Good idea- but maybe After you finish all the drum reworking?
Personally I'm happy with a shooter that is not refinished, maybe even prefer one that way; but-
many folks do like their pistol to look "nice" and pretty.
Getting the surface prep correct for "just" a dip hot blue will be near impossible, you really have to do more than an acid dip to get a reasonably even hot blue finish- I know from experience as I blued a lot of firearms in the 1970s. I did it for extra money and I needed $$ then- but now you could not pay me enough money to go into "bluing" of any type!!! JMHO.
