Campagnolo pista hub lockring
This is my first Campy track hub, while I was assembling the cog I noticed the lockring didn't thread all the way, cog and lockring are ape force tightened, I was going to get a little spin and mash up a hill but I was a little worried about stripping it.
Is it just a extra thick lockring so I have extra threads and nothing else?
Lockring seems like a Miche.

Those Surly cogs are 7.4mm at the base; you might want to go with something thinner for that hub. Alternately, you can try a Surly lockring:
"We redesigned our lockring by widening it to 5.5mm, which added 38% more threading than our previous lockring. The added thread engagement will help secure the cog and lessen chances of stripping threads on the hub. Notice the small lip on the lockring. In some cases (when using ’05 Surly cogs on Surlyhubs, for example), a cog will overhang the lockring threads of the hub more than 1.5mm. The lockring should then be installed with the lip facing the cog. This increases the lockring thread engagement by 1.5mm vs. using a non-lipped lockring. When the cog overhangs the lockring thread sless than 1.5mm, the lip should face away from the cog...toward the outside of the hub."
EDIT: Never mind the lockring. I just read that they don't fit Campy or Phil Wood hubs.

Thanks for the response, the cog is brand X, cheap stuff from chain reaction.
So the cog may be too wide, any recommended sprockets for campy hubs? The only one that seems to fit in perfectly is a Campagnolo cog, obviously.

Maybe Euro-Asia or Formula, but I know thread compatibility is an issue, so shop carefully. Maybe see if Sheldon Brown gas anything to say on the subject.

It seems wrong, but I've been using a Dura-Ace cog on a Campy hub with no problems.
Just make sure you use a Campy or Phil Wood lockring.

I've used Cobra and TDC sprockets on Campagnolo track hubs without problems. Here's a Cobra sprocket on a Campagnolo track hub:

Have you tried undoing your work yet? If you haven't - I think you should. I'm going to come at this from a different angle than some other posters. I hate getting wordy but may have to, to make my point so please hear me out.
Everybody is talking about your cog. Cog threading is pretty standardized so I do not think that is the problem. It is the lockring threading - IIRC there actually are several different lockring threading standards that I am not going to look up now but anybody here can find them easily. But I do recall that it boils down to the biggie being English vs Campagnolo. There is a miniscule difference, but it is a difference and I once heard that St Sheldon once said something along the lines that while ISO, English and Italian are all semi-interchangeable, it is not guaranteed to work every time.
So I propose that your problem is that you
a likely Asian made Brand X Lockring onto a Campagnolo Track Hub and in your case, it did not work out for you. I suggest you re-start and think about what you are doing.
That wasn't so bad was it? Well good luck...

Yeah, the lockring was my main concern, but I just tried my miche cog, with Italian threading, it didn't thread all the way, but with a 16T Campagnolo sprocket, it leaves enough thread to fully engage.
I searched a little bit more about this problem and thtePhil Wood hubs have the same issue with some brands of cogs that make them a little more wide.

I got a Miche 18T single piece cog and lock ring on my Gipiemme hub with italian threads. Great quality stuff for very cheap.

Talking about lockrings, I wish more manufacturers used the bottom bracket style like Ridea uses, is so easy to apply force with a bottom bracket tool than the normal lockring style.

OMG you are the real deal, that was it haha, I guess I was too hipped for riding the wheelset that I didn't saw the "spacer", looks like a bottom bracket ring, my guess is that the previous owner wanted a straight chain line? Here are some pics, please don't judge me haha.
oh hi! you can guess my face when i saw this -_-
Fixed it, would be nice to use an Italian threat cog but the English threaded ones work too.
