I Forge Iron

Japanese hammer


Davor

Recommended Posts

Few weeks ago I came across an article, on the web, about useful types of iron in the blacksmiths shop and of course what they can be used for. And it said that a railroad track can be used for a hammer. Well I have a piece of track laying around, not from a train track but smaller. So why a Japanese hammer, well it seemed as the simplest hammer to create, and it is my first hammer project. I cut the top of the track with an angle grinder and drilled the hole, then I tapered the whole thing a bit and drifted the hole. Simple enough.

Hi Davor,

 

Nice use for a piece of junk steel. I just have a couple of questions:

 

Have you tried to use it yet? Doesn't it leave hammer marks in the steel? I can't see in the pictures is it crowned or not.

What diameter was the hole you drilled? And the final hole, is it about 2 cm in diameter?

 

Thanks in advance for the answers. 

 

Greetings

I haven’t used it yet, hope to find some time tomorrow. I’m not sure what you mean by crowned, the striking end has the biggest diameter. I drilled a 12mm hole and drifted it to 21 mm. I would like it to be a bit larger but I don’t have a bigger punch.

Thanks for the info.

 

By crowned I meant that the face of the hammer usually gets some grinding on the edges. This produces a bit rounded edge surface and thus you can better avoid hammermarks. Here is a picture which shows it well.

For bigger punches I use sway bars or halfshafts found on scrapyards. 30 mm dia is quite common. Just needs to hit it hard  :)

 

Tell us how did the hammer work after you tried it! Happy hammering!

Pretty good looking hammer Davor. Have you heat treated it? I don't know about RR rail in your part of the world but in America it's high carbon, 1085 +/- and if you don't draw a good enough temper it can chip dangerously. At full hardness it can shatter like a ceramic cup.

 

Crowning is putting a slight dome in the hammer face and grinding a radius in the edges is called "radiusing the edges". Radiusing the edges is more important than a crown as it not only helps keep from marring the work but relieves the edges so they don't chip as easily.

 

You done good Bro Keep it up.

Well now I know what crowned is I can say no it is not crowned, but it will be. Now when I think about it, it is pretty common sense. :huh: :P

 

I didn’t heat treat it, I’ve just let it cool down when I pulled it out of the fire (no quenching or anything like that). I was worried it might chip in use, but I didn’t have the time to use it yet.

The hammer works fine, well to be honest it worked fine till the head didn't break of the top of the handle. I guess that a 21 mm is not big enough for the handle. :huh:  Ill drift it some more, I just have to find or make a bigger punch/drift. It does take a bit of getting used to, kind of a strange feeling having such a long hammerhead.
