Thanks for your comments guys, A new vid will be up soon with more detail and a few tempering techniques.

where can i get a torch like that

Hi I got this one from e-Bay.

Hello, this hardens the steel to give it a more durable edge, when you heat the steel to 800 deg c it straightens all the molecules in the steel and aligns them. The purpose of the quench is to "freeze this stronger state for the particular temperature" so in affect you freeze the steel at that moment in time. it is then tempered to make it a little more flexible, if it was left rock hard it could break or shatter.

what is the purpose of heat treating and quenching a steel?

@9ineaxis2010 the point I was making was the statement that "you want to use oil and not water because water will spit everywhere and not give you a good quench" was inaccurate. The reason you don't want to use water is that for most "oil hardening" steels, water will be too much of a shock to the steel and cause it to crack. It has nothing to do with it spitting and not giving a good quench.

@Evilrolfharris - that's why you can use oil, or a polymer quench :)

learned more from you in 4 mins that most of the other heat treating vids that where 30 mins...thank you man

[Evilrolfharris]

the problem with water is it will give you TOO good a quench for some steels and that shocks the steel too much and causes it to crack.

I use clean engine oil, but I have also used cooking oil before, i notice no difference between the two except the smell, just don't use water, a cheap can of engine oil is probably your best bet.

[youdontsaythat09]

what type of oil?

[scottishbushcrafter]

It is possible to quench in water. It depends on the metal. But a good vid none the less. Thanks

Great job on the video bro! Comprehensive, and to the point! Thanks for the idea on the forge too!
