  • Looks is the main reason but I do like to think that it does offer some protection as well allthough looking after it with an oily rag is essential.

  • Yes be carefull what you do. bear in mind you temper steel by heating it. the colours change at set temperatures, indead thats the way I use to temper parts. Springs are tempered to blue with most other things not so hot. The plunge does not reset the hardness but holds it where it is. So experiment first and good luck.

  • It needs to be as clean as possible when you start to heat it. Do not touch it with your bare hands, hold it with a wire through the bore. Wipe it down with a clean cotton cloth then heat it as uniformly as possible. Then drop it into the oil. No not touch it with anything when its hot. That patch in the middle looks like you may have touched it with a rag when it was hot. Best of luck next time.

  • @LightningAlan

    Hello,

    What kind of oil do you use?

  • @wakigold Hi, I just use new normal low cost car engine oil. not fully synthetic.

  • Hi,

    Don't know on that one. If you mean a traditional rifle with explosives I would not try. If you mean the knife I would say probably yes but you may upset the tempering of it.

  • bluing is a chemical reaction to steel. You dont heat up metal and stick it in motor oil. Are you shitting me? What a moron. Good way to warp your parts retard!

  • also oil is used to harden the steel even more right? if you heat treat with oil dipping after severe heating?

  • doing this could sofen the barrel so if your using high velocity rounds or steel shot be careful the shot can slice the barrel

  • Nice video. I was wondering though will this change the temper of the steel negativley?

  • looks good really like the brazing marks on the parts. gives it a nice touch

  • @leoisforevercool no its to protect it from rust..

  • What is bluing exactly for? It's only for looks right?

  • Looks absolutely lovely.

    Shame the brazing shows up, maybe model 00002 could be welded to maintain the colouring.
