Safety of Mechanical MODs

[NOMINDTR]

Hello,
I have been posting some questions about mechanical mods and got very useful information from senior members. I want to move to a mechanical mod for following reasons.

1. The basic, ego type kits I used so far didn't give me a good vaping experience. Leakage with automatic types, charging, discharging issues with manual.
2. Whenever there is a replacement needed, I have to pay ten times as it costs on fasttech , we have few options in India.
3. I vape 3ML a day. The basic types I have been using don't support that.

So I thought I should move to an eTwist like thing, then thought a Nova MOD should do better. But I was not convinced as I have been troubled by what is available in India. Realized a mechanical MOD should be OK for it's doesn't require frequent replacements (thought there are indirect replacements), the battery is available with nearby store. I can always customize the coils.

I was suggested to get VV/VW Mod first, as mechanical mods have safety issues. I understand that. for example, if I use a 1 ohm resistance coil head and my battery supplying 5 Volt, or if I build a sub ohm by mistake, things won't be smooth and easy. But I was wondering are there a procedure, following a protocol that should help a first timer with a mechanical mod. So wanted to post here this question so that I can decide myself if a mechanical thing would suit me or not.

What are the primary safety issues with mechanical MODs and ways to prevent them?

Thanks in advance.

Here are my thoughts.

I should use a measure the resistance and voltage output to know what I am building with what
I should use a protected battery like LiMn, of a reputed brand
I should always have an eye on the way I handle the mod considering the wattage it would produce.

Thanks

Well the most important thing (IMO) you'll want to know when dealing with a mechanical mod is Ohm's Law.

Ohm's law - Wikipedia, the free encyclopedia

It will tell you everything you need to know about what kind of amps you'll be pulling with a certain resistance/voltage, etc....It will also tell you the lowest you can go resistance-wise with a given battery's amp limit.....

When using a mechanical mod, paying att'n to the amp limit of your battery, IMO, is the most important thing you'll want to do. You'll want to make sure that your contacts/threads are clean, and that you're staying within the amp limits of your battery.......

If you have the tendency to brush off or discount the math involved with using a mechanical device, then it's probably not for you.....It's really important that you understand the relationship between your battery, atty, and mod......As long as you're diligent about staying within the "limits", then you should be OK.....

The battery suppose to produce varying its highest current (in amps) at beginning. It will be producing less and less over draining. The highest current (amp) should be noted. Is this understanding right?

Somewhere I read the number of winds of the coil too determines the effective resistance. So beside the inherent resistance of the coil material, the way we wind too contribute to resistance?

 

[supertrunker]

Only the length of wire between the posts determines resistance. Coil-making, reliably, accurately and repeatably is crucial for mech mod use, because that's the only way to get the vape you want.

You can think of a mech as variable resistance.

BUT - there are no safety features built in, so you MUST check and double check your coils to make sure they are not shorting and not loose. The only safety feature, if there is one at all in a mech is perhaps a spring that will collapse if you run too much power thru it. So, the onus is on you to make sure everything works as it should.

Having said that, once you can make coils you like and get to your vaping 'sweet spot', you have ultimate control over your vape and apart from changing out batteries when they get weak and the vapour production subsides, they just keep on going.

The length of the wire determines resistance. You should buy a digital multimeter, and you can (if you want) also get an ohms meter.

This is a free app you can download that will tell you how long to cut the wire https://play.google.com/store/apps/details?id=com.valsoft.vaperstoolbox&hl=en

Always measure, btw.

Thank you very much for the resources.

Thanks. How would you build coils in general?
Building few in row with desired characteristics, and checking them should help initially I guess.

Very useful and am getting some leads for further research

Hi Nomindtr

These guys have definitely given you good information. They are some of our best "Mech" heads. I am going to tag in here with another good resource...

Baditude's Blogs

In particular, numbers 7,9,11,12,14,15,16 and 17 relate to running a Mechanical mod safely. Pay attention to the Continuous Discharge rate of your battery...=)

Personally, I am a big fan of regulation because I like that extra safety factor. Many here run mechs quite safely but as these guys have said, to do that takes diligence and vigilance....you are going to tinker quite a bit.

Enjoy!

How the spacing is measured and controlled while coil building?

Many thanks for blog posts. Should be of great help

How the spacing is measured and controlled while coil building?

You are going to wrap your coil around something...most of us use a drill bit (or wire mesh for Genesis style atomizers). Also, most of us wrap the coil so that there is no space in between unless you are using a Genesis-style atomizer.

If you notice in the coil toy, spacing or no spacing still requires the same number of wraps...you just use more Kanthal wire to build the same coil at the same resistance if you leave spaces between each wrap. I believe this is more a matter of how small the deck of your atomizer is. Also, if you are using a Genesis style atomizer you are likely wrapping around wire mesh and not a drill bit.

At the end of the process, regardless of spacing or no spacing, the coil should fire first from the inside wraps and out to the ends with no cold spots (not heated or dark).

Can't speak to building Genesis.

What atomizer are you trying to build?

Figured it. (no spacing)

I am not really building a coil NOW. Preparing a list of arsenals for placing an order
When I bought an eGo, I really "jumped into", was comfortable with little research. Don't want to do that again, especially with a mechanical mod

If you will allow me to recommend something....a Kayfun Lite Plus v2, (or clone) is a very easy build for new builders. You might start with one of those to get your feet wet. Here is a video that shows you how to build one....LOL there is a mute button...but please promise us that you will have Ohms Law and the battery specs down dead cold before you start digging in to building...

BTW, I would not start with the Chimney coil...do the regular one first.

Thanks. Please suggest what you think fit. Do you have any opinion about the material of the MOD. I LIKE copper. That doesn't mean that I prefer copper Any suggestion?

I will defer to our Mech Experts on a good, pretty mech with sufficient venting....guys?

Oh and don't forget you will need an ohm reader or multimeter....check out the Baditude posts, he recommends one.

Sure, will get a multimeter

If you use a multimeter...just remember that the leads themselves have a resistance which you will have to measure and subtract from your reading....
