In the Model 60 thread in the rimfire area, Spud9 pointed me to this video for re-blueing. Have a look.

If you are doing the whole barrel, check out this video. There is some prep work at turning the barrel in a lathe, preferably and getting a long enough trough to warm the barrel in water (heats more evenly). But all in all, real simple.
