L (I planned to order the W2 but made a mistake)
Voltohmmeter
28 gauge A1 Kanthol.
1 meter of 2.0mm, 2.5mm and 3.0mm Ekowool.
1 meter of 1.0mm, 2.0mm, 3.0mm and 3.5mm Silica Wick.

Any tips for the equipment I have would be appreciated. Other than that, I'll read the resources posted.

The Zmax is a regulated APV with an amp limit of 4 amps. Combine that with power output of 15 watts, and your practical minimum resistance limit is 1.0Ω. We don't need a safety margin as the amp limit circuit functions as that.

So there ya' go - 1.0Ω resistance (or higher) is your build goal. With 28 gauge on a 1/16" mandrel that's a 10/9 wrap coil. On a larger mandrel, say 2.5mm, that will be a 6/5 wrap. The wick part will be up to you.

If you want lower resistance, Newff my friend... you'll need an APV with higher amp/watt limits, like one of pdib's .....in' DNA30 customs, or a unregulated mech mod.

Ciao!

Thanks pdib. Gracious of you to say. I so seldom leave the 1/16"-1.5mm ID range anymore, I tend to forget that folks (myself included) still build larger coils.
I'd almost rather switch to a thinner wire when using a larger mandrel, if only to maintain my self-imposed wrap count "ideal"... but then wrap count vs. wire gauge is a whole different and highly arguable "can O' worms".

Glad to help. That's why I wrote the "big article O' links", Backlash - a catch-all for useful mech and RBA user type information... although some of it is more widely applicable.

I do update it as I find info that fit's well into the concept... so if you see something that belongs, give me a shout. ;-)
