Future damascus Fairbairn-Sykes dagger

[Ariel Salaverria]

This is a custom order I forged back in February, but I just got to ground it last week.


Chainsaw chains and a flat 3/16" 5160 stock.

Using an electric welder, I welded the chains to the stock (note the cutting teeth)

I made a cannister with a pipe and I made a sandwich with the welded piece and two layers of 304 stainless steel, one on top and one on the bottom, to prevent welding against the pipe (so I can retrieve the ingot easily)

Once it welded properly, I took it off the pipe/cannister (no pics of that process, sorry)

You can see the welded piece on this group picture, though.

Preparation on a new capsule, with an identical pipe, but this time I cut it on the upper corners.

I placed a 2mm thickness asbestos paper as antiwelding barrier, as in this case, the SS 304 would be useless, as the bronze would weld with it.

Placing them on top of the asbestos paper.

Some borax on top.

Then I placed the 5160 stock and chainsaw ingot on top of that and I add more borax.

More brass plates.

WOW!! You could probably make a knife out of a dognut

Interesting concept there Stabber. Be sure to point that one out at the next S & A get-together! :D: Outstanding work as usual, Ariel!

[Fenlore]

that looks pretty damn good

[Lemmy]

That is so cool! Thanks for sharing. :-D

Ariel (http://www.jerzeedevil.com/forums/member.php?u=139),,

Great post.

That is the best tutorial progression on chain Damascus that I have ever seen.

Very Cool...:bow:

That shit is bananas. B. A. N. A. N. A. S. :faint: :dance:

[Kaxter]

Wow, really cool how that all happens. I had no idea all of that work went into making a blade. Cool stuff.

You doing any teaching? Cuz if you do, Where do I sign up!


Thats kewl two thumbs up!!

[Ariel Salaverria]

Some more info :)

Those brass pieces are cut outs from drums cymbals I repair.
If the drummer cracked it on the border, I cut a ring on the outside diameter to get rid of the cracked part, leaving a smaller diameter cymbal.


"how does the introduction of brass into the billet effect the final blade strength?"

It doesn't affect it at all, it's purely cosmetic, as the real steel for the blade got forged on the first canister at 1300C
The billet you see on this picture:
http://www.aescustomknives.com.ar/images2/arielstuff2_bigger.jpg

Is a fully welded/forged one. Think of this blade as a regular damascus from the chain, on where I left some superficial spots to show the links and then fill them with melted brass


Also, if anyone's wondering about tempering, instead of taking it to 850C and quenching it on oil (brass melts at that temperature), you can take it to 800C and quench it on warm water, with the same practical results.

In this particular case, I took it to 780C as I wanted it to be a little softer (about 55Rc) as this is a sticker. Of course the point and edges got a little more hard as they have less mass, but that's better for the knife too.

Thanks again for the comments!

Regards,

Ariel

PS: I can't do much teaching in my shop now as I barely fit in myself there, the last press took all the space I had left. Hopefully I'll be able to remodel my shop in the next few months to add some space there.
Plus I'm a little far away, you know :D

I do however, try to answer any questions anyone might have about what I do, so if you'd like to ask me something, please go ahead :)

Oh wow. Once again, very nicely done Ariel.

[Lazarus Long]

That is fucking awesome! Make me one!
