EHPro Bachelor RTA - single coil

[JeremyR]

Oh, just pulled mine out and it's a two piece. Hmm didn't realize that.

So there's another copper in the end of the air tube. You can see it sticking up in the air tube if you look through.. If you could get in there and push that down then you would have plenty of contact.

They must have pressed it a little too far during assembly.

It's still early days (minutes) but it sounds better so far.

I'm looking forward to the Nano version for my PICO.
I like this full size and its features and just don't feel like wading through all the other tanks out there. Too damn many to choose from.

...scrub-screws neither (I think that's what those are called anyway?).

It's "grub screws", for the little headless jobbies.
I think that's the defining characteristic.

I still have one o-ring left to replace it with, but just curious, how do your two o-rings below the coil compare to each other. From the start the one below the screws that hold the coil in has been thinner than the one above the screws. Is this suppose to be this way or could that be at fault perhaps?

This is not true for me. Both of my tanks use identical thin O-rings above and below the threading, no protrusion at all. So that explains the chewing. I'm so glad you looked inside the chamber dome! This thread taught me to keep a sharp eye on that one. One of my tanks had it loose at unboxing, but I was able to re-seat it well and it hasn't budged since.

Now I hope you can enjoy it as much as I do! I'm looking forward to your thoughts on the Nano version.

It sounds like it's figured out, glad you have that one last correct oring maybe..

Why in the world they didn't send more extras is beyond me though.... I would have gladly paid 1.00 more for another set of orings and top cap seal.

 

[OhTheAgony]

The seal that sits in the chimney, if you noticed, is a flat seal instead of an oring.. And the one under the glass is a flat seal too. Mines never fallen out on me, but I knew about it before I got it so I was aware. It stays in there pretty good for the most part.

So it hasn't been in since the beginning, that is definitely the problem...

For the short pin, A small oring would work well under the pin head. Or any old seal you can make fit under it to raise it a little...

I've cut orings to fit before and it worked well. If you have one the right thickness to fit, cut it so it makes a ring around the pin and push it in.

I'm not really sure what I put in the chimney to be honest. It may have been one of the two that are suppose to go on the bottom but it fits ( a bit loosely, but it was moist from e-juice in there so it stuck to it and it seems to work for now).

I still have the spare flat one that goes underneath the glass so at least I know it isn't that one, lol

But in hindsight it is possible that I stuck the one that's suppose to go up in the chimney in the spot where it is now being shredded, so in that case it would my own dumb fault again causing that problem as well (also a reply to @man00ver's last post).

I really can't be sure until I get another complete set of o-rings to compare to the ones I have left though.

When I first cleaned the tank before use I let it soak in hot soapy water for a while and then brushed it out with a toothbrush, so that would have definitely moved the o-ring out of the chimney.

I had read about a loose o-ring you'd have to keep an eye on in this thread before my Bachelor got here but it wasn't clear to me which one it was or where it was suppose to be exactly and I only noticed it when going through this thread again this evening and came across a picture someone took of theirs.

As for the pin; I cut a tiny bit of a 1mm thick copper wire and flattened it with a hammer on an anvil and stuck it in there underneath the pin. As your namesake Jeremy Clarkson always says; anything can be fixed with a hammer

If I hold it to the light there's still a tiny gap between my mod & tank but it sits almost flush now.

It's still early days (minutes) but it sounds better so far.

Ah, gotcha, thanks. I knew what it sounded like but I wasn't sure of the exact word, lol, like I often have with English words I haven't used before

Isn't 'grub' also used to describe army- or prison-food though..?

Alright guys, it's the middle of the night over here again, time to relax a bit and enjoy this Bachelor finally before I get some sleep.

Thanks again for your input everyone and I'll be back

Oh, and it's still dry!!!

 

[JeremyR]

These things happen for sure..

... I call them set screws cause thats what they are.

 

[Jim_ MDP]

Yup. I'd never heard "grub" screws before vaping.
No idea the origin of the term.

They look like grubs (insect larvae).

 

[OhTheAgony]

And since grubs are edible and protein rich I guess we're back to food again, lol

Oh, it's still dry!

I did close of the JFC when I went to bed last night, just in case, but whatever I stuck in the chimney kept the juice in there as it should.

Problem fixed!

Hopefully the vendor can send me another set of o-rings

It does consume a little more juice then my Toptank though, but I also vape a bit more because I enjoy the vape from this tank more.

So I better start cooking up some more juice before I run out!

This creamy banana stuff is pretty addictive, real good with my morning coffee as well. I think I'm gonna mix in a little brown sugar with the next batch..

I had the same problem with leaking and yes it turns out it was the o-ring on the inside part of the chimney, where it starts forming a cone.

The problem is that you don't know there's an o-ring there since it's see-thru! So I lost the original one when cleaning my tank and never realised it. I think most people have the same problem.

