RDA and Mech Mod Intro

[oldhippydude]

I'm thinking it would be better to start off at a higher resistance then. But looking at the online calculator, using 24AWG I would need to do 12 wraps for a resistance of 0.5ohms. Does that sound right? Seems like more wraps than I've really seen before

I like 6 or 7 wraps generally.
4 or 5 min 8 or 9 max.
That is just me.
I use wire that allows me to to build the coils I build.

Get back on the calculator and find a wire that allows you to build the coil you want.

No, 12 wraps won't work well. Even if it fitted, which it won't, it would take too long to heat up.

If you want higher resistance, you'll need thinner wire, or...

... Start off using the Drop Dead in single coil mode with the 24g wire. That will double the resistance.

Ahhh yes good thinking, thanks! There's so bloody much to consider when using RDA's and mechs Hopefully I won't regret it!!

Of all the reasons to buy a mech "it looks sick" is not one of the best.

If you're trying to replicate that kind of heat, that would suggest building to around 0.18 ohms, although, an RDA with a smaller chamber or tighter airflow can also boost the heat. It's all down to experimentation. When I use a Drop Solo with a 0.3 ohm build and only two airholes open, it feels plenty hot.

There's got to be worse though

And you recommend this build as a first ever build on your first ever mech?
I would advise leaving a bit more margin for error on a first build.

Hopefully I don't come in Monday with a) one hand and b) put off RDA's and mechs for life

At least you are doing your homework now and asking the questions.
It would have been worse to dive in without a clue.
Keep at it and it will all be so simple soon enough.

My advice to you is to get used to using building on the RDA using it as a single coiler.

You've got to learn how to wrap a coil, using a 3mn diameter rod to coil it around. Do you have a coil jig? Or are you thinking of using something else?

Then you need to get used to installing the coil without deforming it too much, which usually means using the rod you wound it on to hold it as you screw it to the posts, then sliding the rod out.

Then you need to bed the coil in on an ohms reader or regulated mod, gently pulsing it to check for hot spots and squeezing it and strumming it until you get it glowing evenly from the centre outwards. You'll want some ceramic tweezers for this so you don't accidentally short circuit the coil and to insulate you from the heat - if you use a metal tool to do this you have to keep waiting for the coil to cool before you can work on it otherwise the metal tweezers will get too hot to hold, and you can't squeeze the coil whilst pulsing it like you can with ceramic tweezers.

A spaced coil is easier to bed in, but that's another step on your coiling journey. You'll still want ceramic tweezers.

What do you have in the way of a building kit?

Now, with dual coils, you need to do all that twice, ending up with two coils that glow identically when pulsed. This requires you to make 2 identical coils and get them both bedded in so they are glowing in a perfectly balanced way.

Don't try to run before you can walk.
