    You could do screws like that but i wouldn't do a barrel this way you might warp it or alter the hardness of the barrel

    Dead right bro. Its only for small parts and while it is blue it can wear very quickly

    Better to use really gungy waste diesel engine oil for this method, or get some carbon black and heat up used oil and 'top up the carbon' in it. It's not blueing so much as carbon blacking, but works OK for small bits.

    For not-so-gungy oils - heat up the oil, chuck the carbon in and stir (keep a lid handy and watch for a drop of water which will explode the works - very burny!). PPE required...

    Keep the thing covered in protective oil as there isn't a lot of corrosion protection with this method.
