PSA: Cherry Bomber mech box mod is just that.. A bomb. Do not use.

[Bad Ninja]

I have been using my cherry bomber for about a week or two and its been pretty good until this morning.
I was trying to change the tank and when I unscrewed the tank, the 510 female socket actually un screwed with the tank and that dropped the nut into the case and shorted the batteries one exploded and the other one heated up so high I burned my finger. I had to race to get the thing apart to get the batteries out.
I don't mind when one of my RDAs auto fired. I learned not to use that one with the cherry bomber. But, when you can't simply unscrew a tank without the damn thing shorting out and burning you while scrambling to get batteries out before it explodes... The design could definitely use an upgrade.
I need to find a way to secure the terminal better so it doesn't come undone so easily.

The nut probably came loose because it wasn't tightly cranked down, and the
Left battery holds the assembly snug.

Loosen the battery negative before swapping atomizers.
Mine came loose once after a cleaning and re assembly.

I do remove batteries before swapping attys.

I also use a wide screwdriver at the top to be sure the assembly is cranked down right and proper.

I almost vented a battery once in the Dimiri. I was at a pub showing it off and I put one of the batteries in backwards, creating a hard short. I didn't even notice it until about 20 seconds later. They were hot enough to melt the wrappers.

As for the CB, Bad Ninja is right. The design is such so that when you screw in the battery, you are putting pressure on the pin going to the atomizer. So it doesn't always come apart right unless you take out the batteries first. Also, you won't be able to screw on the atomizer flush if you don't screw on the atomizer first, then the battery. So batteries are first out last in.

Ya, I will have to buy new batteries, and when I want to swap tanks... Take out the batteries first. Ugh, it's tedious.
I feel like I didn't have this problem in the beginning. It's almost like the tighter I make the terminal, the more likely it will come out with the atty.
Has anyone tried a lock washer between the plastic insulator ring and the smooth round nut?

Good idea.
A thin lock washer might work.

 

[vapo jam]

don't own a CB so not going to comment on whether or not it's safe, just chiming in to say this thread reminds me an awful lot of the threads back when we first started building sub-ohm coils. of course, back then, "sub-ohm" meant just slightly lower than one ohm, and you had to be crazy to go down to 0.5 ohms...

regardless, let's stay safe. i think we're all aware that no pv is a toy (even the most innocent ego can be dangerous), and although we may disagree on what's unsafe vs acceptable risk, the path to a great vape is different for everyone.

wow... alot of enthusiasm here... but a bad design is just that... bad.
what would one think if they owned a revolver and went to the range to shoot it and when they did pull the trigger, the gun fired twice instead of once... first firing sends the bullet to the target, the second thru the ceiling ( since the gun recoiled upwards)...
would that be safe and would one consider getting it "fixed"? Now mind you, the double fire thing doesnt happen everytime, its sporadic... never know when its going to happen.. but it does. This gun exists and even seasoned/experienced shooters have had this "glitch" occur to them... Murphys Law prevails... if it can happen it will.

 

[DaveSignal]

If you want to comapre it to a gun, I don't think your analogy is the best. Its more similar to having a weapon with some kind of extra benefit, like a burst fire mode. People who are unfamiliar with the weapon, might not know that there are multiple selector lever settings and so someone who has never used it before may fire 3 rounds instead of 1... and most likely waste at least 2 rounds. This could definitely make the weapon more dangerous in the wrong hands, but doesn't mean that it is a glitchy design. The military will simply train Soldiers how to use and take care of the weapon and where to put the selector lever when firing.

Please do not take this as offense.
It is not intended as such.


It seems you don't really understand how the mod operates.

If you have intermittent firing you most likely have a loose connection.
Probably the copper nut isn't straight and the switch isn't hitting the flat spot.
Re align the contacts to their proper position, and the problem should go away.
Also check your spring. Clones tend to have weak springs. This can hinder performance.
I replaced mine with magnets.
Never a problem. The authentic MCV magnets work fine. The good clones are 1:1.


Just because you don't like the design doesn't mean it's flawed.
Everything isn't for everyone.

following the gun analogy, imaginge that it would fire if you touched the body of the gun and the handle with a metal object and it would fire even if the safety lock was on, would that be a design feature?

Do you have this problem with your CB? Because I don't. It will fire if I try to make it fire, but it doesn't fire if I accidentally touch it against a metal object. It requires some effort. But the fact that it is possible to fire if you try to do it like that is not the feature. That is just how the thing works... the feature is that it works well and hits hard... due to the chosen circuit design (which can be shorted if you try to do it). In fact, any mech mod will self-fire if there is a small tear in the battery wrapper. Is that a design flaw? Are devices that have no protection circuitry design flaws? Are mods with no locking switch design flaws?

