I Forge Iron

An Information Seeker

Hi Everyone,

 

I'm Mitch, I come from a small town in Australia, and while I'm very interested in smithing I am physically unable to get my own forge or anything like that and am left with just reseaching the subject (which is fine I love researching things) and I've been watching and reading alot of resources, though I found that alot of them are lacking in a few details.

So I figured I'd try talking to some real black smiths to learn the things that wikis or youtube don't tell me.

I am also very interested in collecting swords (when I can afford them) which is another reason smithing appeals greatly to me.

One of the questions I did have involves casting blades.

You cast Copper and Tin with a clay mold to make a bronze blade, but I dont see anything like that with iron/steel. I am assuming that this is because liquifying the iron/steel would mean that the temperature would burn away the carbon and leave a weak blade behind. Would I be right in assuming this or am I way off?

Anyway I hope that you all dont mind me floating around asking questions.
 

Nice to meet you all.

most cast iron is very unsuitable for swords, much too brittle

 

you would forge a blade rather than cast it, it can also be done by material removal, you start with a piece of the right type of steel and grind it to shape or you heat it and hammer it to shape.

it depends on the final purpose and your skill set

You are way off; in Western Europe casting of steel only happened after the 1700's and so a lot of the sword days were over.  Combines with the fact that early casting methods and alloys meant that the cast item tended toward a very large grain size and inherently weak and so they would teem fairly smallish ingots and then forge them to reduce the grain size.

 

Now in central Asia 1000 years earlier they were casting steel but would cast steel, (and wootz steel) "pucks" and forge them out to get the necessary properties 

 

May I commend to your attention "Steelmaking before Bessemer, vol 1 Blister Steel and vol 2 Crucible Steel"  Also "Crucible Steel in Central Asia production, use and origins"  a thesis that I believe you can download here: http://discovery.ucl.ac.uk/1317704/

 

Nowadays you could find alloys and high tech methods that would allow casting of a decent blade after heat treat and it would only cost 3 to 5 times as much as producing one by other means....one-off castings of "exotic" alloys are not cheap!  There have been some very nice blades done by CNC machining---by people who actually know how a blade needs to be designed rather than by machinists who are clueless about swords  (weight and vibration nodes are usually the giveaway on if the person knows what they are doing!)

As for physical limitations:  I have taught people with thalidomide birth defects, nearly blind and in a wheelchair smithing.   What are your issues? We may have a way around them!---a one fire brick forge run off a plumbing propane torch will allow small work to be done on a tabletop basis! (including small blade work)
