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

18 posts in this topic

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.

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)

Thank you for the comments :)

 

I'm very proud of that press, I've designed and build it myself!

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 :D

 

1" cutting edge. (1 1/2" from tip to handle)

5 3/4" overall length. 7/32" thickness.

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.

And this another blade is a 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"

Having never made damascus I didn't know it could be done that way. I really like the shot of the integral bolster. Nice pattern . Jim

After seeing this post a few days ago I realized I was sitting on a gold mine!!! I work at the local motorbike shop where we're constantly changing sprockets, bearings AND chains. Just got my hands on on a serious chain today - thrown out - and have it soaking overnight in solvent. Going to wire wheel off the bits of rust and put it aside for whe the time comes..............now to watch out for more steel supplies....muah ha ha

You'll have to take that up with Señor Salaverria. His signature link still works, but he has not been on the forums since 2011. That's too bad, he does some crazy stuff that shouldn't work but somehow does.

 

Many of these older topics have broken image links due to the original poster having moved, deleted, or lost track of whatever off-site hosting service they used. In this case I believe the original pics for this thread are now being hosted here: http://www.aescustomknives.com/docs/knifemaking19.htm
