Double Barrell Blues.

[Gary Patton]

Many winters ago, while being a dumb kid, I was shooting my dad's old Remington double barrell shotgun. Enjoying the hard kick that lets you know you're shooting a twelve gauge, I shot both barrels at the same time. All was great for a few rounds, till the rib that is soldered to the barrels flew off. That was about 20 years ago, and I got to thinking it could probably be fixed with silver solder. Anyone ever done this before? I'm more of a mig/stick welder, and have'nt done much brazing yet.
It would be a good present to fix It back up for him.

yup, but it will need re blued afterward.

I silver solder brass parts for air guns now and then.

I'd recomend building a jig to hold the barrels just like you want them and using a propane or mapp torch with a wide flame and pre heat the whole length up. You probably can't put enough heat to it to get the solder to flow all the way down at once but preaheat it as much as you can and work from the breach to the ends.

you need some more info? just ask.

I'm not a fan of the propane or mapp, I use only Oxy/ Acetylene, and for that you need flux painted on the area of work and silverbrazing rods enough to finish the job, of course...probably 1/16, or 3/32" would do it. When the flux starts to melt, you will then be at brazing temp. Don't dip your rod before then. Keep the heat slightly ahead of the rod in the direction you want to go, and a slight down angle will help there, too. The trick in silverbrazing is knowing when to quit...too much heat, for too long will create porosity and cracks. The metal must be clean, really clean and a hot water soak after brazing will get the flux off. And you will have to re-blue after like dsergison said.

HI GRY PATTON............... I would suggest if your ever going to use the gun again for skeet shooting or hunting........Get it done by a professional...........Thinking safety here a gun smith......... I have one as I think most do.................

If she is a wall hanger and a looker then you could proabably do it. Only other thing is I would remove the fireing pin before I hung it on the wall.........Just incase someone gets overzelous and takes her down to zip off a couple of rounds...........

Be safe.............Rock.....

That rib was most likely originally soldered with 50/50, and you definitely don't want to use silver or brass.
Technicly, the barrels need to be fixtured before soldering the rib back in place, or the pattern will deviate.
We used to make double rifles by soldering barels inside the shotgun barrels, and that job was a MAJOR pain in the ***, to the extent I refuse to ever do another one.
Much sight and rib work today is being done with epoxy rather than soldering because rebluing isn't necessary after the install. The only trick is preglue cleaning, TOP SECRET (place your left hand on the BLUE welder and swear never to divulge this information) Mask it with duct tape and hit it with a sandblaster. Leave the masking in place till the epoxy is thorougly set for easier cleanup.

I think you should get a professionall to do it unless you know exactly what you are doing. If it is going to be fired again just let a pro do it otherwise good look post a pic after your done.

I don't understand all the concern,

soldering two barrels together isn't going to aneal a shotgun barrel, doesn't have anything to do with the action, etc.....

either way the key part is maintaining the proper alignment and still being able to work on the whole thing. you'll need a good clamping jig that will allow you access if you want to solder.

if 50/50 solder is acceptable, great. it's a whole lot easier than silver solder. I use solid wire solder and I clean it off very well. and I like an elictrical flux myself.

If epoxy, even easier still. thanks Franz, I'll take that secret to the grave

Thanks for all the replies guys! I'm gonna go get the gun from my dad, and think real hard on it for a while. I don't know if I want to try the soldering it myself since I would have to re-blue the darn thing. I had'nt considered that, and it turns out, it's a part of the story of how the rib came off. This old shotgun was one of the first double barrells to have hidden hammers, so it was very old and rough when I fist got to start shooting it. I refinised the stock and bought a do-it-yourself blueing kit and spent hours applying coat after coat of the stuff, until it looked awsome! Well, from what I later learned, this ate away at the solder holding it together, making the rib all the more weak.

GARY PATTON.........ask around and confirm it is not a wire twist barrel.........if it is she is in my opinion a wall hanger I am sure I wouldn't shoot it..........Be safe....... and that is my .02 cents worth.....Rock..

No, it's not a damascus twist barrell, it's old, but not that old. I've heard modern ammo is too hot for that type of barrell, even if it has'nt been screwed up by a dumb kid.
