Subject says it all really - I've done blacksmithing for three years now and started up my hobby on little more than £50 - no anvil and no forge.

I thought maybe this thread would be nice because I'm guessing most of us don't have an old anvil lying around and don't fancy forking $600 to buy one, on top of a $300 forge.

In this thread, should enough people care, I'm going to go through making a 'forge' out of nothing much at all. Making charcoal and bellows. Making an 'anvil' and if we make it that far I'll share some tips on heat treating and all that bull. Maybe even go on to what to look for in buying your first anvil...

So basically "Shit I wish people told me 5 years ago."

I'd like it if people could say if they're watching the thread, so I know when to stop posting. Thanks.

When building your forge it's great if you can start with a BBQ, if not a could of bricks laid out across the floor or a table should do fine for your base.

Once you have your base sorted you're going to want to, using normal house bricks, section off three sides keeping it the same size as what you plan of heating up, if that makes sense. So if you wanted to heat up a metal pole to make a knife you'd only want a very narrow, about 4 inches wide, gap between the walls of brick.

Rule of thumb, make the gap about twice as wide as what you plan on forging.

There you have your self a very simple yet massively effective forge.
Next post I'll talk about what to burn and how to heat it up enough.

For fuel you want to use Charcoal.
Brickettes are total shit and will spit at you and shit, so keep away from them.

Coal works fine but takes much longer to get going.

If you want to make your own charcoal it's easy enough. Get a tin of quality street or something and stab a few holes on the top. chock it full of wood, as much as possible, and leave it in a fire - BBQ will do fine, or, as I do, make a fire separate to your 'forge' and make charcoal as you burn it.

So you have your 'forge' and your fuel.
Now you need some 'bellows'.

Gonna have to reach deep for a second here in to the wallet.
$5, get yourself a hair dryer, $2, a copper pipe (1 m) and 2$ a real of duct tape.
See where this is going?

Drill some holes, about 20, in the bottom of the pipe, small ones; think tooth picks, and make the same end flat with no gap, or as little as possible. This can be done easily enough buy heating it up and hammering lightly on some concrete or something. Attach the other end to the hair dryer using duct tape. and there you have it, a 'bellow'.

Bury the pipe deep in the charcoal and only start blowing once the fire is going well.
when there's a good stock of glowing shit in the fire you're good to stick your steal in.

There are two paths you can choose here... One is Much, much, much better than the other.

Railroad rail. If you can get your hands on this shit you're sorted. It's hard as balls and doesn't require any work. beat away.

If you can't get your hands on any, don't panic... Well, sulk a bit, but there is hope.

Get your hands on some steal, think I beams, and throw that in your fire after attaching a long chain to it(we'll use this chain to get it back out). Heat it up for what will most likely be $20 of charcoal and about 2 hours. Once it's glowing, give it a few more minuets and, using a magnet on a stick, check to see if it's magnetic. If it's lost it's magnetism - you're good to go on to the next paragraph. If not, keep heating, keep bellowing. I know this part is a wanker.

Get yourself a bucket and fill it with cooking oil - this is pricey but will last years and you'll need it later anyway. Using the chain (being careful not to burn yourself) lift it up and dunk it into the oil. There will be flames. Wait about a minuet and then pull it out. Hopefully it's still in once piece.

At this point you have to use your oven - another wanker of a step. - throw your I beam in there on Gas mark 5 (like 220 degrees) and leave it there for hours, I'm thinking about 4 or 5.
Turn the over off and let it cool over night. This is now hardened. Well done.

If you really don't want to do this step, you can dodge it and just use the I beam.

To place your 'anvil' you want to get it on something that won't shift when you hit and won't crack either.

If you stand naturally, arm at your side, the heigh of your hand is wear you want to top of your 'anvil'.

I used some bolted timber, this one's up to you, what ever works.
If you used the I-beam path then you have the problem of making it stand well. All I can say is good luck coming up with something. I should say you want to stand it like this...

I know this sounds a bit harder than maybe tongs or something but it'll teach you everything you need to know for all kinds of blacksmithing, not just bladesmithing.
(You need tongs too)

Get your hands on some steal, I don't care how or where. You can buy steal off line or you can use just random steal you've found.
(Leaf springs from cars work well for larger projects like swords)

Cut your steal to size using a circular saw if you have one, If you don't, green text.
>Heat up as much of the bar as possible (using bellows)
>Place a Thin bit of steal at the right length, at right angles to
>Hammer the thin part in.
>Repeat until you can 'snap' the heated steal.

