svd telescope tube getting really hot?

[benearl1]

So I've had my svd for about a month and its working great except one thing thats bothering me.. its authentic I got it with the scratch code and put it in and it checked out.. but recently I've noticed my telescoping tube part will heat up pretty hot in a pin point location ( not the whole tube ). Its hot enough that I have to lift my finger off that spot.. it takes about 5 seconds of firing after 2 or 3 chain vales for this to happen.

I'm using aw imr 18650s 2000 mah batteries and they both cause this. The tube cools down really fast and the batteries feel a little warm not concerning at all but they might cool down just as quick as the tube?. I'm using a kayfun up top 1.4 ohm microcoil n cotton build.. no shorts or hot legs perfect glow from the inside going out. Great vape at 11.5 watts so I dont think its the atty.. but could the heat from the coil and connection be transferring down to the Tele tube on that certain spot? It seems more like the battery would be heating up around that area but its only a little warm when I take it out right after..

Any input would be appreciated!

It shouldn't be getting hot / warm at any one spot. But what spot?

If I hit mine hard and long enough, it heats up pretty good at the top near the connection, but the rest of the SVD is fine. I agree with DavidOck, a more precise location as to where it's heating up would be helpful.

Good point, Retired1. And that kind of heat transfer from the coil is typical, especially at higher wattage settings. But will usually be around the entire circumference, not a pin point. Although it might be a bit warmer near the spot where the neg coil leg comes through...

The spot is about an inch and a half up from the battery cap on the actual tube you twist to telescope in or out.

That would put it at about the threads on the main tube...

Have you put any thread compound on it? I.e. NoAlox or similar conductive grease? (A little goes a long way!)

A hot spot there suggests that you're only getting a good connection at that point, so all the current goes through there. While I never had the issue with mine, it's a possibility.... so maybe take it apart and make sure all the threads are at least clean, inside and out. And make sure it's snug when put back together. Not wrench tight, but shouldn't have any wobble.

That might be it.. looking at it my threads are dirty looking and squeaky as well.. ill clean em up, use a conductive grease, and see what happens

Good luck, and keep us posted!
