doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Epoxy Repair Barrel Pits?

I have been reading with interest the discussion about barrel damage (when on the subject). I have several SxS's that are pitted to varying degrees.

I have also been looking at a number of advanced epoxy products that have been developed for industry metal repairs, most have high temperature tolerance and are machinable.

A barrel could be "super cleaned" of all rust and oils etc. by electrolysis or other means then coated with a pore filling coat of epoxy.
The tubes could then be honed straight thus leaving the pores and pits filled. I figure plastic wads will pass over the repairs without damage.

I think I will try this sometime......

Interested in hearing your results if you do give it a try. Although I'm not up on epoxy technology, I had the same thoughts a few years back, but didn't really pursue the idea to determine feasibility.

If I were to try this I would look closely at an industrial epoxy called Belzona. It is unbelievably strong and long lasting, can be machined, and is used in the repair of cracked engine blocks and many other "salvage" repairs to steel. One caveat, it's not inexpensive.

Good luck. SRH

"Expensive"?? yup- Stan, in my experiences in welding and machining ferrous metals, the best products and techniques (TIG-Plasma) always are- ?? is- is the material cost of the filler rod-flux, whatever justified by the results you desire.??

I have one basic SMAW rod I use for welding both 300 and 400 Stainless steels, also stainless to fabrication grades of mild steel, - I use Lincoln 308-16ELC in the smaller dias; and also that rod as a bare filler rod for TIG (aluminum, that's a whole 'nother ball game, isn't it.?

Now as to this filler product you mentioned as being used on cracked engine blocks- does it work on aluminum blocks with lined cylinders, as well as on cast iron blocks?? Just curious, as those differing metallurgical items may require a slightly different filler material??

Anyway, Mae and I are so glad you have bounced back from your near brush with the Grimster- Christmas best to you, Jean and all the Hillis clan down in Deep Dixie-- RWTF

Not sure about aluminum. The link to the website should take you to enough infomation to satisfy that question, but I think the answer is "yes".

Thanks for your concern, and Merry CHRISTmas from the Deep South.

Another crAzy thread...

jOe, don be ah grinch...

Most epoxy breaks down at temperatures under 300 degrees F.
Even the best high temperature epoxies break down at around 600 degrees F. These temps are considerably less than hot powder gasses, and most pitting tends to occur back where powder gasses are hottest. Even though the duration of extremely high temp is very short, I'm quite certain the combination of temperature and pressure would quickly erode your thin epoxy veneer.

There's a reason gun makers use steel to make gun barrels. You are expecting epoxy to do something it was never intended or designed to do.

Keith, I agree it's asking epoxy to do something it was never designed to do, but since no money is riding on this discussion let's pursue it a bit for kicks and giggles.

Belzona 1511 will withstand a sustained temp of up to 392 degrees Fahrenheit. Even though the flame and gases reach much higher temps, it is only for a microsecond. That's the reason it takes repeated shots in a short time to heat up the metal.

Is it possible that the epoxy would never reach 392 itself?

And, is it not also true that the heat shielding tiles are held on the space shuttle with epoxy. They get glowing red on reentry.

Is the goal to shoot or beat someone at a gun show? Turkey to treasure in one easy smear?

bill

bill,
I had not considered that aspect, good point! I just shoot'em.

To all the other comments, I suppose too much time thinking while setting feeding.

Stan, I had looked into the temperature range of Belzona, I would like to find some data pertaining to powder burn and such.
Do you happen to have NASA's phone number?

I have used Belzona on many occasions repairing blast areas of guided missile launchers. this is what we used to fill in between the ablative tiles that protect the deck and blast doors and plenums its quite a job to cut out and replace after a shot. getting the bottom of the pits clean enough to make a good bond will be challenging . The Navy uses Belzona to reline centrifugal pumps when pitting becomes a problem. good luck and I am looking forward to see your results

Sorry Mike. All my contacts at NASA have retired.

Stan,
Ablative tile keeps the heat from transferring to the shuttle, it glows red in one side and can be touched on the other. Yes, glued in place.
The problem I see is you are going to have different expansion rates between steel and epoxy. That would be the end of the epoxy, along with the heat itself.
The differing expansion rate between materials is probably why nobody has successfully developed a plating process to restore old barrels.

Best,
Ted

Thanks, Ted, but I'm not going to try this. I don't want to steal AZMike's thunder.

I just suggested the Belzona only because it is the best epoxy for steel repairs that I know of, and because I just enjoy thinking outside the box.

Best, SRH

If that's a big issue, how does Belzona work so well on engine blocks, etc., in industrial applications where expansion of steel is a fact of life? I know personally of a tractor engine that has been running for several years with it in place.

I would guess the tractor in question has a cooling system, likely liquid cooling, that keeps the expansion in the repaired area under control.

