This is why I do canister welds. Box the stack in thin steel and put a shred of paper in there to eat up the residual oxygen when it burns. I wrap the stack in stainless foil so it doesn’t stick to the box. Clean welds.

This series is the most informative out there about knife making. Please keep up the good work.

After watching other knifemaker's youtube pages, it turns out these other craftsmen/ladies are not the gods of steel and dark magic I've thought them to be, apparently god is an Essex chap, and is called Graham lol. Jokin aside, I'd love Graham to explain Dirty Damascus, unground rusty cartwheel rims sandwidged by bandsaw blade for example and why it works, when grinding flat is the first rule of making sharp pointy things. ANOTHER GREAT SHOW, so refreshing to see great content without being subjected to someone's dog /cat/fish getting petted, tea being made or beer being judged.

Not all Essexboys are chomps hey 😂😂😂 Cartwheel rims were wrought iron - almost pure iron with a lot of impurities that when etched give a watery pattern, Most saw blades contain Nickel - it increases toughness at high (ish) hardness. Makes a reasonable combination for Damascus that will weld easily.

@RobanyBigjobz

Жыл бұрын

I should preface this with context: I'm a hobby maker who makes a handful of knives a year mostly for my own amusement and the enjoyment of making them. The issues I run into are things like: choice of belts (already covered), choice of steel (already covered), proper heat treatment (Graham exists), overheating the edge/tip (personal lack of skill, only happens when making a Bowie-style for some reason), wanting a better grinder (need to move house for space). Other than that there's figuring out when you have got all the scratches from the previous grit out when using a grinder. The scratches are all parallel so I find it really hard to tell if all the 60g scratches are gone when using a 120g belt. End up doing a lot of hand sanding because of this. Answer is "get better at grinding by doing it more" but I haven't put in enough time for that yet.

European medieval method of making swords from spring steel or the Japanese method of katanas with a combination of harder steel and a softer outer part . My question is is it possible to make either a sword or a hard and durable steel on the inside and spring steel on the outside that is flexible and at the same time more resistant to blunting? I'm not sure if the same temperature can be used for both types of steel to get good internal hardening and spring effect at the same time. As far as I understand, the best katanas are made of 5 layers, the 3rd is thinner than hard steel, the 2nd and 4th are of medium hardness and the 1st and 5th are again of higher hardness so as not to be scratched from the outside. But is it possible to make it flexible and at the same time stiff in the middle?

Chemically speaking I knew there should be a way to do it and the information you just presented was exactly what I had been looking for. Thank you very much for this very informative video. I would like to see a video on reactive gases as well if you have the time in your future Productions. Thanks again for your content. I will check out your website and hopefully order some materials from you.

What do you mean by putting a reactive gas in the canister? Since gas expands when heated, it will tend to 'blow out' welds. So how do you keep a canister filled with gas intact while heating it to the forging temperature?

So i have a question. Where could i get a reactive gas to use for high alloyed steel? Ive been experimenting with forge welding high alloy steels. (And burning through too much money doing it). And ive tried a few things, but i hadnt considered getting a reactive gas for to make sure the chromium oxide layer is removed. I just tried to clean it off, and weld it quickly before it forms again. (With limited success). Im willing to try anything at this point.

Could you give an example of a reactive gas for stainless forge welding? I use argon with my tig, could that be applied to this process as well?

@GemAppleTom

Жыл бұрын

Argon will protect a steel from further oxidation and is used to protect fairly reactive metals like titanium. Argon isn’t going to remove an existing oxides though. I’d not very familiar with what ‘reactive gas” is, though. From basic principals I’m guessing it contains Chlorine or maybe Sulphur which will react with chrome oxide and help remove it.

Maybe grind off the oxide in a vacuum chamber then stick it in the canister and cover it with powder

A coal forge works the same way as a gas forge but is less easy to control. Once hot, you need to be able to control the amount of air going into the hot zone so that the hot coals use up all the oxygen. I believe in ancient times smiths would also use silver sand (very pure silica) as a flux.

Is there other fluxing agents that you would recommend other than borax... And what are some of the other reactive gases that you use when you forgeweld stainless steel?

@UKBladeshow

Жыл бұрын

I can ask our makers as well what they use for fluxing but borax can be a pain in the neck as you know - ruins your forge!

Question. So if you have your correct gas and air mixture in your kelm. Is it still recommended to use Borax or does this correct air and gas mixture eliminate the need to use Borax? Tired of having to clean the mess or reline from the damage the Borax is done

@GemAppleTom

Жыл бұрын

That would depend on what steel you’re using. If it’s a plain carbon or low alloy steel you should get away without the flux if you have the right gas mix in the furnace. Stainless is another matter - you’ll still need to get rid of the chrome oxide layer somehow before you’ll get a decent weld. I’m certainly not an expert on fluxes or reactive gases that would do the job though - hopefully others will be able to answer that question.

@grahamclarke4470

If you get the gas/air ratio right you don't need borax. Once I stopped using borax I cast a new 1 inch layer on my forge floor and haven't had to touch it again for several years now.
