My father in law picked me up a 19e from 101vape for my birthday. It has a spring for the top contact and a magnet for the bottom. Lots of misfires. Looks like I have a little modding to do.
I've flipped through the thread a little and still have more reading to do. Here's a couple of questions.
The magnet is split in two. What do you guys think of grinding the access out and filling with silver solder.
As for the top, could I just remove the spring and put a brass machine screw in or should I just leave it.
If you're going to use an 18350, you'll need to put a screw in that top cap cause the battery to too short. If you're going to use a 18490 or 18650 you can just unscrew the spring and toss both the spring and the screw. The round piece left is the bottom of the copper pin, so it works just fine. You can also turn the delrin to adjust the height of the pin depending on your atomizer.
As for the button, well, it's a mess. I was going to mod the crap out of it like everyone else in the thread, but I realized it was just going to be a lot of hassle with that glue in there. Probably the best (read: easiest) thing is to grab an upgraded button with a brass contact, no magnet, and no glue.

The few bucks will save you hair loss.
Once you get the button, you can just slip a drip tip o-ring on the pin to shorten the throw, and torch the spring a little to make it less stiff.
After doing all that, you're going to find yourself with a really solid, well built, very well performing mod. I've used mine exclusively since getting it, and it's rocking on an iGo-L.