I wouldn�t bet heavily on a repair in a combustion chamber, exhaust port, or turbo housing.

Best,
Ted

I'll bet the company has thought about heat expansion of the base metal.

SRH

Cold Iron is the Naval Engineering term for the ships plant being shutdown and hotel services are being received from the pier. Meaning you are not out to sea anymore. I've been using that handle since I retired from the Navy 25 years ago. As a propulsion engineer.

Been doing computer systems since 1976 also with APL my first language and have been doing only IT for the last quarter century so have no idea where Belzona stands now as far as composition and application or if it has even changed. But at one time I earned the nick name Belzona King I was pretty damn good with it. And yes did repair a lot of pumps with it when out to sea with limited resources. Belzona was (and is) expensive so I kept it under lock and key.

If flanges allowed would weld and build up the metal then file and shape it back down to mate surfaces. Pump shafts, impellers etc. are different alloys and shapes and don't always allow that luxury. Belzona to the rescue. Would not use it on a 975� 1200 psi system if I could help it. But was always amazed at how well it worked no matter what the application was.

Not sure I would be brave enough to use it on a gun barrel though. I too am looking forward to the results.

I wasn't trying to rain on anyone's parade Stan. I was merely giving my opinion from the perspective of a lifetime of fixing things, and my knowledge and experience with epoxies. I'm glad Ted mentioned the thermal insulating properties of the space shuttle thermal tiles.

I'm also glad you provided the temperature and pressure tolerance data on the Belzona epoxy, which I have never used. You will note that the pressures are well below what would be encountered in the rear portion of a shotgun barrel, even though the duration would be as brief as the temperature extremes of hot powder gasses. Then you also have the added component of friction from the shot column and wad moving across your epoxy repair at 1000 fps or more, and powder residue from previous shots scoring the epoxy, which is much softer than steel. You would not encounter this in any centrifugal pump, and even those temporary repairs are not intended to equal normal pump life expectancy.

I also considered the repeated thermal expansion and contraction, and the very real possibility of separation or delamination causing a partial barrel obstruction, and resulting in a bulge or burst. Of couse, if that happened, we could always have one of those fun entertaining barrel burst analysis Threads!

Even if this experiment worked OK in the beginning, would you want to be the unsuspecting buyer of this gun several years down the road.. not knowing that you'd better check the bores after each and every shot??? And that brings me to the same thought I share with Bill Shodlatz. How many unscrupulous individuals might try to do a Bondo job on pitted barrels to sell a gun that has questionable pitted barrels?

At work, we are constantly tossing out and debating ideas. Many are shot down after a little debate and consideration of the ramifications. Some sound very good on paper, but are not at all good in practice. Some end up creating worse problems that they were intended to solve, and some are downright dangerous. Then we have the winners that make us keep trying. I think this idea is just dangerous, and best shelved permanently. In the final analysis, many guys simply worry way too much about minor pits that look much worse than they are. And some barrels reach a point where they need to be removed from service.

Forums are the table at McDonalds where the old guys get together to bull shit in the mornings.
I have an 1882 Remington with pits in the steel barrels, if I can afford the epoxy I'll try 1 barrel with gunsmith Rick Dunbar's help and very careful shooting and checking.
I have no intent to dupe anyone, that's not the way I roll.
Thanks all for the thoughts and ideas (over coffee)!

Yep, it's fun discussing stuff like this. I have grave doubts about the efficacy of this type "repair" but if Mike's willing to give it a go I'm all ears as to the results.

I doubt if Mike, or anyone else here, would try to salvage, in this way, a barrel that was deemed unsafe because of extreme pitting. I certainly wouldn't. If it were to last for any considerable length of time it might spark an idea for a repair on something else one day down the road, that we would never have thought of otherwise.

If it doesn't last indefinitely it doesn't mean the idea was a failure. It just means that potential method/product has been eliminated by actual trial. That's often how useful discoveries happen.

SRH

az, let us no watt appens...

This is just so much fun....

This has got to be just about the silliest crAp I've ever read on the internet.

Stanleys Belzoni Balogna epOxy.

And ole E D chopping at the heels to see if it'll work to go along with his torch jobs.

Fire an E'poxy don't mix...

There seem to be a host of high temp cements, epoxies, and various other coatings that may very well fill in pits. Some of them may be more costly than a new gun I suppose, but perhaps several have some utility for this purpose.

Didn�t Teague stop putting liners into barrels because they had problems with the adhesive system? Not clear if the problem was as getting an even, end to end coverage, for and barrel and liner or was it the bond broke down over time? It would be interesting to try pit repair as described above. What do you really have to lose?

jOe's approval?

