True story or legend about metal forging /blacksmithing

Hello,

Somebody told me the story that a hungarian blacksmith is forging a piece of metal until it starts to heat up that in on moment he lights his cigar with it ? He does it on public artisan markets to show his skills.
I was discussing the issue with some friends and the were laughing, saying that it is impossible.
I still believe in that story (but I´m the only one) and would like to know what you think or if somebody has tried it ?
I don´t have any idea about the size of the metal.

Greetings from Buenos Aires

Believe it my friend. The

Believe it my friend. The ancient Japanese smith used this technique to start their forges. It's really quite simple. Cold forging causes friction within the metal and thus generates heat. Try it on a small piece of stock and see for yourself.

Absolutely true, I'm sure.

Absolutely true. I've done it myself on a few occasions, to demonstrate that working metal moves the molecules, causing heating. You have to start with a piece of relatively small low-carbon steel bar, say 5/16" (8mm) and use a good-sized hammer. You draw a taper, flipping the piece every blow so you get the maximum movement and you can get it to a red heat. The odds are good that you'll split the end of the stock, but that doesn't matter for a quick demo.

The same principle is what allows me to heat 3" of the end of a bar and, using the power hammer, run that heat two feet up the bar. It just takes really good timing on flipping the bar between blows so you don't get it too far out of square.

Thanks so much !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hello Rich and Nathan,

Thanks so much. I was in a round with three others and all were looking at me , like I was making up stories. I got told the history and started to feel bad because I always thought it's true. But then I started doubting and thought well I figure out.
This will cost them something !!!!!

You made me happy today.Didn´t know that it is so easy.:):)

Thanks for your reply.

Make it cost them something.

This sounds like fun. If you have not yet showed your friends the proof yet, you just have to set up a bet.

metal forging story

I keep thinking about this story...
Metal warms up just going through a rolling mill...
how fast would someone have to be moving to bring the metal up to that kind of temperature?
I'd love to see this.

I don't think you can do it

I don't think you can do it with a rolling mill, Linda. For the same reason you can't do it with a hydraulic press - the metal is in contact with the die, rollers, etc, and loses too much heat to them. I can do it with a hand hammer, and I can run a heat with a power hammer, but I've never been able to do it with a press or rolling mill.

Doing it with a hand hammer is a LOT of exercise compressed into a very short period of time. You have to be delivering hammer blows as fast as you possibly can and flipping the metal 90 degrees with every blow. It takes me about 60 seconds to get a small rod up to sufficient heat to light my cigarette or start some paper on fire.

Your the Bomb Rich!

Sound to me that a Youtube video needs to be made of you lighting a cigar with forged steel rod. Think of the cigar endorsements you could be receiving. You could be flowing in residual cash and free cigars!

I can see it now.... Rich picks up his cigar and searches for a match...... seconds later he picks up rod and hammer and whails relentlessly on the rod until it glows. Lights his cigar and then sits back in his recliner with drink in hand...... Ahhhh!

Seriously.... It would make an interesting video.

That´s a good idea Fred

A video would be great. I was looking already but couldn´t find anything. And my friends still don´t believe it and said I have to show it. I said, I can´t do it anyway because of the leck of practise forging steel and bigger anvil.

fire from steel

That would be great. I would love to see it too. Definetly U-tube worthy.

yes you can...

I ran a (Scotchman)hydraulic punch machine for 6 years,and believe me the friction DOES get the metal hot enough. Especially if you're skilled at what you're doing and can go fast...If you didn't use oil it could light a cigar. Now I'm talking an 85 ton punch punching 1 inch thick steel...
