Another tutorial - Damascus from motorcicle chain, powder D2 and 5160

[ArielSalaverria]

This was a request from a knifemaker firnd of mine (Raul Carrizo). As he continues to make a knife, I'll update with more pictures.



Square section (40mm) pipe, modded to be the container for the steel.




I start placing motorcycle chain segments inside (8" long) with a flat piece of 5160 in the middle.





D2 scraps.




For each piece of chain, I add D2 scraps to fill in the spaces.














Closing the container.

Welding both halves together.





Placing it on the oven at 1300C.





Pressing it to weld the steels.








Container after welding the steel inside.








Pressing it to flatten the ingot into a flat piece (12" long, 2" width, 5/16" thickness)

How it looks after a rough grinding. You can see the chains, D2 (blue arrows) and 5160 (red arrows)














Thanks for looking!

Here's a little scalpel I've made from the piece I kept from myself.

What I did with the main part of that piece will come in the next posts

1" cutting edge. (1 1/2" from tip to handle)
5 3/4" overall length. 7/32" thickness.















Thanks for looking!

Here's what I did with my part of the damascus...

First I cutted it in half, and in the middle I placed a piece of some damascus I had already made (100 layers of 1030 and O1)

When I get orders for some special knives, I make 2-3 damascus ingots and I keep the best for that knife, and find what to use the rest for (or design a knife I think it would look nive with that pattern)




Then I got it on the oven at 700C




I added borax.




Then I placed it on the oven at 1300C and press it at full power.




Then I lended the camera to my daughter and she took of with some friends, so I couldn't take pictures of the grinding process. But you've seen that on other tutorials.

And this is how the roughly ground knife looks like (nothing special so far, right? )





Thanks for looking!

Now this is the ground and etched blade (just needs sharpening)

You can see all the different parts of the original metals there.

Since I'm a big fan of asymetrical damascus and random patterns, this blade was particulary interesting to find "hidden" random figures on it.

There are some obvious ones like the heart on the tip of the other side, and some that require some more interpretation.


All in all, this blade has motorcycle chain, D2 powder, 5150, O1 and 1030. Quite a mix!

Almost 9" from tip to end of bolster.

























Thanks for looking!

Really beautiful work.
I like to work with chainsaw.
But with D2, I never saw.. Its hard to weld, I think.
Always producing good work, and tutorials.
I like that kind of person that share his knowledge with others..
Again, congratulations..
Te parabenizo.. Buenasso G?ucho..

Gracias

And this another blade from that steel.
San mai with motorcycle chain, D2 powder and 5160 on the sides and a damascus made from O1 and 1030 as the core for the san mai.
This will probably get a mokume guard and some wood handles.

Blade: 4 1/8"
Edge: 3 3/4"
Width: almost 1"
Thickness: 5/32"
