I got a Erlk clone from FT and had major problems with it for a little while until I figured it out. Of course it was dirty, dirty like no other atty I had ever bought. But even after a god cleaning it would run good for awhile, maybe half a tank, and then it would start having symptoms like a connectivity issue was developing. vape would be inconsistent or cut out all together. One thing I noticed was it would wobble a little bit even after cleaning it, getting it back together nice an tight, it would just start to wobble after a while.

The problem was in the 510 connector, and the way it seats into the deck base. Obviously this is supposed to be a nice tight "press" fit, but with the fact of less then precise machining, and the secondary fact that a nylon plastic nut holds it altogether, it would just back off and start to wobble after a few heating cooling cycles.

This is how I tightened it up, by putting small peen marks to each straight side of the deck hole, it would allow a press fit on the 510 connection and it has been fine ever since.

This is what the four parts of the deck look like, the nylon nut is third from the right, technically it should be on the far right in order of dis-assembly. I must stress you have to be very careful with this nylon nut, ham fists and bad fitting screw drivers will tear it up easily.

Here are the peen marks put on both sides of the bottom of the deck. The deck will fit upside down in a small vise with some protection so it can be done safely, but you have to hit it soft because it is fairly soft metal. If you are not familiar with peening anything, try some scrap first so you get an idea of how light the tapping must be to produce these tiny marks. Notice the peens are slightly towards the center of the hole, because the 510 connector is rounded at the edges of the square.

Next you need to put a slight bevel on the 510 connector to help ease these two parts together now that they have been made smaller. The bevel is the very bright slope on the right side of the top flat section here, it needs to be done on both sides so the 510 will just start to slide into the deck, but not go completely in without some muscle.

Then I started the two parts together carefully so they were lined up good and square, the bevel and peens marks should allow it to go about half way home before it stops without undue force. And I then just set it upright on my bench and gave it a good push with my fingers, putting my weight onto it, and it popped in with a fairly loud pop.

No more wobble. :?)
