doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Problem with barrels after refinishing

Very true. But if a rib is delaminated and rattling, there's a more than likely chance it will leak, way more'n likely. A leak will bring your attention to the area so you can decide if it's delaminated or just a pinhole.

Kilibru:

You can do the air pressure test and if you are satisfied that the ribs are solid and you wish to stop the solder balls or bead piece from rattling:

Take a syringe and inject linseed oil between the ribs, slightly diluted is best.........then stand in a corner on the muzzle for 24 hours..........then stand on the chamber end for 24 hours.......your loose solder balls or piece of bead should stick to the dried linseed and your barrels should be rattle free....

Clean the void prior to the linseed oil injection with acetone and let dry.

You can buy commercial syringes at Home Depot which will fit your rib hole quite nicely.

It will also protect the void against rust.......this is commonly done on welded aircraft chrome moly fuselages for rust protection and left in the tubing for the life of the aircraft, the holes on aircraft frames are welded shut after adding the linseed. They have used this method on aircraft since about 1915.

Best,

First off, all barrels do not ring like bells. Some do, some don't, but don't think that if they don't something is wrong.
Also as stated some barrels will have voids along the length.
The best way is to take .0015-.002 shim stock, it usually comes about 1/2" wide by 12" long, cut it with ordinary sharp scissors to about a 1/4" and put the cut end on a piece of metal with the flat end of a ball pein or carpenders hammer and draw it between the two to take the burr off.
Try inserting it as you go along each side of the barrels. If it slides in, take note of how far it travels until it stops, and go on till the end.

If it was a pressed in ivory sight, I doubt if it fell through, the hole should have been smaller than the diameter of the bead.

Going to someone else, you can probalby expect to pay up to $600 for re-laying the rib and re-rusting, as the barrels will need to be stripped again.

Good luck and let yus know how you make out.

Actually, I do have one shotgun that rings like a bell, and a few others that ring somewhat, but in a very un-belllike fashion. None go "thunk" which is I think a bad sign.

kilibru:
Genius! Hit it with an air hose, squirt in some linseed oil, jab in some shim stock, follow that with some injected epoxy, wait 24 hours while you chant Hari Krishna, then give it all a good tap to see if things ring like the Bells of St. Mary's and yer done.

Why didn't i think of that!

Best, Kensal

They claimed your bead never existed you really think they are going to admit that they hot blued your barrels ?

I'm pretty humbled that you all would take the time to consider a solution. Too bad I can't say the same for the Company that did the work.

Bead sights ,especially those that are pressed or glued in do come out when barrels are reblacked. They also tend to disintegrate in the boiling water and when being "brushed" off between applications of the blacking chemicals. Although care is taken it is not always possible to remove them without damage and to refit them after wards. I always advise customers that we take no responsibility for non metallic sights when reblacking.
As to the Vibration ,its impossible to pass a serious comment without examination. Is it in fact a "vibration" or a "rattle"?
Try it with the extractors and pins removed.It could be one of several other things , do the barrels ring when tapped? Or are they dull,dose it have a center bead? Etc.

JUst reread yuour original post. One possibility is that there is some loose matter in the rib cavity,thats been there since the gun was made. Held in place by the resin fluxes that were used ,the hot water used in blacking has allowed it to be free and so is now what is commonly refered to as a"devil" because its a devil to get rid of.Usualy a bit of solder. If it was rust then you would get a sound like sand trickeling up and down as you tip the barrel.The guy who blacked it should be able to do some thing about it . Being involved in all aspects of barrel work myself I cannot say its any ones fault if this is the case,I'm afraid to say its just one of those annoying things that life throws at us.

Gunman, I guess I probably could have better described to sound. I removed the extractors and associated parts and when tapped the sound is essentially a buzzing sound at the bore end of the barrels as opposed to a rattle. I'm just trying to gain some knowledge here as I'm on my own. I'll have someone check it out. Lot's of work on the gun up to this point so rather frustrating, but at least I picked up some good knowledge out of the deal.
