Detent Help

So, recently I learned how to anodize and started customizing my knives just a bit. I acquired a Vero Synapse XL, and thought it would look great if the bolsters/liners were ano’d. I ended up using the torch for one scale, and the 9Vs for the other.

Unfortunately during heat anodizing I lost my detent ball (probably to expansion and contraction, which I should’ve foreseen). I found it, popped it back in, and now the once-amazing detent is way too light.

I tried bending the lockbar in a bit, but it didn’t do much. I think during removal and replacement of the ceramic bearing, I may have altered the depth or otherwise messed with how the bearing is supposed to sit.

Anyone ever dealt with this before? Advice on what I should try/do/Google Search?
 
It does sound that way. Can you access the ball from the rear (i.e., hole for ball goes all the way through)? Assuming so, I'd try pushing it back out a bit.
 
This is one of those things where if you made a mistake and can’t push out the detent to replace with a bigger one, or replace it with a rod you shape to size, you are stuck with what you have.
 
Can you post some pictures?

If there’s no pin hole on the backside to pop the ball out, you have two options. Take a small bit and drill a hole and pop the ball out. Or reheat the area and hope for the same results as the first time that the ball pops out.
 
I’m going to disassemble the knife again sometime today and when I do pics will come up. I’m going to try the reheat method, because the Synapse XL isn’t exactly a cheap knife to drill a hole in. 😂
 
Are you sure you can’t just remove the lockbar insert and work from there. All pictures Im seeing show the lockbar houses the detent ball.
 
So, the reheat successfully got the ball loose again, but I cannot get it to stay at the position it needs to. It had some sort of glue on the ball that held it in place…

Yeah, removing the insert is definitely on the list before I try and get professional help, but the issue is now how to get the ball to stay where it needs to be. Superglue failed immediately, but it was worth a shot.

It wasn't glue, it was a press fit...the metal is deformed from pressing it in too far now. You need to decrease the hole diameter at the surface, peening or staking near the edges of the hole with a center punch will do it easily if you know what you're doing.

I know what I’m doing this evening.

I certainly do not know what I’m doing, but I plan to learn. Or figure out I need someone who does have the skills.

Thanks!