 

[DaveSignal]

Look, I've got a ton of mods. Not as many as Bad Ninja, but well over 30 mechanicals. I know how they all work perfectly. I know which ones don't work as well in certain circumstances. I have a few that are really not my favorites due to the way the switch works or the 510 pin sits or how some other part of the circuit is designed. But the Cherry Bomber is not one of these. This is a pure mechanical box that works very well.

Bad Ninja's got more mechs than I do and he also vouches for the CB.

When people with experience have used the mod and confirm it works for its intended purpose without issue, I am not sure why there has to be a flood of other people who have never used said mod to then state that we are wrong.

 

[vapero]

I don't have that many mods, I have 11 mechs, I've built another 5 or 6, I've been using mechs for the past 2 years and I make my living as an industrial designer, I do not own a CB, and I don't plan to, but I do see a flaw there, ok maybe not a flaw flaw but a point of real safety concern

I agree.

I definitely have experience with vaping, ohm's law, battery safety, etc., and I have a slew of devices both regulated and unregulated. As an experienced vaper I see this device as having a very serious flaw. I realize it's expected that you have some knowledge of unregulated devices before you go out and buy this thing, but as it has been proven, people aren't aware/don't care. People will get hurt, and it'll make the argument for regulation all the stronger.

OK, but there are a lot of things in the world that have designs that were chosen despite the fact that they are less safe than other designs. I think that all of the different options should be readily available and the user should be able to choose exactly what product he wants with whatever specifications. If something can be faster, stronger, sharper, or better in any way by applying a design that also results in having less safety protections from user interference with its intended operation, people should still be able to use such device if they so choose. Maybe if mechs came with manuals for first-time users that explained all this stuff, this would be less of a controversy. But I've never seen a mech come with such documentation.

That's exactly the issue.
Not the design. Everything in life just isn't expected to be made for the uneducated, or careless.
Just because an item isn't made for laymen, doesn't make the design flawed.

People will get hurt, and it'll make the argument for regulation all the stronger.

Actually regulations are coming due to a loss of revenue once taken from tobacco sales.

Our government doesn't care if people get hurt.
They just need a revenue stream.

I understand exactly how this mod works... the case is the main conduit of electricity to the switch, the switch makes contact to the - portion of the 510 ( this means the 510 is insulated from the case) and the + of the battery is in constant connect mode to the +510 pin

 

[DaveSignal]

What i was trying to convey was that the cb doesn't fire accidentally, like the revolver in your example. If using the revolver, it would be like a gun that will bypass the trigger mechanism if you jam and hammer a piece of metal into the back of a bullet while loaded in the revolver... The backs of some bullets are accessible to be manipulated in a revolver. This isn't a design fault, its just how a revolver works.

A revolver is a weapon. It deserves a great deal of respect and regular care.

 

[Bunnykiller]

if its used strictly for target shooting, its not a weapon....

lets just say ( for the sake of being a thought experiment) you have the copper CB on a metal counter along with some other metal object on that counter ( umm a fork ) and the mod falls over letting the atty come in contact with that metal object, the counter, the case of the mod... the fork and counter now becomes a conductive route for the mod to fire since it allows the attys - case to be connected to the case of the mod.... and there ya go a situation in which it fires without the button being pressed...

 

[DaveSignal]

I'm never said it was impossible to do. Just that is usually requires some intention and planning to make it work. But yes, given the right kind of unplanned events to randomly happen in the right order and in a very specific way, it is possible for something to happen that would cause the attached atomizer to vaporize juice. And if those chance events happened to coincide with a person who was using an atomizer build below 0.1 ohm, this could end up being dangerous for the parallel batteries, assuming the slim possibility that the coil was able to stay lit for very long before burning out... along with the possibility that the user is using batteries with a CDR lower than 20A installed (so less than 40A CDR for the two parallel batteries combined)... compounded with the possibility that the batteries did actually vent and the mod venting openings were blocked. I think there is a higher chance of a regulated mod exploding while plugged in through a built-in USB charging port.

I could also think of a specific order of things that could go wrong sequentially in order to make the revolver fire without using the trigger. That should never happen though, because you should treat your revolver with the respect a loaded weapon deserves. Always be sure the barrel and action are clear from obstructions. Carry your weapon so that you have full control of where the barrel is pointed. Don't point your weapon at anything you do not want to shoot. Be sure of the target and what is beyond it.

A mech mod isn't going to result in anyone getting killed if something goes wrong. There is a small chance that they could get hurt, though, if they have a blatant disregard for safe practices with their gear and batteries.
