Megan 26650 clone just wont fire

[dykealiscious]

THIS THING IS DRIVING ME NUTZ! Not a beginner. I've tried every manner of adjustment. Every atty...i have 12. Authentic squape with the pin extended is the only one that will fire. I've tried the others with extending 510 pins and they just don't seem to make contact. I've read of others with this problem but no solution offered. HELP or I'm gonna sell it.

When you ohm out your switch does it toggle from 0 ohms to infinity?

Good question. If I could find my multimeter I'd tell ya lol. Still looking. In the mean time I'd assume I'd want to remove the switch cap, and put my leads against the center pin and outside ring? Havn't tested a switch before.

Exactly right. Outside threads to center pin.

Have you done recent service on it? Or is it neglected?

edit: I missed the part about your Squape working. Is that top pin a press-fit? My guess is that if it is press-fit, all you gotta do is push the pin back upward a bit and let the atty drive it back down.

Ok so I found it. The reading just perpetually jumps around. For comparison I tested the neg pin and surrounding cap and got the internal res if the meter, which I would have expected.

I have a theory that the top cap is the problem. Unlike a lot of my mods, the pin in the top cap is seated in delrin in such a way that it never makes contact with the 510 threading lending zero conductivity to the cap and necessitating that the rda MUST make full contact with the pin, and it is a deep well. Most of my other mods have the pin in contact with the threading so any rda that doesn't reach all the way to the pin isn't a problem. Thoughts?

You can see the pin in the top cap surrounded by delrin here:

And from the bottom...

I don't know if the authentics are like this too. Other references to this problem all seem to be clones.

Authentic squape is a screwed fit. I only have 3 rdas with adjustable center pins. Squape has a naturally longer 510 thread. The other two are shorter and the pins don't come out that far. They won't connect with the top cap pin. Problem is squape has low airflow and the hole is in the threading, so it is a terrible pairing. I bought a geyser to go with the Megan and the pin won't contact the top cap. I think if I could find a longer top cap pin to swap out with what it came with that might work....I dunno this sucks lol.

And it is out of the box. Been trying to get this thing Megan to work since purchase.

Did I mention the terrible battery rattle if I don't adjust the top cap pin to fix that leaving me with only the option to adjust via a given atty?

Ugh what a terrible design. That top pin is a cap with a spring and then another smaller cap. ... man.

No I'm talking about the pin inside your top cap.
Sounds like you need to push it upward to make contact with your atty pin, but in doing so you're getting rattle.
Your switch has to be able to account for that extra space, and if it can't, I'd use a magnetic spacer on the battery positive side. I use one in my Akuma since I hate the adjustment pin.

 

[duc916]

Anyway, sounds like you got it nearly figured out. Once again, another mod over-engineered for adjustability, under-engineered for reliability.

SMPL ALL DAY.

So looking at videos other top cap pins are double the length as they are 2-tiered. Looks like I have an incomplete piece. :-(

What i have doesn't push upward, it is rigid because ostensibly it is missing a piece.

Also have used a battery spacer and that doesn't seem.to help.

Is that any chance made by Tesla? I went thru that same thing with a 26650 vanilla by Tesla. I trying to find a new center pin for the top cap. Check that your pin is screwed in completely, check the delrin to make sure its driven in completely, then take a measurement to the top of the pin. check your attys, (all of them) to find the shortest one, and allow a bit for adjustment, and there's, the length of your new firing pin

Yea I do believe it's the tesla. The pin is actually in 3 parts. There's a nub in the delrin, a spring that fits into the nub and also into the screw that ultimately connects to the battery. One would think that means it is an adjusting pin. It doesn't move at all. I do believe there's a piece missing.

Where would one find a new pin anyway? I've looked and other than some non plausible options from fatdaddy I don't know what to do about it.

For a replacement pin I Went to lowes, bought a foot of 6g Solid copper without the sheathing then went to the plumbing department and asked them to thread about 4/8th of an inch for me and left a little nub at the top so I could torch it and mold it with some rubber tipped pliers.

This was a complete PITA btw, Im sure you can find a better pin buuuuuuuut now its basically like a manhattan pin, straight through.

Btw threading the pin was an EVIL thing to ask a worker to do, but the cool thing about it was he vapes too and knew excatly what I wanted it for.

He uses the threading machine to thread the copper tubing lowes has, oddly enough theres some solid copper pipe just big enough to fit 18650 with little wiggle room and 26650.

EDIT, If you do this, your pin is now the contact for both the battery and your atty.

That is awesome.
