Fat daddy v4 510 question

[Panther1911]

I decided to try and make a mod.

I ordered some v4 510 connections from fat daddy vapes.

I can unscrew the brass positive "assembly" from the insulator.

How do i get the positive pin out from it so i can solder to it?

I haven't used the v4, but a lot of v3s. Yes, you can disassemble the "core" for soldering. That's a must of course.

I am just unclear how to disassemble the core on the v4

mine looks close to this

Hmmm. Different construction. That looks okay to solder. No insulator material on the inside, and the red o-rings are rated for high temps.

Do you think I would have any issues with the spring on the inside?

No. This redesign appears to address the problem of excess solder impeding the movement of the center pin. I've run into that before. It's safe to solder IMO.

Thank you!

@Panther1911 How did this work and how are you liking the v4?

i honestly have not tried yet, when i got it in my head, i was in "go-go-go" mode and was trying to find stuff that weekend, but when i had to break down and order most if it online and wait for it, i started putting all the stuff that come in into a box, and once it all came in, i kinda lost motivation to work on it, plus the fact that its been mostly to cold to work in the garage here. now that its warming up, i may get some more motivation

I'm trying this now on the IPV3. Threads went wonky so drilled out the old 510 and trying this FDV 510 v4. I'll post once I have completed.

I took off the o-ring and used a small torch. Worked perfect for the soldering but when I put it together and tested the spring of the pin, the bottom portion of the pin popped off. Its a compression fitting so the heat loosened it and there is no way to reattach unless using an epoxy but given the small surface area that cap grabs on too I can't see it lasting. Lesson learned, DO NOT use a torch on the v4 FVD pin for soldering. Ordering a replacement and will use a soldering iron on next attempt.
