Fogger V4 ?

[Steamer861]

So I got My fogger V4 today now I put it on my ohm meter to do a build and it shows resistance? 0.22
every thing is tight
It has a little copper screw on the bottom of the 510 It's the same set up as a Russian 91% with the bigger screw under a smaller adjustment screw (little copper screw) If I remove the copper screw and the o ring and put it back on my ohm meter it it's fine no resistance shows
anyone have this issue?

First... if you've not already done so, disassemble and thoroughly clean all parts. There tends to be a bit of machining lubricant on the threads.

Second, there is a small amount of resistivity in the 510 screw threads, if it's not fairly snugly threaded into the upper screw... in other words, the threaded surfaces need to have firmer contact.

I use small diameter silicone tubing, cutting off what ever length I need (as a substitute for a "stack" of o-rings), along with tiny, non-conductive fiber shim washers - to both space the screw and keep firm tension on the threads.

You can accomplish a similar result by using additional o-rings, or any other non-conductive material, to space and add tension to the screw.

State O' Flux Thanks for the post Lucky for Me I ordered 2 of them and the second one is Fine
It is kinda of puzzling were it could be making contact?? I took it rite apart and everything looks good? there are plastic insulators in there
that do not appear to be damaged I tighten it real tight and loosened it off a bit just to see
I know it's not rocket science it must be making contact in there some were I just don't know were
any buddy else have any suggestions??

I know it's not rocket science

True, it's not... but sometimes, even the simplest of things can baffle for a while... and require far more tinkering than they deserve. I'm sure you'll sort it... continuity ain't that hard. ;-)

Ok so I found the problem
the way the insulator setup is there is a plastic shim under the pin on the deck and a plastic O ring in the tube were the pin goes thru
when you unscrew the centre pin the contact above the plastic insulator is set in a hole with a plastic sleeve in it but nothing at the bottom
so when I tightened the centre pin it was pulling the contact down far enough to touch the bottom of the hole were the contact sits in
I put a small piece of an O ring in the bottom of the hole under the contact above the plastic gasget and it fixed it
I know it's a bit hard to understand my explanation guess I should of taken some pics
Bottom line it is not shorting any more and it WORKS!!
by the way first impressions of the Fogger V4 are all good I put a .85 build in it and it's Performing I really like the glass and the price was rite