Yeah, they really should put a warning about it in the manual or on the package. If I was someone who bought this in a local store that doesn't use internet forums I probably would have never found out what the problem was.

On another note; I just noticed that my Nano is expected to be delivered tomorrow already!

So it's time for banana-man again



4 days from China to NL, that must be a new record!

I expected it to take a week or two at least, and to be honest I also assumed Heaven Gifts was based in the US, lol

From what I gather the Nano has slightly more airflow then the regular Bachelor so I think I'm gonna swap the bases of the two. Seems to make more sense to have the larger capacity with the bigger airflow anyways.

Gonna treat those o-rings like they're made of gold though!

I received mine a week ago and this thing is driving me insane.
I tossed the first coil (that large one) and built and wicked one myself, everything worked great even though my coil building skills are not the best.
A couple of days later i decided to rewick it and after a while of vaping when i was going to switch tank on my mod i noticed a little ring of e-juice that had seeped out from under the atty.

Rewicked it again to discover the same problem every single time, i rewick several times s day trying to get rid of the little leaks. I want that perfect non leaking experience like my first days.

I googled it and found this thread. I've checked the o-rings and they all seem fine to me so the main issue must be my build/wicking. I make a 26awg 3mm id kanthal coil and my wicking method has been a bit like the scottish roll lately.

This is pretty irritating since i like this rta more than my Bellus and my Gemini aside from the leaking.

Any tips?

i have gotten that little circle of juice before. i think it has to do with the wicking because the next time it wasn't there. not sure what i changed other than going up in diameter on my coil so i can fit more wicking in.

 

[MMW]

Are you sure that you have the oring from the top of the chamber in?

Tried a different wicking method now, instead of fluffing it and gently rolling it i just cut a strap, pinched and rolled it pretty hard and put in in place. Noticed some juice under the afc but it could be from before, i guess i'll know how well this wicking worked in a couple of hours.

Yes, check out this image

 

[mgmrick]

It does not matter what atty I have built...

More is better.

 

[man00ver]

Yes, check out this image

Well my eyes aren't what they used to be, and that picture is a tiny bit fuzzy...but it looks like the O-ring is missing inside your dome. I see the outer groove-wall with nothing in the way.

I think the loose dome-ring is the #1 problem with this tank. It WILL lead to a seepage problem.

Nope, it's there, im sure. Its just a bit juiced up.

I try to get as much cotton in there as possible too.

I'm just repeating tips others gave to me before, but could it be you're having your wick touch the two tiny holes on the deck perhaps or got some in between the o-rings and the casing maybe?

 

[OhTheAgony]

Woot, got the Nano I won in a giveaway from Heaven Gifts today, thanks again @AlmightyEvan !!

They were also nice enough to include the MTL kit. I don't think I'll be using the more restrictive air-nozzles from the kit but I really like the more restrictive drip-tip that came with it.

Let me start by going in to the o-rings to clarify the problems I've been having with my regular Bachelor:

It's clear to me now that there's nothing wrong with the Bachelor I got, except maybe the shorter 510 pin I had to work around & of course the broken o-ring it came with right out of the box.

As it turns out the broken o-ring that it came with was replaced (by me) with the wrong one, one that belongs in the chimney instead. So that is what caused it to shred, it was simply too thick for where I put it.

The one I put in the Chimney last Sunday after finding out there wasn't one in there was the right o-ring though, which can only mean that it came with two spare o-rings for the chimney, but no spare o-rings to put on the base of the build deck hence my screw-up.

The Nano did come with one spare for the base as well as one for the chimney so with that set I was able to make sure I have all the right o-rings in the right place on both my Bachelors now. Both have been completely leak proof since, so far anyway (if it changes I'll let you guys know of course).

Ok that's that, back to the Nano:

It really is very similar to the regular Bachelor, the only difference I could find is this little stop-pin on the airflow control of the Nano:

My full size Bachelor does not have that pin.

Other then that the airflow holes on the Nano are approximately one mm longer then on the regular Bachelor but otherwise they seem pretty much identical except of course for the different capacity.

The airflow might be slightly less restricted on the Nano but frankly I find it hard to tell a difference, so if there is one it is really close.

edit: I forgot to mention that the copper 510 pin on the Nano wouldn't connect to my Evic neither without shimming it, but that's probably the Evic's fault.

And another observation; the airflow control on the Nano is much stiffer then on the full size model. On the 4ml version I can just lay a finger on the ring and move it around, but I need to grab it pretty firm on the Nano to move it around. I'm very happy with that.

What else to say, I really don't know, lol

Lets finish with some more pics. My indoor pics always suck but the weather is too bad to do an outside shoot right now. I'll try again when we get some better weather though. For now these will have to do:

28g grade 1 titanium, twisted, 8 wraps with an ID of 3mm, comes in @ 0,37Ohm.

And finally:

If anyone has any questions or pics requests just say the word.

Cheers!
