i loved the short, it mirrored my experience really well. some of the reactions to it were bizarre; it's like people thought you were attacking them, historical blacksmiths or whatever else they'd based their identity around, and then mentally tuned out and didn't bother listening to what you were actually saying. ignorant people can always learn, but only if they want to.
An interesting read is Mechanick Exercises or The Doctrine of Handiworks by Joseph Moxon (1693). The chapters on smithing and heat treating especially. In it he describes annealing, hardening, and tempering steel. However, what he calls annealing appears to just be a single normalization cycle. Then he also gives a few more speculative ways of annealing steel, which might have worked in that part of the recipe was for the steel to cool very slowly.
Always fun to watch your videos, of this style! Thank you for this! I also appreciated your video on the various face shields. I’ve been saving my pennies to pickup an Airshield Pro.
I reckon you'll love it! I've been using mine all day today. One extra tip I can offer on it - the head strap inside can start to rub painfully during extended use sessions, so just stick a little bit of something padded or foamy up in there to relieve it. Makes a big difference!
Thanks for the follow up, I'm of similar opinion to you on these issues. I'd like to say , however , that I couldn't hear about 50% of the initial one so I'm not surprised some jumped to conclusions. It's not the first time I've found difficulty hearing your vids so hope this helps. Keep up the vids please, not everyone goes into the depth you do. Thanks and cheers
In the age of cheap thermocouples and digital readers there's really not much excuse to spend a hundred bucks to get one a good quality reader and some spare thermocouples. Heck, you can cheap out and it'll probably be 'case of beer' money if you hunt around for some bargains or on a sale. Thermographic readers are a little bit more for something that's not crap, but likewise, with some hunting around for a discount or 2nd hand you might be able to get one for fairly cheap and its not like you'll never use the thing, they're especially good for finding electrical and car components with problems as well.
@@ValhallaIronworks I don't really like the magnet test, if you're really hard up for a solution on simple carbon steels I guess you can maybe wing it. Most of those start austenetising around the 750C mark so if you can get them in the sweet spot of 800-820C for most it will probably mean something happened enough. Hopefully. Once you're getting into more complicated alloys and hold times all this stuff goes out the window and you do need some precision on your temps. Now the reason I'm not a fan of the magnet is that coming from the dirty toolbox and dirtier language side of engineering is that I know what happens to magnets when they get hot. All sorts of stuff increases activity in the magnet's metal when it gets hot and essentially degausses it so you can end up with very hot metal and a hot magnet that won't stick to anything- not to mention that all permanent magnets are created equal and some respond to temperatures differently to others. That may seem trivial, but its never mentioned in any place I've seen people doing magnet tests on youtube and in a vain attempt to bring some kind of practical science into this damn craft, it really should be said that your magnet also becomes useless once it gets hot!
@@krissteel4074 i got pretty good with the magnet thing after relying on it for my first couple of years doing this. the idea is to not let the magnet get hot. you just tap it along the blade and see if it sticks. if the magnet actually gets hot, you're doing it wrong.
Colour don't mean shit, I just assume everyone is talking about white heat 😂 Use a thermocouple ffs people 😂 Non magnetic is also white forgewelding heat 😂 it can be anything you want it to be
Its the same with.... Japanese katanas. People think that ""old good hand made katanas made of 100000 layers by one guy are better than modern steel swords... not really. Of course if you buy cheap Chinese katana from ebay for 100 bucks you will get crap, but get equivalent priced/quality sword, not need to be even katana, and steel in it will blow away your old katana in terms of sharpness, toughness and quality. Hell, even some modern materials used to finish its look make it better as, some of traditional material to make eg handles dont really last long or are best for grip. I always laugh that katanas are made from layers because they use crap steel so only way to keep it together is to layer them :D Yeah I know that its not truth(or... is it?) but its just that another thing that people cant get in to their heads that we improved a bit in some ways over last years... its not like steel is steel no matter from what era.

It was very strange, to be sure!

I'd love to know how the original author would find our understanding of steel today!
Great advice! Read a book! A lot of people would benefit from that

haha gas forges are LOUD! This is why I prefer solid fuel forges with hand crank blowers. Much more peaceful.

To be honest, in a pinch I'd be happier for people to just use the magnet test instead of using colours!

You just gotta beliiiiiieve!
Reading is to hard ..for some!
Haha it sure is. Hope you're doing well over there, handsome!

Haha yeah that old argument loves to rear its head from time to time. Blades that cut through gun barrels!! 😂
