the blackening Hot bluing #Restoration gun bluing #hot #bluing a knife restoration videos seventeen Metal blackening process black oxide hot bluing a knife
I need to blue my BSA airgun. It's long so I have to make a long boiling tank. Copper would be the easiest with ends soft soldered on. Would this impair the job? Also dies the nitriding not affect the rifling? I was thinking of stoppering the two ends.....
Is this color permanent like compney or removable.. if i color the gun like this and then i used it or do firing on it… so the color will be removing or not?
Don't know what compney is, but bluing makes a layer of oxide (like rust, but much more stable). The main use is as a layer of protection against (red) rust, but it should also be oiled because bluing alone is not impervious to rusting - but it helps a lot. Because it is an oxide layer it can be worn off, sanded down, sandblasted or acid-bathed to expose the raw metal. Thats not something you want to often on presicion parts though, because you would be removing a thin layer of metal each time. Its fairly tough and holds up well on tools, but I expect it would eventually wear though on moving gun parts unless everything is kept well lubricated. You can use other chemicals to cold-blue also if you mainly want the esthetics. thats super easy to do with just a brush after thorough degreasing.

The ratio of ingredients and timing of steps of whole procces is not mentioned so vedio is incomplete
I've tried it and it really works! Great & simple! Good job brother!
Easy to understand

This does not affect the heat treat of the steel?
هل يمكنني استخدام نترات الامونيوم بدل نترات البوتاسيوم
im from Pakistan 🇵🇰 thanks brother very informative video.
I am from india...and there goes the neighourhood

Super simple treathment. Burnt engine oil bath at the end remind me old days.
Steel tongs….???
Hello. Thank you for the tutorial... Just wondering... What is the ratio for ingredients... Thank you
Equally all three kno3 ,wather ,NAOH for example 1000gram,1000gram,1000gram capacity u require
what are these products called?

Where do you get oil that black?
I think he used some kind of industrial oil. My grandfather used to use something similar to lubricate his factory machines back in the day
Used engine oil from car or motorcycle.
It looks like dirty motor oil
Зачем столько лишней работы к чему это?
Don’t use a wire wheel
Why?
İts okey using wire wheel but must be soft one