Now you have the right size bar, get the fire started and heat it up, using the 'bellows'.
Take it to the 'anvil' and hammer the shit out of it. This parts pretty brute - just get the shape right flatten out the blade part and square up the handle.

take care not to snap the steal, never hammer if you're unsure if it's hot enough, don't waste your effort this far for a few $ of charcoal.

Now you have the general shape it gets harder - much harder.

Working on the handle now, you want to, as seen in the picture, extend the handle, getting thinner all the way. Feeling confident? green text.

> Heat the handle up like a mother fucker.
> Get two Wrenches/ Grips
> One at the top of the handle - one at the bottom
> Twist in opposite directions to create a spiral in the handle.

With the handle being about 250% larger than you want it to be, bend it back on it's self as seen in the picture.
TAKE CARE - Don't go folding the handle towards the blade, I do that shit all the time.

Once you get that handle curve finished you need to do something with that point.
I go with a swirly look but if you don't feel confident doing that you can fold it back using grips/ Wrenches.

Handle finished!
(If it's too big/ small undo the bend before trying again and heat it up more than usual, need to get rid of any stresses)

I might... It depends if I deleted them off my camera or not, I'll look for you after I finished this little tutorial.

The blade is pretty tricky.
First of all you need to shift it forwards, the reason? You'll see when you do it, not convinced? Green text, I guess.
>When you make the bevels the steel at the edge will be thinner
>So when you hammer it down the thinner steel will spread out more than the ticker steel
>This will make the blade fold backwards (Like a schimitar, I guess)

A bit like the shape in my picture but you'll need it about the same amount as the desired curve, just added on to the original... Fuck it, i don't even know how to describe this.. about as much as you can bent a ruler with out it snapping should be fine.

Now you need to be careful here... Holding the knife at an angle of 5 - 15 degrees to the 'anvil' hammer down, close to the edge. This'll take a while and isn't worth rushing. Take care to keep the angle you hold it to the anvil the same each time and not to hit the blade into the anvil, but against it. (To avoid it folding over on it's self)

This part will be easier once you're behind the wheel - just think logically bearing in mind that the thinner steal will spread more.

Once you have the general blade shape - clean it up as much as you can. Level out the back, if you like and try to make the tip look presentable.

I'll do the heat treating now.

I would say about 15 mm thick,
150 cm long and as wide as you want it really.

You have to think that the steel ain't going anywhere, only shifting from place to place.

A few things to keep in mind is that you want the balance of the sword to be about 6 inches from the cross guard and you'll want to steel to go right to the pummel, or bottom of the handle.
Handles are often longer than you'd expect them to be with swords.

>>17836
I've never really come into a place where I could get hurt badly.
I keep my distance from the forge when the hair dryer is on, take care not to drop the steel and all that. (All be it now I have a proper forge and anvil [still use the old BBQ trick for larger projects])

If you fancy cheating a bit and giving it a once over on the bench ginder, do that now.

For heat treating what you need to do is throw your knife in the forge and wait until it glows all over. The blade is the most important part to get hot. When you think you have it hot enough pull it out and let it cool down slowly at air temp. This will remove any built up stresses in the blade (The handle curve and that)

Throw it back it, get it way hot again, pull it out and using a magnet (neodymium is suggested) stuck to your grips test to see if it sticks to the blade at all. If the blade is at all magnetic put it back in.

Once there is no magnetism stick it back in for two more minuets and ready yourself for the biggest wanker of all. Grab that knife and dip it in your oil, nice and quick - don't let any part of it cool down faster than the rest. provided you do it right it should be ok - it may shatter if you're too slow dipping it in. Hold it in there nice and long - 20 seconds.

It's now a sheet of glass. That shit touches anything it will break.

Take it up to your kitchen and wrap it in some tin foil, nice and tight. Pre-heat your oven to 210 - 230 and place it in there for about 2 hours.
Pull it out and let it cool naturally. You have your self a knife, all be it a blunt one.

You can sharpen it on an oil stone, then a wet stone, then a strop.
Or you can cheat a bit like I do and get it on the grinder and then strop it.

A Lanyard on the handle can add a few mm on if it's a bit small.
If it's too big you can tie a lanyard really tight around it and pull it in a bit - it should be a bit flexible.

and when you buy your first anvil be sure to ask.

