"SO easy, a caveman could do it". You'll need a tank for gently boiling H2O (mine is stainless), and a heat source to get the H2O gently boiling (probably a tank stand so you're not working on the floor), a carding brush or wheel (a motor to turn the wheel if you go that way), 0000 steel wool, degreaser, the rust bluing solution, wire to hang your parts from and, I like to suspend the blued parts in H2O displacing oil for 24 hours after I've achieved the desired color, so, you'll need another tank and water displacing oil. Oh,,,, you'll also need to polish all the metal and the results will depend heavily on how good you're polishing is. And, 3 to 5 hours for the bluing process (polishing time not included). (There are only half a dozen ways I can think of, right off hand, that you might screw up!) Or , you might use the "damp box method". That can take up to a couple of days (not including polishing time). Seems this thread really belongs under "Gunsmithing".
