Star Trek: The Next Generation
Williams, 1993The lockdown bar on my STTNG rocks back and forth like it is pivoting in the middle. I've tightened the 2 brass screws on the top but the problem still persists. It's like the slots that receive the bar are too wide or the arms aren't thick enough. Is there another way to adjust this that I'm missing?
You want to loosen the screws to extend them out, rather than tighten them.
Extending them out pushes them against the lockbar, which should help stabilize it. (not for WPC style lockbars)
The other issue might be that you have an early Williams lockbar installed, rather than a later WPC lockbar, although I haven't tried a early lockbar in a WPC game to see how closely it actually matches (or doesn't match).
Quoted from ForceFlow:You want to loosen the screws to extend them out, rather than tighten them.
Extending them out pushes them against the lockbar receiver, which should help stabilize the lockbar.
Really?! I thought it only tightened the lock mechanism when they were turned in. I'll have to try your idea since I have a couple of loose bars that won't behave.

Excellent. I'll try that one tonight. Seems counter-intuitive on their end, but I will definitely give it a shot. Did they make different types on lockdown bars for Williams widebodies?

Oh, that's right--I forgot that STTNG was a widebody 
There were a few early williams widebodies, but the chances of one of those ending up on a WPC game are probably fairly low.

It makes sense actually because they are brass so as to protect the lockdown bar's underside. I would have never tried this, but I will tonight!

Yep. I totally get it now. Hopefully this will work for both of us!

Sorry, but this isn't correct.
The screws are to adjust the receiver bar which locks to the tabs on the lock bar. The end of the brass screws push down the receiver. Check the photo attached.
Tightening the screws (clockwise) pushes down the receiver, making the lock lever harder to move but pulls down the lock bar tighter against the glass and cabinet trim.
Loosening the screws (counterclockwise) loosens the receiver, making the lock lever easier to move but doesn't pull down so hard against the glass and cabinet.
Sometimes you need to muck around for ages to get it right.

You're right, I was just about to post a correction--some Gottlieb lockbars are like what I described earlier, WPC lockbars use a different mechanism for adjustment.

Is this the only method of adjustment? I tightened them to where it was rather difficult to lock the bar in place, so I know it was on there tight. I was still able to get a good amount of wiggle, albeit with a little more force.

Maybe go and edit your post.

I have a Bally Atlantis. I had to buy a replacement lockbar because the old one was old, beat up, and had weld marks on the top. The brand new one is exactly the same but it won’t lock in. How does the locking mechanism work? How do I adjust it? Thank you.
This is the one and the site that I bought it from. This was the best deal that I could find. It is 100% complete and has the foam pad on it. https://virtuapin.net/index.php?main_page=product_info&cPath=3&products_id=63&gclid=EAIaIQobChMIi4WUoNjq7QIVrFPVCh3X5gb-EAQYASABEgJx9_D_BwE