If they say yes, it means the anvil is harder, or as hard as the hammer. This is what we want.

Actually, to add further to that, you could even get away with using a pipe, inserting the tang into it, bending quickly, then removing the pipe. Afterwards, a couple of taps to adjust it would work.

>>18269

Ignore the statement about not hardening it. You will want to harden it, and then temper it based on its use- a rapier would probably do well to be drawn to a spring temper, whereas a broadsword would want a bronze or peacock temper. The hardness you want varies on its applications, materials, and manufacture. This takes lots of practice to do well.

Also, start with knives for a while. Big blades are trouble waiting to happen if you're inexperienced.

I live in canada. I'm likely to have the money for this within a couple of years as well as I'm going into the Navy, and I'll be paid pretty goddamned well.
I plan, a few years down the line when I actually know what I'm doing, to build a studio to make furniture and celtic styled gear, maybe a bit of art deco stuff as well(I'm very into steampunk, yeah yeah i know a lot of people hate it but when it's done properly and.or subtly it looks amazing), and possibly sell some of it.

Then you should be fine with US steel terminology. Look to Grainger for tools, ABANA membership gives you discounts.

I don't remember if Canada has a specific blacksmithing group, but I'm fairly certain ABANA has you covered there. You'll definitely want to start small if you're working up to pattern welding (indeed, that and crucible steel blades is a goal of mine, one of several). Just focus on basic forging techniques for a while- I'm not even a journeyman according to CalSmith, but I'm getting there. Expect to make a lot of nails, they're good practice.

What part of Canada? There are a few people up there that do some schooling- I know of a school in BC and a school in Ontario. Darrel Wareham is in... I want to say Nova Scotia? I'd need to double check.

Hopefully soon I'll be able to post pictures of an iron smelt, whenever an associate of mine sets a date for it. We did it in July, I have some photos floating around there.

just wanted throw this out there.
Walk along a railroad track for a few miles, have a nice little hike. about 10mi~ away from my home there is a barred off dirt access road that leads along the tracks for about 5 miles. usually, every 2-3 miles there is a small pile of rusty railroad tracks, which Im assuming are used as replacements if any of them break/get misaligned.

Invested 10$ in a boltcutter at harbor freight, cut off the lock, threw it into bushes, drove my truck down and got 3 rails with the help of a friend. drove off with enough for a few cheap "anvils" Works well if you get a plasma cutter (oxyacet works too) and cut them into 3 foot lengths, only problem we have is they are slightly convex curved, so unless we focus things come out slightly curved. the new tracks on the rails are perfectly flat, but we realllly didnt want to take them off the track. replacing them would be even more illegal than just taking old ones.

Just grind 'em flat, or fill the hollows with welding rod, THEN grind it flush.

Alexander Weygers (rest in peace) has a book that details the shaping of railroad track into a rough anvil, and from thence hardening its face. You could probably get away with using it in its default state- I've used a mild steel anvil before, it's not perfect, but it works.

Here's a shot of the tuyere. It's made from copper sheet (1/4" thick) forged into a cone, and hooked up to a set of pipes. There is a cap at the end- removable, for poking around in there- with a lens embedded in it so we could keep an eye on how it was going on in there. The lens is from a welding mask, if I remember correctly.

The tuyere is connected to an electric blower. With enough air moving through the tuyere, it stays cool while also serving to increase the overall temperature of the furnace when it's going full tilt (more air = more oxidizer for COMBUSTION!) The reasoning behind using a copper tuyere is simple- while it might melt and contaminate the bloom, it won't break like a ceramic tuyere, so it's reusable.

When smelting bloom iron, you typically want to have a little slag in the bottom of the furnace when you start out- it helps to capture the iron as it welds to itself, and bring it together.

Pic related, it's slag. If you look closely, you can see some metallic oxides on the surface.

Yes, you'd want to, but you're more likely to just start out with making basic shapes before you make tools. My first tool was a screwdriver.

Word of advice to anyone thinking about going out and nicking some rail lengths.

One. Don't be an idiot. Don't be seen, and don't let anyone know what you found or where you got it. We wouldn't want a bunch of scrappers swooping in and ruining the fun for the rest of us.

