I've been told that on the Colt WC1928 the water jacket has soldered joints thus can not be hot blued. I've been also told by reliable sources to use Brownell Oxynate 7 to blue the gun. Oxynate 7 is used at just below 300 degrees. Will this or will it not soften the solder. I've found a professional bluer that does Hot blue and rust blue (done at under 200 degree) and is more costly and as we'll as what he calls Belguim Blue which is used in oldtime soldiered side by side shotguns.

Really want this to be done right and cost is not really the object.

What say the experts

I'm definitely not an expert on this and do not know about whether the '28 has soldered joints or not. Hopefully someone else can jump in and provide that information. But, if it does have soldered joints - could they be done with a higher temp solder? Maybe silver solder? If so, you would need to deal with the solder not bluing like the steel does. But if the soldering is in inconspicuous places, you might be able to use a higher temp solder that would still allow hot bluing.

Still - it would be good to get some input from someone who has worked with this model gun and knows from experience what works here.

I am beginning to feel like a broken record here. This is the last time I am going to answer this so listen up folks. If you are not going to believe me then fine. Oxinate 7 is what oow's blued gun were done with. Oxinate 7 at 292 deg. will not hurt the gun, its brass, its solder, or its feelings. The brass on the gun will however hurt the salts, so you better count on averaging one 5 gallon bucket of salts per gun. My tank holds 2 buckets and I can do 2 guns before the salts play out.
The endcaps are soldered on with a lead/tin solder. I know this because I have personally removed the endcaps and raised dents from every one I have built before I blued it. When finished I re assembled, and resoldered with the same stuff.
Finally the brass can be polished before, after, or not at all.
If you unsolder endcaps and resolder them, check them for leaks before you blue the gun. This is not a bad idea anyway. The best advice I can give is jump in. Remember the metal prep determines the outcome of the finished gun, more than the type of blue used. Just a general observation though is if the blue process you choose doesnt involve at least some heat, it is not going to be as durable.

This is my full auto 28.

This is it before i blued it

This is an endcap off of the water jacket.

this is a bastardized beater gun with a 28 waterjacket on an izzy backend set up as a 1917a1 for shooting up a stash of crappy yugo ammo.


This is two of my builds side by side. The 28 with the red water plugs has a much higher degree of polish, especially on the sideplates, but the blueing process was identical.


And finally one more pic of my 28 just because I like it.



There are other processes that will work on the 28. These are the processes I used and these are the results. The guns can be finished anyway you please and that is the owners choice. Here is the proof in the meathods I have been describing for quite a while.

Howsabout a nice side view of the highly polished WC? They look SO much better than the everyday parked Brownings....

WOW! very nice Jmann. where do you get the Oxynate7? can you detail a little about your polishing procedure? ..and the blueing process? Thanks. rat

Oh...and yeah, what Shattered said. pleease.
Brownells can help you with the Oxynate7. The polishing is up to you, however. ;)

do a search for his threads in the past. he has gone in to great detail about the great detail that he used with his blueing. i know for sure that i do not have the energy or patience for that, but damn it looks good.

Lucky, thanks. I guess if I'd read the first post better I would have seen the answer before asking. I was too busy drooling on that Colt. Rory, yeah, I guess from Jmann's post I should'a guessed there was more info out there. I'll do a search. ...curious about the reference to dent removal too. I've got a couple of small dings, and wondering how to deal with them, or at all. A blue job like that will certainly make them stand out. I'm planning to build a frankengun along the lines of Jmanns. Lucky, I get up to Waco a few times a year, and would like to take a look at one of your sights if you're still building them. Please send me a pm next time you're heading that way, and maybe I can hook up with you. Thanks everyone, rat

Rat- as one of the longer term members here, you sure haven't been posting much since the board changed a couple of years ago! You should get Dave S to update your post total from the old board.

I try to get out to Waco a couple of times a year. Hope to in the fall, we'll see. I'm stuck in L.A. pretty much these days. I do keep the sights going, just haven't been promoting them much lately. I plan to change that soon. Will be getting a website going eventually. I'll be sure to get in touch when I head to Texas next.
