1st Timer: Mechanical Mod

phiberdsn · Oct 6, 2015

Hey Guys,

I had posted this in my introductory thread but I should have posted it here..
I have a question about mechanical mods and even though I've done countless hours of research, I haven't been able to come to a conclusion because it seems like definite answers come more often when a specific device, atomizer and battery details are provided.

I have the following items that I'd like to use as my mech. mod setup but I was wondering if I should be aware of any faults with this setup?

- Fuhattan mod (copper with centre pin)
- Tobh Atty V2 (copper)
- Battery (Sony SE US18650VTC5, 2600MAH, 3.7v)
- Nitecore D2 charger

If I were to build a .45ohm dual coil build in my atomizer, I would be pulling about 9.3amps (continuous discharge) at full charge (4.2v) or 8.2amps at 3.7v. Viewing the specs of the Sony battery, it says "Maximum Rated Continuous Discharge Current: 20A" - I presume that the battery is suitable for the build/setup. Correct?

Any help, critique, suggestions or general knowledge would be great. I am completely open to earning and would appreciate the help.

Thanks,
Stan

I forgot to mention that I also have a Samsung 25R... doing some quick reading, I've seen that this battery might be better because it doesn't run as hot as the Sony VTC5?

Yep.
You are good to go.
You are well within the battery's limits.
Check for shorts first and you should be fine.
Either battery will work fine.

B2L · Oct 6, 2015

Both batteries are excellent for that resistance, the VTCs would be better if you were to decide to build lower. Check out @Mooch blog for great battery info.

Just remember when building dual coils, half the resistance of the individual coils to figure your over all resistance. IOW, to have a final resistance of .45 you would need 2- 0.9 ohm coils.

Just make sure to test the build on an ohm meter before putting it on your mod, even putting the top cap on while on the meter to ensure there are no shorts.

Welcome to ECF and the wonderful world of mechs!

Sounds like you've done the legwork. Only thing I'd add is that for making coils, a cheapo 510 ohm meter is worth 10x any Fluke multimeter. Why? One word: resolution.

phiberdsn · Oct 6, 2015

@B2L and @duc916 thanks for the tips - I found the battery info by @Mooch and that is huge help.
I already have the Tobh Atty built and it comes in at .44ohms (dual 26g Kanthal) using my eLeaf meter and I also tried it on my iPV D2 but the numbers were slightly off (.44/.47).
I've heard that ohm meters can be slightly off from one another but seeing how the numbers are relatively close, I should be OK.

duc916 · Oct 6, 2015

Yes! if you already have a regulated box mod, no need to spend any more. :thumb:

Yes, mass produced meters are going to vary some but it sounds like you are doing your homework, checking and double checking your build and asking good questions. If only everyone who got into mechs would initially start out like this they (mechs) wouldn't have a bad rep.

Feel free to ask any other questions and enjoy the journey!

Yep good to go.
Nice to see somebody new to mech's taking a sensible approach. Seems like a lot of people start out with a build that's right on the limit in terms of safety.
Enjoy!

Haha thanks - I''ve spend about 2 months doing research on mechanical mods before purchasing. All the help from ECF has given me more confidence.

Setup is fine, but, I gotta throw my 2 cents in...may want to reconsider a stainless steel atty. I first started out dripping with a brass TOBH from FT and my god it was awful. It never tarnished evenly with my brass mech, so it would be two different shades of brass, ugly. And most importantly, after about 5 minutes of use, the top cap and sleeve would tarnish internally with this nasty green color that ruined the flavor of my juices. Probably leaching lead for all I know. I ended up throwing the top cap and sleeve away and bought some cheap poly sleeves and chuff caps so I could at least salvage the base.

My opinion is literally only worth 2 cents though, I see a lot of people rocking brass and copper drippers who have no problems, but just seeing them makes me cringe now LOL

edit: Not to be persnickety, but what made you decide on a TOBH in the first place? There are a thousand and one side air drippers out there now like it, but without such limited airflow, no tabs on the deck, and better posts.

Thanks for the tip - I'll keep my taste buds open to see if I notice any flavour or tarnish issues. So far no issues.
I was thinking of getting a stainless atty in white to match my setup - maybe I'll see the difference then!

javyn · Oct 6, 2015

Oh no, if it's working fine for ya, it's working fine. I noticed almost immediately I got a piece of junk LOL.

lol my Tobh Atty in copper looked decent when it arrived, quite happy with it.

javyn · Oct 6, 2015

Nice looking rig you got there! I like the white.

javyn · Oct 6, 2015

I'm considering this bad boy right here next:

Thinking about doing what you did, white mod + whatever atty + one of my white POM drip tips since I have a ton of them.

I actually have that atty.
I've never had a problem but I clean my gear pretty often.

I've never had a taste issue with brass atty caps or brass taps on my water plumbing.

Thanks to the fearing mongering and uneducated kids on FT, there are very few brass atomizers available.

javyn · Oct 6, 2015

Speaking of fear mongers, brass atty on a Cherry Bomber....

I kid, I kid.....

Thanks, gonna have to wait for some reviews on this though before I pull the trigger!