Two. If it's lying in a pile near some ditch somewhere, fine, take it. It'll probably be rail that they've already replaced, but didn't care enough to cart off, and just left there.
Just don't go tearing up rail that's still in place, even if the line is officially abandoned. Every bit of rail that's torn up is one more bit of rail that can't eventually be re-activated, or bought and used by a Railroad Museum, or something.

Also...
>only problem we have is they are slightly convex curved
Duh. It's not due to wear and tear either, the edges are supposed to be rounded like that. Look at a train car's wheels once, they're not perfect discs -- they're slightly bowl-shaped. It helps lead the wheelsets into the curve because (physics that I can't be bothered to explain here, look it up if you're interested)

But anyway. If you really need a flat surface, can't you just turn the thing upside-down, build some sort of u-shaped trench to sit it in, and use the bottom side of the rail?

Sure.

We charged the furnace every 10 minutes with the aforementioned mixture. The playground slag and calcium carbonate are for slag content.

Unfortunately, towards the end of the smelt we started to have a problem. That black-grey stuff you see coming out of the front of the furnace? That's unreacted ore. It turns out that the bloom had fixed itself to the side of the furnace and was so large it was blocking the ore from reaching down to the base of the stack where it could react. When we started to dislodge the bloom with a sounding rod (rebar), lots of unreacted ore came out.

You can get a hamon via differential hardening or tempering. Hardening is the clay method, where you paint the blade with a clay slurry to insulate it during the quench, retarding the conversion of the steel from austinite into martensite. Differential tempering is where you temper the blade to the desired edge hardness (usually in an oven), then immersing the part of the cutting edge you want to stay hard in water to remain cool while you draw the temper on the back with a blowtorch.

As a beginner, I'd shy away from differential hardening for a while. It takes a lot of practice to get it to not warp, and while you can do some straightening in the tempering process... I'd practice a lot.

You also can't (to my knowledge) do both a differential hardening and tempering on the same piece. At least, I've never tried- it might be possible.

ANYWAYS...

Here is the ONE good picture I have of Jeff working the bloom under a power hammer (in this case, a Nazel 4b).

>> No.19072

>>19027
interesting stuff..

so let me make sure i have this in my mind the right way.
You cook up the iron-bearing sand or metal-containing rock bits and melt away/burn up much of the rock and mess.

You end up with a big sponge of metal and slag. You hammer and pound and heat and hammer more this iron, breaking up and breaking away slag, until you more or less have a piece of metal that can be worked with? and That is wrought-iron?

>> No.19080

>>18993
No OP, but I'll throw some info at you.

As I understand it, the curve is actually a result of the heat tempering. Clay is placed on the back of the blade and the edge of left bare, so when it's plunged in the water, the edge hardens but the body remain soft, and the contraction of the edge causes the blade to curve and in some cases even crack(meaning you'd have to start all over).

So you'd need clay and large basin for tempering.

IIRC, the fuller is usually added after forging, but I could be wrong.

Anyone who knows more, feel free to elaborate/correct.

>> No.19156

You guys and your railroad anvils and barbecue forges claiming that's beginner equipment- although don't get me wrong it is indeed okay to start with.

Basic blacksmithing can be done with as little as an ordinary campfire on a breezy day, with nothing more than a heavy plate of metal or even a flat rock as the anvil. Just take care to build the fire such that the wind howls through it, driving the embers inside to an orange-yellow. I still use these methods when travelling to repair my camping equipment, some 10 years later after learning blacksmithing.

I actually use pine slabwood as the fuel for my forge, and with it can achieve temperatures so hot that the steel melts. The trick to it is being able to arrange the fire such that it rapidly produces a thick bed of coals in a place where enough air is whipped through it to raise the temperature.

As long as you have a way of reaching the required temperatures using whatever you have to work with, you can use that as a forge to learn at least the basics. A good forge is really only required for more advanced techniques.

As for Anvils, the object of your search is simple: It needs to be sturdy and rigid, capable of backing up your hammer blows with a flat surface that provides the stiffness of the earth.

Later on if you decide you like it, then worry about constructing a proper forge or buying an anvil.

Just beware when searching for anvils- many cheap anvils are in fact Cast Iron. These anvils while functional will quickly become damaged and useless for quality work, as well as having a high likelyhood of cracking in use or giving poor performance.

>> No.19166

>>19072
That is bloom iron, not wrought iron, there is a slight difference- while both have a notable slag content, bloom iron is even more buttery underneath the hammer, and doesn't get red-short like wrought- you can work it at high and low temps, it doesn't care.

