It appears my tailstock is missing something. The tang of my love center (drill chuck too) has nothing to grab on to. Not super familiar with tailstocks, was wondering if someone could post a pick of what it's supposed to look like inside

The one on my G0602 uses friction. There is nothing inside other than the screw itself. The MT3 taper doesn't start to grab until about the 20-25mm mark on the quill. Anything under, the screw pushes it out for removal.
It won't engage at any point tony, thanks for the reply though

There is nothing missing from your tailstock. There is not supposed to be anything for the "tang" "to grab onto". You are putting a male tapered thing into a female tapered thing. Friction alone is MORE than enough to hold it, and prevent it from turning.

Then what's the purpose of the tang? Thanks ray

I have no clue. Probably something from the very distant past, as MT tapers are used for all kinds of things, and have been for over 150 years. I suspect the tang was originally used to remove the tool from the taper by inserting a cross-wedge through a slot in the holder, and whacking it with a hammer. That is not only impossible, but totally unnecessary in a lathe tailstock.
I have NEVER seen a lathe tailstock with anything to grab the tang.

I have an old Clarke drill press that has a slot in the back of it's quill for grabbing a taper like that. But in this case, friction alone does the job on the 0602.
Turn the tailstock out to about 30ish mm (1"+) and slap it in... it should grab and get tighter with more pressure applied against the work.
btw, I'd try to clean up the rust/corrosion on the inside of yours... that could be an issue as to why it isn't grabbing.
I slap mine in and it holds tight unless it binds up on a deep bore or I roll it back too far and it disengages on the quill screw.
I appreciate the replies, thanks guys

That rust looks bad from here. Clean it out. And forget about the tang.

Like other guys have said, the tang is meant for removal. It doesn't actually drive anything, the taper its self is what locks the tool in place.
Your tailstock looks pretty rusty, you should definitely polish that up as best as you can otherwise it might spin on you.
This is how much the tang does to drive a tool when the morse taper slips lol
My tailstock taper does have a drive for a tang but some people say it's not to drive the tool but also I can eject tools without the tang so unless it's there for a drive I have no clue either. But in you case it looked like a damaged taper and a lot of rust. So maybe that is why it won't stick?
The reason I thought it was held by the tang is because the only lathe I've operated had a tailstock in which the center or chuck would only fit in one way (the tang fit into a groove of some kind) so I assumed the tang was what made the center or chuck stay stationary.
