How to blue a tang?

After several attempts to reblue some tangs without actual blue, I figured it was time to bite the bullet, and just buy the darned stuff already. I saw some modern razors with blueing, and realized just how terrible my home brewed attempts were coming out. So then I remembered a thread where a guy had taken pictures of each step of how he did it, etc. But I can't find the thread.

So here I am...Blue Magic in hand...waiting for advice. :p

If anybody can get me that link, I'd be ever grateful. Or if someone just has pics of the process, and can share them, that'd work too.

Also, I need a resist. Any tried and true suggestions?

ive been meaning to do a couple my self also , ive experimented using " Perma Blue " for guns .. i did a tang with a q-tip and results were uneven and didnt look the way i wanted or expected .. i ended up dipping the blade in the container and results were great (dark blue/black) and worked great .. so i imagine once i get going and un pin the blades i wanna do that is how ill do it .. i havent tried to use a rag or anything else though to apply the chemical , that may work also ..

btw i did my little experiments with a unmarked blade that came with a razor i wanted so if i messed it up i wouldnt be out anything ..

Burchwood Casey bluing solution works great.
You can google how to do the process , but in general dip, wipe, #0000 steel wool then dip again, wipe , oil wipe.
The bluing gets deeper when you apply the bluing solution more times.

Just a warning. The blade must be absolutely clean and dry. Use acetone to remove all oils before putting lacquer, paint, or tape onto the blade to make a clean line / mask where the blue is to stop. Do not touch the surface to be blued,
The acid is a water solution and gives off some fumes. It is a good idea to cover the blade in a plastic bag also and tape it above the cut off line of the blue so that it does not get splashed or discolored.
YMMV but not much!

One more little hint,, Warm the steel, a blowdryer or heat gun on low works well,,, WARM not hot, the bluing will take better

Read the part above about Fingerprints again, I use Nitrile gloves any more when Bluing...
