    I have a Nemesis clone that I use as my primary device lately. I'm wondering how in the hell the bottom pin unscrews itself all time. I have to screw it in a few turns about 2 times an hour. I'm not familiar with Loctite and don't want to mess up the switch but think a non permanent form of that may work. Any suggestions or experience about this issue would be cool. I use flat top 18650 batteries and the atomizer is always secured with the top pin. Never any battery rattle. Just a bit perplexed as to why it unthreads.

    The reason it unthreads is due to the spring. When you press the switch the spring induces some axial torque, overtime this causes the pin to loosen.

    Go to your local hardware store and pick up and internal tooth lock washer. It will keep the pin tight and reduce the switch throw to about 1mm.

    Will do. Thanks. Would you recommend the cheapo Fasttech magnets?

    Not sure to be honest, haven't used em. I have these coming in this weekend SuperMagnetMan. Still unsure if i'm going to keep the nemesis or not though even when the magnets do arrive.

    No, get the magnets from FatDaddyVapes.com. Also get the pins from Fatdaddy, It's easy to get the switch pin tight enough.

    This is definitely an easy and proven fix, but a little more costly. The same can be accomplished with the lock washer, a file, and the 10 magnets from supermagnetman. But if you aren't into tinkering, then yes FatDaddy is definitely the go to solution.

    Fat daddy vapes does not have the contact screws. I am either overlooking them or they took them off the site?

    All they have are the magnets and the Top cap Delrin insulator piece.

    I just looked and you are right. Which is weird... I just saw them a couple days ago. Must be out of stock.

    Interesting theory -unfortunately incorrect. The pin can turn on its own even in a Magnetic switch configuration.
    I Know, all mine are magnetic.

    Then it would probably be from your finger torguing it.

    Instead of Loctite use a bit of finger nail polish on the pin threads. Does the same thing.

    Similar thing happens on the Magneto.

    Just from firing it right-handed, the switch inadvertently spins out from the locking ring in the switch ...'y. You know when it's getting bad if the locking ring begins to freely spin instead of stopping.

    If the magnet comes loose, the damn thing makes contact and fires the mod. Busardo covered that very problem in his review, as it's apparently very common on the mod.

    Unfortunately, my situation is unique as I can't just unscrew my bottom cap, because it's implanted/overthreaded too tightly. Can't get it off to save my life. So I have to push the negative terminal down, while depressing the switch, and spin it clockwise to re-tighten it and it takes FOREVER.

    It's a real blast.

    I'd seen pictures of Nemesis switch setups showing the lock washer (along with magnet shims, but those I understood) but never understood what purpose it served. Thanks for explaining.

    Do you know why it unthreads?

    The same reason people find the Nemesis firing button to not work right and try to fix it with magnets rather than addressing the real problem.

    The real problem is the Nemesis was designed around button top batteries and has about 1.5mm more room inside than the average flat top. In order to make flat top batteries work you've got to leave the pins slightly loose, which allows but the bottom and the top pin to unscrew with use.

    If you REALLY want to fix the problem then don't waste time and money on magnet kits or washers, just switch to button top batteries.

    I use button tops and my pins are always nice and tight. The pins do not unscrew themselves, there is never any crunching at all from the (still spring loaded) button, and it never ever misfires. The only time I open mine up is when I want to change the topper or the battery. I never have problems with the mech itself.

    Just take out the small trim ring or use a 3mm battery magnet. Both the silver contact screws are designed to be tight, not loosened for battery length adjustment. Poor instructions from the original maker led to this confusion. The only adjustment, rather than altering the tube or battery length is the entire switch itself. If the bottom silver switch screw is not tight (I snug with pliers), the screw will loosen.

    My nemesis doesn't even come lose, the pins are always pretty snug when I've gone through it. I also use flat top batteries, without the thin beauty ring. No problems.

    Grease for the magnets?

    I wouldn't call it a waste of money and time, magnets also serve other purposes like being able to set down the mech without firing..... besides, a few magnets and a single washer are not going to break the bank nor take much of ones time. I have done much worse with my time and money and we all know that.......reason why we are all vaping now :laugh:
