wow. looks great! can you give some more information on the salt bath process?
Well bluing (salt bath) process itself is not at all difficult especially for pistols. Can be easily accomplished at home/garage without any special equipment assuming you already have the salts/bluing solution.
Take a stainless or black iron pot wide enough to fit your frame and slide and at least 1-1.5 gal of salts with some room to spare.
Following steps need to be done in well ventilated area.
-Bring solution to a boil or near boil (it's around 255-265 F). Having thermometer wouldn't be a bad idea. Take note that salts from various sources might blue at slightly different temperature, just follow manufacturer's instructions for proper temp.
-obviously strip, degrease surface prior to bluing.
-make hooks out of steel wire and hang your large parts one by one suspended in the solution by means of stick across the pot/tank, without having them touching.
-Don't let them sit on the bottom though. If bluing in less than 2gal of solution, then allow solution to return to bluing temp between slide and frame. -For small parts use stainless steel mesh basket/sieve/strainer.
-bluing usually takes 20-30 minutes. Depending on brand of salts, maybe more or less, just follow manufacturer's instructions.
-make sure you keeping solution temp steady otherwise you either plum your parts or loose solution too fast and risk soot fall-out or solution burn-out.
-once bluing is done, take parts out and thoroughly rinse-out salts in very hot water (5-10 minutes).
-dry (compressed air is best) but towels/rags would do too. hot water from step above should make it fairly easy.
-now oiling and reassembly, might take a lot of rubbing-in, almost as long as entire prep and bluing.
That's all.
