Case Bulldog Brass Liner Bent or Sprung?

Now starting to leave micro scratches on blade. Called Case they are afraid to dissassemble saying scale might crack. I thought about putting a wooden ruler between them clamping the scales near the bolsters and putting it in an oven.
Attempting to soften the brass a bit. Just letting it sit overnight for how ever long to reverse the bend might take years!

My guess is it was a tad to long when made and over the years sprung.
Any experienced ideas????

The one other thought was purchase a resin syringe system and get it between the liner and the scale.
Downside to that is once hardened and fail then the only option is dissassembly.

This is a rather nice Transition model with a clean full blade and nice tip. So......

It is what it is. Don't think much you can do to fix that except replacing the liner and it is probably not worth the trouble and expense. Enjoy it as is.
 
Looks like the liner is bent. If that was my knife I would mix up some 2 part epoxy and put it between the handle and liner and clamp it with needle nose Vice Grips. Immediately wipe off any excess epoxy that squeezes out.
IF it were my knife.
 
Never seen anything like it! :eek: It's as though the liner is under tension and buckled. Soon you might not be able to open or close it, a new variant on liner-lock :D:D

Markesharp's advice is very sound. Good luck :thumbup:
 
I actually gave the Case folks the all clear. I reasoned that they having experience and proper tools would be
Able to hit the pins from both sides and feel how it should be dissassembled. Better them than me......
But because there are no parts to replace should it crack. They won't do it.

I will prolly do the epoxy thing.
Is there no sense in trying the oven warming brass reform idea?
After it cooled back down and I removed the spacer I believe the brass would have "changed"
With a new memory.....
 
Agree. Tension. Must have been a bit to big. Any other time space appears is with say shrinkage of the stag if there is such a thing. But I've seen a bit of space in the past. This though is quite off the 'rails'..
 
Thanks Mark. I see you are a craftsman. Maker. I once fixed a striped door hing here in the house. Bonded the metal to the wood. So brass and stag...... Except there is really only going to be a very thin layer there. I think it may be tricky.
 
Mark knows his stuff, I'd clean thoroughly, HOT HOT water and if possible to insert something thin like a business/credit card to help clean any debris, then rinse again with Hot water, than thoroughly blow out area with compressed air. An option to the needle nose vise grip (as I'd be Leary to crack the covers) would be getting some wood wedges and insert in the well once the two part epoxy is filled into the gap.

Let sit for at least 24hrs, then hopefully she'll b good to go:thumbup:

Now as for Mark, go feed your new pup brother:D
 
I can add that I have inserted a wooden ruler. Nearly a perfect fit. But I noticed the scale at the bolster was under outward pressure. So just a little to tight. When it was sitting over night (hoped it would just be so easy!) I set it up in a hand
Wood clamp from the hardware store. Used to glue woods together. Has a pistol grip. Like a calking gun style.
Which concentrated the pressure in the right spot.
 
Yep. Wood wedges will be perfect. I put a roof on the house and have some pine shims left over some where!
 
If they spaced the holes too far apart for the pins it would make the brass buckle when it was assembled. Feeler gauges could work to get everything out from between the stag and brass.

Beware, I tried this once and the brass was stronger and just bent my jigged horn scale instead of straightening out like you'd expect.

I'd be concerned about that too. I have an older Schrade-Walden 25OT (folding hunter pattern) with a bent/warped brass liner between the two blades, tending to 'pinch' the secondary skinner blade a little bit. It's sort of amazing, as thin & flimsy as the brass looks, it still retains some STRONG temper in the bent position. All my attempts at gently straightening it were for naught; it immediately springs back to it's quirky alignment. It's not limiting functionality, but instead is just cosmetically imperfect. I've decided to leave it be.

Funny you mention that, mine's a "Folding Hunter" pattern too, though it was a RR kit. Mine is bent outward in the center. I figured that between gluing it to the scale and assembling the knife it would straighten but no, it's still bent even though I put the lockbar pin through it!

But it doesn't really impede the knife much, The frame drags on the tang which adds some friction for the first half of blade travel (won't snap closed) and the blade sits off center which is annoying, but the knife still locks up and cuts stuff just fine.

I wouldn't advise any kind of oven fix, it'll end in catastrophe. The Stag certainly won't like it and all the other brass and steel components could start acting up too!:barf::eek::D:D
 
I would agree. Not wanting to do that just Yet (oven). But with a wedge I would think that area of brass would react first.
But...... The sun shine was hot and long today. I jigged it up in a wood clamp wrapped in a wash cloth.
Shoved the wooden ruler between the liners. Let it bake out on the
Deck all day.
Let it cool to room temp.
Unjigged it. Wishfull thinking? Day 1 looks better.
Will continue in hot weather and see what happens.
I was sitting here when all of a sudden I heard what I believed to be a cracking/release type sound.
The jig was there where The sound came from. I thought geeze. Did the stag crack after all? Just now? This was hours later.
But it wasn't that. So I will repeat. To my eyes it looks straighter!