What happens in the furnace is the ore reaches forge welding temperatures and starts to stick to itself. As the pieces gather, they keep welding into a big mass, usually containing bits of slag and even charcoal.

At this smelt, the bloom was worked without reheating to condense it a bit. We left it to cool, and I assume Jim worked with it the next day.

He would have to carefully stack the smaller bits and pieces that broke off, probably wired them together, and then forge welded them together.

>>19080

You actually described the quench, but yeah, pretty much.

What happens when you quench it is that the clay retards the spine from cooling as fast. As such, the austenite of the hot steel is converted to martensite on the edge, and pearlite on the body and spine. This leaves you with a hard edge and a softer body.

Afterwards, you temper it to the desired hardness, which also relieves stress from the quench.

There are also other ways of hardening steel.

To answer your question on plate- I've not done much dishing or repousse.

To be fair, though, you want to forge your edge to as close to finished as possible- not so thin, however, that you get distortion and accidently burn the carbon out of the steel when you're heating it, though. About as thick as a dime for the heat treat, then you can finish it to sharpness on a belt grinder. Use new belts if you can- old ones will cause more friction which means more heat which means more chances of drawing the temper softer (and you just spent all that time getting it right, damnit!). It's good practice to drunk your workpiece in water often to cool it. Also, I shouldn't need to say this, but I will anyways- you're SHARPENING something. It will be SHARP. If you slip, you can injure yourself. Wear gloves.

Tripoli is just abrasive enough that you can get a really nice polish. I suggest hitting your piece with it on a buffer wheel (carefully, both because it's sharp and because you risk drawing the temper from friction). There are even finer polishing compounds out there if you want a mirror finish.

Now, while I do like shiny things- sometimes it's the best thing!- I generally prefer a black manganese phosphate finish for utility cutting tools.

You can check, you know. My claims aren't unsubstantiated. But then again, you might not know how to check for samefag.

Anyways, a rail track anvil is better than no anvil, and they're also easily modified to become dies for trip hammers. And they do work quite well. Yes, the web is thin, but for a trip hammer die they're already perfect for drawing, you can cut it off at the web and face weld it to a ram of mild steel, or cut a slot in your ram to let you use the web as a tongue-and-groove setup for interchangeable dies.

I'd start with trolling your local flea markets for tools. For all your hammers, you're going to look for ones without chipped faces or scars. Chipped faces are bad, simply because the hammer is going to leave ugly scars on your work, the same for scars and cuts on the face. Do not, I repeat, do NOT use carpenter (claw) hammers. If you accidentally strike the surface of your anvil, it can rebound and hurt you. You'll want a ball pein, and if you can find one, a cross or straight pein. A cross/straight peen will look kinda like a wedge shape on the back of a hammer with a fairly wide radius. Again, make sure it's not cracked, chipped, or gouged.

You CAN use wrenches and such for tongs until you're further along, just make sure to clean their grip faces up so that they don't leave marks. Also, you're going to want to make tongs because wrenches suck for general work- for fine detail work or work where you need leverage they're great, less so for just holding something.

Now if you can FIND tongs, get them. If they're funny looking, don't worry, you'll be able to reshape them eventually.

Chistles and punches... those are things you're going to want to look to blacksmith suppliers, such as www.theblacksmithdepot.com, or Grainger Tools, or Northern Tool, or McMaster-Karr. You CAN find some at flea markets, but again, they need to be in good condition and they need to NOT be Chinese- I've had cheap Chinese punches and they're shit.

>> No.19735

>>19655
Oh, yeah, I don't mean to say they're useless. I've used one before. In his book (i forget what it's called) Jim Hrisoulas swears by 'em. I hear you can use them vertically, too, where the head of the rail itself is just going straight down, and I think that would probably work pretty well as far as MASS goes. It's just that if you're setting out to make an anvil for yourself as a project, you might as well make it something better than a rail anvil.

Gloves, yes, a good pair of gloves. Now, some smiths use them on both hands, some don't wear them at all, some wear them on only their non-dominant hand. You'll figure out what you're comfortable with.

Files... I'd look for a couple few good mill bastard files. If you're looking to do a lot of filing, invest in a belt grinder to do most of it (carefully) then to finish it by hand. Again, don't buy Chinese- you never know exactly what steel the Chinese are using, and I've even had a few files that were made out of mild steel. Don't buy Chinese.

