Blade centering on Oso Sweet and other speedsafe knives.

Recently I disassembled an Oso sweet for cleaning and re-lubing. Now when reassembled the blade is offcenter, it is almost touching the non-locking liner. Before it was properly centered.

I have dissasembled many knives (only manual opening ones) an never had this problem. I checked all the parts and they are straight and there is no wear either.

I read on a previous thread about a method for centering, but the diagram picture is gone: http://www.bladeforums.com/forums/showthread.php/676100-Quick-Kershaw-Mafia-Question/page2

Any one knows what the method is? According to the threads it involves an specific sequence for tightening the handle screws.


PS: For lube I am using Superlube grease, which is the closest I could find to the original factory grease on the pivot and torsion bar.
 
The procedure involves using some folded paper as a spacer between the blade and the liner that it is close to, then tightening the body screws first and the pivot screw after. Really, it's just a matter of getting the two halves of the knife aligned correctly. Hopefully, someone still has the the diagram; it's so much easier to understand with a picture or drawing of some kind.
 
I had been looking for that diagram myself as well, but found the wedge of paper to work well. Using it to push the blade to lock side, I'd tighten each body screw down starting with the one farthest from the pivot point, then the pivot itself. It works every time for me.

doesnt work on my 560 :(
 
Sorry about the bad link, fixed it.

Here's the whole post from the Kershawholics group.

Blades can be centered by loosening the handles and shifting them slightly in relation to each other on the long axis. This in turn changes the angle of the pivot's axis. A tiny movement of the handles can move the tip of the blade quite a bit.

Reverse directions to get the pivot to shift the other way.

So you use folded paper to push the blade to the other side and then after you tighten the screws it stays that way?
 
Yep, pretty much. Take a look at my Cryo video, skip to about 13:28:
