and so it begins... O1/L6 3-bar Han jian with Wu.


Recommended Posts

Hello Everyone,

I am back into Chinese sword mode, thanks to inspiration and many, many facebook messages from my friend Scott Roush.

 

I started over from zero with this project. I abandoned a previous blade that was w2 and 15n20, with which I attempted a double shangxue.

 

Going with more shock resistance and no hamon on this one. Prettier pattern welding, too.

 

3 bars, the edge bars are about 2:1 O1 to L6 by mass, the center bar is about 2:1 L6.

 

23" blade length, I will extend the tang to make it 11".

 

Of course, about a zillion things could go wrong, but I am going to share, good or bad.

 

I need the encouragement, and hints along the way.

 

comments are welcomed, as always.

after first welds. Taking it slow. Just cutting in half and stacking to get a more layers.

Using the twist-o-matic. A word about O1 - I crumbled the first twist. It went, "red short." This little forge gets rocket hot at the hot spot (of course). I had to turn it down to get the twists to work right. With W2/15N20 I could just let it rip. This is why everything after twisting only shows 3 bars. I saved a lot of the bar that fried, but I am going to use what I saved to make a knife or two. I have plenty of steel for a sword from just the 3 bars.

very careful with final welds, so I milled the mating surfaces flat and square.

23" blade, with 8" of tang that I will weld or braze an extension onto. It isn't traditional (they used a peg like the Japanese) but I am going to peen the end of the tang.

still need to do the, "fish mouth." If it fails, I will get more length by tapering and just leave it alone.

you can't really see it, but the edge bars have a different number of layers than the center bar. 18 in the center, 10 on the edges.

Ricky,

just got back. What are you doing online?

Wesley, I gave up on the double-hamon (shanguxue) blade because I just couldn't keep it straight. This blade, believe it or not, is the simpler blade. I think that maybe I could have done random laminate at high level for the edge, but then I needed to do at least 2 center bars. So, that will be what I do next time.

Thanks for asking, guys. However, there won't be any progress for a month or two.

 

I AM MOVING TO A NEW HOME, AND SETTING UP A NEW SHOP! Finally, a dedicated shop separate from the house. But, this means no work on the sword for some time.

Good luck with the move ! after getting heavy equipment this last year, (2 lathes, milling machine, power hammer, forging press, shaper, screw press) ... i dont even want to THINK about moving for a very long time =) I'll probably have to seriously hire a rigger and moving company to move my machines now

Justin - I have hired a rigger to get my stuff across town. Not even that far, really. But, the kiln with the retort, the milling machine, and the hydraulic press... I can't put those on a moving truck myself.

 

It isn't too bad, not really any more expensive than hiring regular movers.