For stones... you'll want to look to a synthetic whetstone. The Japanese waterstones ARE god-tier, but they're also hellaciously expensive (2 grand for a set).

Oh, and here's an important thing. I'm going to parrot Norm Abhram for a moment- "Always wear these, safety glasses". Get a good pair. Not just sunglasses, something rated for it.

If your choices are a big mild steel block and a section of rail anvil, take the rail anvil. Just bolt it down to a big, heavy hardwood stump and treat it like it's a big, heavy anvil. It will stand up to the abuse, and it will work VERY well.

>>19775

Continuing.

A good drill press. Again, not Chinese. Spend the money to get a good brand that will work, don't hit up Harbor Freight for anything other than cheap shit that you don't care about.

A good belt sander if you can't find a good belt grinder. There are plans floating about on the internet for a 72" belt grinder, you can probably find them on iForge Iron or Don Fogg's forum, and I'm fairly certain on ABANA.org.

What else... I'm trying to think of what else you might need...

Oh! A slack tub. Use a steel bucket, a steel trashcan, or a big oil drum- as long as it's steel, so you don't accidentally burn through it (it is possible if you're trying to cool off a hefty enough thermal mass).

You'll want your shop to be well ventilated, and well lit- but ONLY well lit if you need it. When you're otherwise working, you want your shop to be dark so that you can better see the temperature gradient of your hot iron.

What that will do is one of two things.

One, you'll bake the rust and otherwise accomplish nothing, or two, you'll get an uneven hematite coating. You will not be bluing them.

To blue something, you need to clean the metal, first off- hit it with a wire brush until it's shiny. Don't get any grease or fingerprints on it, it'll show up. Wipe it down with acetone, then clean it off with water and dry it before bluing. Then you have a few options- you can fire blue it, where you slowly heat it to ~525-550 degrees Fahrenheit, or you can salt blue it. Both methods are out of your general reach- the first takes a lot of practice, and unless you have access to a gunsmith the second is unlikely. However, you can cold blue something with chemicals. I personally recommend Brownell's stuff over Birchwood Casey- it's the same shit, only cheaper.

1) what the hell is a 'fist' in the context of something capable of being made from railroad spikes

Tips? I linked a YouTube video earlier. That's a bit more than what you're probably looking for- simplest I can think of would be a slit-and-drift, monosteel axe. You'd take a bar of... 5160 or 4140 steel, start rough forging it to shape (squaring it and upsetting the portion that will become the cutting edge), slit the area that will become the eye, drift that with successively larger drifts until you finish with the size you want for your handle. Then you'd want to spread the cutting edge with your cross pein, forge it to shape, profile it, do a triple-descending normalization, harden it, temper it (bronze for the edge, peacock/spring blue for the body), grind and sharpen it.

I'm going to add on to my post of >>20371. I should have asked this, actually- what is the purpose of the axe? Splitting kindling, felling trees, what?

If you're looking for something quick and dirty, you can shape a lawnmower blade into something that is part-axe, part-machete. That, the more I think on it, would be the easiest thing you can do.

Also to mount an axe head, the eye of the axe is tapered, and the handle is larger at the head so that it wedges in place naturally (before you add wedges). Ideally you don't need to use wedges.

I can't see why not.
Basically it's to have the blade cool down quickly; the reason we use oil, not water, is because when we stick the steel in, the oil will conduct the heat better and make the heat change less dramatic, not to break the steel.

So long as, and as far as I know it is, the conductivity is similar you should have no problem.

Also, provided you keep it out of the rain you should never really need to change your oil over.

No you can't. Leaf springs work because springs are hardened so they're springy and not ductile.

>>17931
200F is way too low for a temper on spring steel, not to mention random mild steel won't harden in the first place. You've got major grain from overheating, and you've got no normalizing cycles either, meaning even more potential brittleness. You want at least 325 in a oven stabilized with bricks to keep heat steady. Ovens maintain temperature with off/on.

Goddamn. If you're going to make people waste their time making a knife, at least direct them to buying $20 of usable steel, and there should be lots left over for practice. Scrap worth of spring steel is the same as mild steel, and spring steel is only a little more than mild steel new.

Mild steel does get harder - weather you can say it's 'hardened' is a different question. Which is why I said it's optional as you can make do without it.

