You'd have to build a rusting box. Basically a wood box with a pan of water and a light bulb for heat.

That looks nice, how would one go about doing that process. In my other hobbies, Ive always like that over blinged out chrome.
If it was me sorry if I made it seem like I didn't want it posted. I think gun goddess is great. seeing these I kick myself for not trying it. your results are great. did you card by hand or with a wheel? you did good. build a small blueing box or big one?
as far as areas you don't want blued, I think you can try lacquor on those areas. I know that some guys will lacquor the inside of the barrel (not necessarily the best thing to do) and it must not interfere with the boiling off.
Man, I've got to get out and try this now. 320grit is standard for gun rust bluing. I think I'll start there. but I sent all my blades out, damnit, have to find something to blue now.

Electrical Tape will do a fine job masking areas you'd like untreated. Yes, even through boiling!:)
Careful with slow acting processes which could possibly cause pitting.
You need to buy bluing solution from either Half Moon Rifles (what I got, you can find it on google, you'll have to call, then mail a check) or from some place like Brownells. They'll send you a booklet with instructions. Basically you sand, degrease, apply solution, rust, boil, card, repeat the last four.
No worries, I thought I might be reading too much into your post, but I figured I'd err on the side of caution. Thanks for hooking me up with the stuff.
I carded the first three times with the fine buffing wheel of a underpowered cordless dremel set on its lowest setting. The last 2-3 cardings I used steel wool soaked in alcohol. The buffing wheel had a little bit of bite, so I figured it was good for the earlier cardings, and the steel wool seemed to leave a finer finish. Where I live we have 90% humidity on a good day, so I didn't need a rust box. As a matter of fact, I did them inside b/c I was worried about too much rusting.
Yeah, I think I'm going to try lacquer (maybe nail polish). I'll also try Kevins idea (thanks Kevin) with the electrical tape. I think that maybe getting a straight line on the spine may not be all that hard in some cases. If you just make sure the blue goes into the hone wear area then you can just hone w/o tape, and that should get rid of the bluing and give you an even line on the spine. In theory, at least.
So far, I've actually liked rust bluing stuff, myself. Its really not all that much of a hassle and you get really nice results.
