So I love the Ehpro clone Atomic rda...so much so I bought 3 of them to stick on my milled Grands.
I've been milling down and tweaking my Grands for sub-ohming for a while now. I found an Ever ready flashlight that has the perfect chunk of spring brass that has been able to take what ever current I can throw at it (but I'm still trying to find that elusive beryllium strip). At any rate, I've been getting some decent v drop numbers in the .3 to .25 range but there's still that last connection point where you lose...the 510.
So I got rid of it, I took one of my Atomics and removed the center pin and replaced it with a brass machine screw. I them milled one of my Grands right down to the deck, I drilled out what was left of the stock 510 and pressed a brass 510 barrel in there. I then drilled out the 510 barrel so that it was basically a threaded hole. I then took the brass machine screw (removed the head) put it in the lathe and drilled a 1mm hole up the center then "T'd" it with a 1mm horizontal through and through hole where it would be flush with the Atomic's deck (for good suck-back). I then drilled another 1mm hole right at the top of the machine screw for the coil leads (trapped by upward pressure of the spring I scrounged out of an RSST). The brass disc that holds the firing strip is a machine nut I just made round for something to do then I turned down the end to take the feeder tube....the end result, on my Fluke I finally hit the .2 drop mark on a .5 ohm build...
Of course this is now a single unit (though I could always make other center pins to work with different rda's but for now...the Atomic is one of the best I've used and I've got 3 other Grands so meh...just throwin' it out there...btw, the juice bottle is a 10ml bottle I get from Bogger...they "just" fit (with no flappin' around, I hate that)
