Hinderer question

I just acquired my first Hinderer, a XM 18 3.5 and it came with an extra scale as well as skiff bearings to be installed.

I've never disassembled a knife before so this is a first. Everything went fairly smooth but when I got it all back together I noticed what sounded like a rattle when I shook the knife. Took it apart again and reassembled, same thing. Finally figured out the light rattle noise is two of the three metal spacer things that sit between male and female handle screws, the round things. Anyway the two closer to the blade are spinning freely inside the handle. The back one doesn't seem to be doing it.

I've only had this knife for a few days and can't recall if those spacers spun before I took it apart and if it made that slight rattle before. So now I'm questioning if this is normal and I never noticed or if there is something that's not quite right. Functionally the knife is fantastic with the new bearings and I love the new scale, just want to double check if something is off with my install.


Thanks for any thoughts!

When properly assembled the standoffs should be snug, no rattle. Sounds like maybe your handle screws aren't fully tightened.



That's kinda what I'm thinking, but I can't seem to get them any tighter. I've put about as much torque as I dare.

Wondering if something internally isn't lined up quite right and not allowing full compression when the screws are tightened but I just can't see where that could be.

Maybe I'll try tearing it apart one more time
 
Something is not right. Post some photos of the knife, scale and Skiff bearings, maybe we can get it sorted.


I'll see what I can do, but the hard part is that I can't see anything at all to actually take a picture of. The entire knife looks right except those slightly loose spacers.

When I tear it down again I'll see what I can do
 
Does the stop pin sit properly ?

Anyways, photos will help us ....
 
The stop pin is the smaller pin that sits just about the pivot screw, ya?

Right. When you put the liner one, it's a bit of a Pita .... I first put it on pivot and stop pin, then I put the liner on the stand-offs/female nuts.

From the other side, before assembly, I put the nuts into the frame (lock-side), and glue some scotch tape over the nuts so they hold still when you put the standoffs on.

1 - Pivot into lock side
2 - Nuts into lock side
3 - Scotch tape over nuts
4 - lockside on table
5 - stand-offs on nuts
6 - bearings, blade, stop pin
7 - then comes the liner, should sit snug on standoffs/blade/stop-pin
8 - then you put scale on, and screws, start with scale screws (loose), do pivot last
9 - put some folded businesscard between liner and blade, to help center
10 - tighten scale screws.
11 - fine tune pivot

Just recalling what I usually do ...

Very helpful, thank you!
 
Got it!

Started to take it back apart when I noticed that two of the nuts slid in from the lock side were not fully seated and didn't sit flush. Undid those screws, pushed the nuts in till flush, and she tightened up rock solid.

Thanks for all the helpful responses all. Much appreciated. Glad to get that sorted. Good learning experience for my first attempt.
