Question about using a spring in my top cap?

[Tony Da Taiga]

Hey there. I been having some irritating troubles lately with my adjustable center pin screwing/unscrewing itself.... I was wondering if using a spring (that I took out of the firing pin of an old mod) and using that to keep the center pin from getting loose was a safe idea or not.

Here are a couple pictures of what I am trying to do.

It's a perfect fit but I was wondering if it would cause a short or be potentially dangerous to do. I'm not the brightest when it comes to currents and electricity and stuff. Any advice would be greatly appreciated. Thank you!


Oh! And it is a Panzer Black Hawk clone that I have.

The spring can always slip sideways and create a short between the positive 510 and the negative female thread. If you do this, be careful. I'd just put in a small rubber o-ring under the screw to keep it from unscrewing.

Ah! Never thought of using an O ring. Thanks a lot!

I'd look for a spring that fits closer to the diameter of the screw if you go that route, that helps eliminate the amount it can shift and cause a short. With that said, I had a very similar setup as the one you're describing (almost identical) and the spring worked like a champ for me, never slipped at all.

This is a VERY common fix used for this very issue. PRO TIP: When you get rid of an atomiser or mod....keep the accessories...especially the o-rings. When you bin an unwanted drip tip (like the pointless lung collapsing ones that come with Kayfuns), KEEP the o-rings.

Thanks for the tips! So far the O-Ring thing is holding pretty well. Just need to hold out till payday... Time to retire this mod and buy a new one :3