The fact that leaf springs are hardened means balls - you normalise it long before it's hot enough to beat anyway at. I went through hardening as well, so yes, you can use and steel. AND yes - I am aware that some steals are better than others but I'm not opening a university here, I'm trying to encourage people to the hobby.

And in fairness - this one is my bad completely, I meant centigrade, not Fahrenheit - about 420 Fahrenheit, I believe.

>Stabilized with bricks to keep heat steady.
You are aware that if you leave an oven on it doesn't just get hotter and hotter for all eternity, yes? you seem to be unaware of the fact that they do in fact maintain a constant heat.

And finally, I know it doesn't make a better knife, my 'tools of the trade' so to speak are a bench grinder and a grinder with 12 tonnes of sandpaper. I do blacksmithing as a hobby and nothing more and was trying to show people cheap alternatives to getting into it.

Yep, was at that moment I realised I may as well of been talking to a chimp. Regardless of whether you enjoy blacksmithing or not holds no bearing here - stainless steal is a load of bull for an edge. Unless you're making EDU anything but carbon steel.

A mild steel anvil is not going to stay flat, especially if you do any cold work. Railroad tracks work well because they are both hardened, and have addition work hardening from tons of crap rolling over it.

>The fact that leaf springs are hardened means balls - you normalise it long before it's hot enough to beat anyway at. I went through hardening as well, so yes, you can use and steel.

You have no normalization to reduce grain size, since you're likely overheating to make it easier to forge, meaning large grains and increased brittleness.

The fact that springs are hardened means lots, it means spring steel can be hardened to a practical and usable hardness, something your A-36 scrap rebar won't do. It will just essentially be a pointy piece of iron, the same as taking an piece of unforged rebar and gridning it down to a point. It will be pointy, but it won't hold much of a cutting edge. Worse than your dollar store knives.

Extra normalization steps are to reduce grain size, and increase toughness. I'm not talking about annealing, or getting it red hot for work. Not all steel can effectively be hardened either, including most scrap and construction grade steel. Just because you heat treat it doesn't mean it will get hard.

They don't. Or at least, lots of older ovens don't. You should be using a thermometer anyways, since older ovens, like many people have, can be off by 20-30 degrees.

A mild steel anvil can also be much easier to find/make and use as a temporary anvil until you get something better. Believe it or not, some people do have difficulty finding them. Better something than nothing. And if you have the space, you can try case hardening them but that's generally a bit beyond most people by themselves. The other option would be putting a face of tool steel on it with a TIG welder, though you'd need to be careful, and it would be an arduous process of many hours.

On stain-resistant steels... well, you can get a good edge from them. It's just more difficult to forge because they typically have a tendency to red short (I say typically, because it varies on their alloy), and other than an increased hardness and edge retention, there's no practical benefit (in my opinion, some people really like it).

That is why I don't forge anymore. I can get better performance and stain resistance out of stainless steel, but it doesn't forge. Also the fact that forging doesn't really add anything except making unusual shapes. It isn't that forging is not fun, but it is prohibitive in making a superior knife unless you've got a large PID forge and some major power hammers.

>other than an increased hardness and edge retention, there's no practical benefit (and stainless)

That's like saying "besides being better there isn't any real benefit"

>> No.30723

>>30680
Not really. Edge hardness and edge retention should be based on the purpose of the knife/tool in question. If you want something with a softer edge because you prefer having a knife you can easily sharpen in the field, then a stainless blade is probably not in your future. And if you want a knife that holds an edge forever, but you don't want/need the stain resistant properties (you're not diving or in a high-humidity environment), 52100 would be a good choice. The purpose of the tool determines its materials.

Bro, I can make stainless whatever usable hardness I want to. If you want it 60, I can make it 60. If you want it 58, I can make it 58. If you want it 52, I won't, but can make it 52. If you want it dead soft, I could but there isn't a point to that. It is called tempering.

And I can make my stainless perform just as well as most 52100, minus the edge quench bend 90 degrees and have an l-shaped knife tricks. Being stainless isn't a negative thing. It might be superfluous for cutting cardboard boxes, but even then it gives more resistance to chemical erosion of the edge.

And seriously, I don't know what is with this shit argument about sharpening in the field. If your edge lasts longer, you don't have to sharpen as much. If you carry a slipstone, then you can sharpen anyways regardless. If you're sharping on random rocks, then whatever. The abrasive compounds in rocks are generally a order of magnitude or two higher than even really hard steel. The small difference in relative hardness only means it will take longer to sharpen, not that it will be unsharpenable.

