Hey gents, it was about this time last year that I did the work-in-progress thread on the damascus camp knife. It's taken me until now to recuperate enough to give a WIP thread another go.

I'll be making a bowie with a laminated blade, damascus fittings and a micarta handle. The knife will also be a take-down.

I've been making laminated stainless / carbon blades for the last few years, and several people have asked how I get the stainless and the carbon to weld together, and a few people have even made some nice finished blades. Bill Burke, Bill Wiggins and Daniel Warren are three makers who come to mind who've made blades based at least in part on what I've learned. I thought I'd actually show some photos of how it's done for the rest of you. Though you may think it's hard, you'll see it's a lot simpler than you might have thought...

Here, three pieces of steel, (two 416 stainless and one 52100) are cleaned.

Some Loctite Professional super glue (not the civilian stuff, the Professional grade) is applied to each piece.


dv003sm.jpg

The pieces are clamped and left for at least 48 hours. If left for less than this, the molecular diffusion will not adequately take place.

After the diffusion is complete, the bar is ground down and etched to see the successfully welded core.
 
Is this a joke thread, or are you skipping steps? :confused:
 
This will be really interesting.

I picked up a Darkside and was interested in the construction. If you look real close at the spine it's shiny/dark/light/core/light/dark/shiny.

There's a distinct layer between the outside and the core. I was wondering what the properties of the layer were and what caused it.

I think the magician just pulled back the curtain. Surprise! :D

Golly Gee!!!! Burt, why did you have to change brands of super glue??? Does this mean i have to buy all new glue..... And to think i have been wasting my time with two c-clamps when one spring clamp will do. And you told me 72 hrs. at the very least. Mr. Foster, I intend to get even with you for this!!
 
Ok, I guess you guys are right. Larrin was the first to call me on my super glue technique. Just having a little fun.

Here's the actual start of the process....


dv005sm.jpg

Here are two bars of steel. 416 stainless and 52100. I use round bars for a lot of things, mostly because I can use it to make a lot of different sizes.

Here's my goofy forge. Last time I built a forge, I thought the venturi burners would be the way to go. They worked well for a while, but as they deteriorated, they lost efficiency, so I added one, then two burners screwed right into the top of the burners. I'm going back to blowers, but I haven't gotten around to rebuilding the forge. Just FYI, the small forge on the right is a Len Landrum 2-brick forge that's super slick for regular non-welding type forging.

Heating up the stainless...


dv008sm.jpg

Flattening it under the power hammer. You can get some really cool photos with steel this hot.


dv009sm.jpg

Here are the two pieces of stainless, about 1.5" wide and 5/16" thick.

Cutting the bars to length.
 
it looks way easier and cheaper to use super glue.
 
So now .. what am I going to do with the superglued steels :D
I just glued them for about 11 hours! Should I wait for another 37 hours more :o
Kindly advice me, Burt :confused:

mohd.
