I often like to do personal mods to knives I purchase. However I have a chronic problem when reassembling liner-locks, which is that I can't get the blade to center when closed; it gets pushed by the lock up against the opposite liner. How the heck do you guys assemble your liner-locks so that the blade is centered when closed? I looked at the tutorials but didn't see anything that addressed this issue? Any help greatly appreciated!!!
 
some use a larger washer on the non lock side (not thicker mind you)
the trick really is getting the pivot to pivot hole a good fit tyhe more slop the more the blade can cant to the side when closed
 
The biggest keys are Pivot/Hole fit, flatness/parrallelism of liners, and thrust washer diameter.
Also, if the pivot hole is at all sloppy, the liners can be assembled so that they don't truly line up, causing the problem.

Picture one liner being just slightly forward of the other liner on assembly.
This makes the pivot on an angle other than perpendicular to the liner, and pushes the blade over to the liner side that is forward.
 
Fishface: Try assembling the knife, and tighten the pivot screw almost snug. Back off all the handle screws, then snug down the pivot firmly. tighten all the handle screws, then back off the pivot screw until the blade can pivot freely.