You go to train yard, with all the turntable things and bring a pack of beer. I beams aren't the same as railroad tracks. What makes railroad tracks great are that they are hard, they are even harder because trains rolled on top of them, and they are smooth and burnished for the same reason.

Otherwise you want to find a post of hardened steel, a very large sledge head works, but is small, and imbed it in a bucket of concrete. Hammer heads are hardened so nails don't mess them up too much, and that gives you the striking surface. The bucket of concrete gives you the mass.

O1 is okay. It has lots of MN making it easier to harden and not fuck up, but it is pricy compared to spring steels, even though it may be better, and more finicky than 1084/1085. A beginner can make something useful out of O1 easily, but it won't be better than something made out of cheaper steel if you don't have good skills. 1085 is the easiest steel to work that will give you near full hardness potential, although it isn't common. 1075 and 1095 are much easier to find.

The fuel is cheaper. Heat cycles are much faster and you don't have to keep it on.

With a coal forge you have to keep the fuel burning the entire time, and the stuff has to soak in the heat for quite a bit relative to coils. Not to mention is is cleaner, and you don't have to spend time sourcing fuel. Of course you need an actual industrial power line.

>> No.34663

>>34645
Stop it with the nanotube shit. Seriously. Damascus steel isn't even any stronger than normal steel. The patterns were due to alloy banding or carbide banding, meaning you have bits of hard carbide, and bits of soft steel, except unlike normal steel where they are evenly distributed, it is not.

The reason why Damascus steel was superior was because back then the Europeans were using steel that was 0.2-0.4% carbon, meaning it did not get very hard. Its why you see little dings in swords in museums, and why they can beat katanas and shit in stupid toughness tests.

The Damascus blades had C values of 0.8 to over 1%. Talk to nearly any knife or sword maker today, and they would not consider using steel below 0.6%C.

Pattern welded steel can be done in various ways, not just cable. Making a good billet is difficult, but the process is essentially just smashing together lots of pieces of different steels while red hot and forge welding them together.

No, you need to take it back to a recycling plant which they probably would already do. There are a few applications you can forge with a canister of powdered metal, but these are extremely clean powders. Melting and refinement of steel is extremely difficult, and you might as well start off with ore sands. Even then for the effort, you won't get clean steel, just steel you made yourself, at a cost much higher than buying steel (see tamahagane). The other steels can be ordered as powder, but this is used as a gap filler in making some Damascus billets. It does not get melted and purified, so anything dirty in the powder will end up as an inclusion.

%C isn't a hardness rating per se - it's a percentage of carbon present in the steel. Pure iron is relatively malleable as compared to carbon steels.

You can have too much of a good thing of course, and excessive carbon in steel can lead to a very brittle mix.

Lots of other things determine a steel's hardness apart from its component materials, however, such as grain size and shape.

Don't go ripping out railway that you think is unused (even if it is), as it could still be theft. Also, it is kinda a jerk thing to do in my opinion.

DO scout along the rails for already-removed rails, even spikes.

And ok, if the track is truly abandoned and decaying, cut off from other lines, it might not be terrible to take a bit of steel. You would need some serious cutting gear, like a plasma cutter (and generator that can run it, some way to carry all that, so forth) to actually cut rail. Look for short sections, but a "short section" might mean that it is only 5 feet long, still trouble to move.

You might find a hardened old sledgehammer head as a better "starter" anvil to screw around with some nails and things, then buy a real anvil.

There are numerous grades of rail. Most I've seen work harden on the running surface, but the lower flange will not workharden. I'd suggest cutting from the bottom up with a saw until the lower flange and web are cut and possibly a bit into the top flange. To snap the rail, lay it over another one (still upside down) and whack the end with a BFH or if you have a loader, etc. place a sort length underneath the cut at right angles and drop the rail 18"-2' onto the lower rail. It should snap off.

A torch will work OK too. Torches are not affected by workhardening. Depending on how heavy the rail is, you may need a larger tip. 100#/yd rail has a top flange thickness of +/- 1 1/2" so your tip will need to be able to cut that thickness. Cutting rail with a torch is easy if you are willing to keep the torch at right angles to the surface following the relatively complex contour.
