Thanks! the forge is a brake drum, there are better ways to make a coke forge but this way is pretty quick. I figured using glass was worth the risk for visibility, may have changed my mind if somehow one shattered though!
Gee that didn't look hot enough, but you had the magnet. and using glass, you're lucky the glass jars didn't crack as the oil can get mighty hot with hot metal dunked into it. Good little experiment.
Colour is misleading in sunlight, probably should have heated it a bit more past non magnetic but the untempered sample shattered pretty good. I figured risking the glass exploding was worth it to see the bubbles, if it had exploded I might have regretted that idea.
No worries mate, I've done experiments myself mainly on spring steel. Oil and harden it first and keep some heat in the struck end then let the temp colours run to end and quench, works all the time for me.
I was making a knife from a harrow spring the other night had my tank of water heated up nicely i quenched the blade edge and it cracked about a half inch into the blade what did i do wrong would this be less likely to happen with oil
Oil is generally safer than water as it gives a slower quench, sometimes mystery steel has microfractures in it already and it will crack regardless of what you quench it in. Getting the steel to the right temperature right can be tricky too.
wrong.apply heat from struck end so shank is annealed and flexible while the tip is hard to cut with and keep an edge.smack a pice of spring steel quenched without any hardness removed from the shank.wear goggles!!
flame temper rather than oven temper? this was a pretty quick dirty test but I was surprised how much hardness was lost from the oven temper, will try flame tempering or just measuring oven temperature next time, i'm planning on making things much too long to fit in an oven so flame/direct heat will be the way to go. Might even try a heatgun.
Nice forge 👍 dam now I have to find two rims. That was cool to see the hot steel in the jars. A little risky though 🇨🇦🥓🍻

Very good bro👌🏼👌🏼👍🏼👍🏼
Cheers!
Very nice 👍
Thanks!
What is the device on the middle of the grinder? The black box with the stacked discs in it.
It's for dressing the stone wheel that I replaced with the wire wheel on the left side of the grinder
Nice video
Thanks!
It's a spring steel being a STEEL either 6150 ,5160 or something else should harden

Is it meant that toughness is same with water or oil temper?
Not really, much higher chance of cracking if you get spring steel hot enough and quench in water. This isn't a very good comparison video.
So water made ot harder?
I think so, but I'm pretty sure I overheated the steel so neither was right.

What coal do you use?
Coke I got from a blacksmith workshop.
