I wasn't discounting that at all fairmana. It was simply a quick post over coffee before I got ready for work. Didn't mean to poopoo it. It wasn't a comprehensive well thought out plan just a quick post.. Me I've not had any issue with 510 leaking myself, and it's regularly wet or flooded. Don't take any offence, It would definately be part of a comprehensive upgrade modification. I think the 510 pin leak is more of a hit and miss depending on the condition of it when it leaves the factory...
I like my oddy flush mounted, it's center pin is adjustable. When its flush to the 510 it does restrict air flow. That's why I added deeper channels to the v3 510 for better air flow on flush mount 510 devices.
No worries Jeremy.
I wish we could be sure that both of those leaking V3's came with a cracked 510 from the factory, but both V3's had been used for at least a month, so its entirely possible that the crack occurred during that time frame. Maybe someone who reads this thread will buy one in the near future and will find a crack right out of the box and let us know. It just seems prudent to assume the worst case scenario and not have to worry about it later.
By the way, just out of curiosity, what did you use to deepen the channels on your 510? A file or a Dremmel cutting wheel? How did it turn out?
Lastly, that mod I was talking about before with the spring loaded center pin is the Tesla. I found a
video review that shows the top pretty good at the 5 minute mark. Keep listening for about 30 seconds after the image goes back to the reviewer to hear some good info about it. I don't know if any other mods have a spring-loaded center pin. I would sure love to have that center pin on my V3's.
