Thanks Robert, I did try some things similar a few days ago but didn't notice much difference in TH, mainly only the amount of vape. I'll play around with it some more.
Well, some of them are sweet. It's a bit of hit and miss. The one I had was great, until the negative post got wobbly and fell off
Hey, Darkzero, where did you buy yours?
I got mine from SunVapors since they offered quanitity discounts & were closer to me. The SS RDA clones have SS bases & the ones with the AL caps have brass bases. The posts on both versions are brass. SunVapers does mention the ground post can move & say to use pliers to hold it in place if needed.
On my first SS RDA mod I scratched up the post when removing it. At first I did not realize it was just a press fit but I suspected that by their description about the pliers. After machining the juice well the post was pretty loose because the juice well is half way into the post's hole. I used pliers with sharp serated teeth on them & pinched the end of the post around the entire diameter. This created a sort of knurling which made the fit tighter, used the arbor press to press it back in. The post on this one is still a bit wobby but it stays in place & does not rotate when tightening the screw pretty snug.
On the BR/AL version the ground post is also probably pressed in but on the one I'm using now it doesn't have even a slightest bit hint of being loose. And I even rotated the post to line up the coil holes to where I wanted. This time I used a vacuum cap to protect the post from damage & it took a decent amount of force to rotate it with pliers. Give the pliers trick a try, you could also add a bit of threadlock on it before pressing it back in but not too much. As long as it's a tight press fit, it should disperse any excess threadlock enough where the post will still make sufficient electrical contact with the base. Just be sure to clean off any left over residue of threadlocker after giving it sufficinet time to dry.