Winchester brought out the Model 59 shotgun in 1959. It had a fiberglass wrapped barrel. I am not too sure how it relates to this subject but I'm pretty sure a jam-o-matic can get hot!

This article doesn't say the adhesive was the main problem. Other issues like repairing barrels with the liners were a problem along with some reviling with the liners. I wonder what adhesive was used for the liners. Teague Liner issues

Ken

Wrong thread

I doubt any epoxy finely enough applied Would stay stuck to a pit The strain of the barrel as it bulges during firing Would probably pop it all loose in short order

Yes, with a steel liner taking the brunt of hot powder gasses, pressure, friction, etc. There are also rifles using a similar system with a rifled liner wrapped in carbon fiber and high temp resin. This is like the difference between using epoxy to patch an engine block because the water jacket leaked, and trying to use the same product to line a scored cylinder.

KY Jon asks what you have to lose??? If the veneer of epoxy pops loose and creates an obstruction in a barrel already somewhat compromised by pitting, you could lose digits or an eye. A lot of dangerous experimentation has taught us about things like the strength of Damascus barrels. But when the risk became greater, the firing was done with a string pulling the trigger, and the shooter shielded behind a protective barrier or a big tree.

I think that the eventual failure probably won't result in a barrel burst, but the possibility certainly is there. Most likely though, you would simply learn that an epoxy interior surface is simply not up to the task, and it will never be a satisfactory replacement for sound steel in this particular application.

I figured Steve'O (SKB) would pipe in after all he was the American connection to Teague barrel liners at one time...at least she said he was.

I took a model Winchester Model 59 to Columbia for doves countless years ago. No problems but the epoxy holding the ramp and front bead failed after the first day.

I think the idea has some merit. I spent my career in the aerospace service industry and was tasked with finding safe and economical repairs due to design issues, corrosion, failures, etc.
I wouldn�t dismiss the possibility of using some of the latest super epoxies or other products that have come out in just the past few years.
I have also thought of repair ideas that might be used to repair barrel corrosion and pitting.
We repaired some high dollar landing gear struts that had internal corrosion by machining the internal barrel of the strut and have the barrel chromed. Could this be done on a shotgun barrel? I�m not sure.

Could a thin metal sleeve be hydroformed inside the barrel after back boring? Not sure.
Could a barrel be back bored and then heat the barrel in an oven, super cool the sleeve using methanol and dry ice then press the sleeve in for a interference fit? No bonding agent needed possibly eliminating the issues Teague experienced.
Wouldn�t resolve the issue of making a dent non repairable but if you had a unserviceable barrel to begin with you got more time out of the barrel then you would have in the pitted state you are ahead of the game.

I guess Steve swore an oath of Teague Silence...

Did you have a question that was not covered in Dig's article? I am happy to share what I know about Teague liners and have done so in the past.

I've always thought chrome lining might be a solution to this problem. I don't know much about the process. If it was feasible it would already, probably, be being done. Any thoughts ?

Sure. Hard chrome plating the inside of pitted shotgun bores would involve first machining out the pitting, as was done in the case of the high dollar aircraft struts mentioned above. You cannot fill in pits with plating, and get a smooth surface. Then the bores would be nickel plated, followed by a hard chrome plating of not more than .005". Going any thicker would lead to problems with the chrome surface, which is much more brittle than steel. I can't imagine that .003" to .005" of chrome plating will make the barrels any stronger, especially if you honed out that much or more prior to plating them.

I have no idea how this would be accomplished on an intact set of double shotgun barrels, i.e., how this could be done without plating the outside or affecting rib solder joints, etc. This may have been economically viable on high dollar aircraft struts, to prevent future internal corrosion, but likely wouldn't make any sense whatsoever on a set of old pitted shotgun barrels, unless the gun was rare and very valuable. Anyone want to speculate what sort of valuation hit a Parker A-1 Special or Lefever Optimus grade would take if you chrome lined the bores???

The idea that any currently available epoxy as a bore lining would have merit would be quickly dashed by simply taking a sample of the epoxy and comparing the surface hardness to the hardness of typical shotgun barrel steel. Then compare all of the other attributes of steel that make it the universal choice for gun barrels. It is wishful thinking to believe that an epoxy lined bore in a shotgun barrel would last, given the temperatures, pressures, and friction involved. Even when these materials are used to repair pitted surfaces in a cavitating centrifugal pump, for example, the repair is regarded as a temporary fix until a replacement can be acquired.

If I'm going to dream about something, I'll dream about winning the Powerball Lottery Jackpot, and then buying a really nice shotgun without pitted barrels.

There was an outfix in Charlestown, IL that crome plates barrel i.d."s. The first coat was copper to provide a base for the chrome to stick to. Perhaps that base coat could be applied heavy and the hone to hid the pits?

bill

I couldn�t care less about a pitted barrel unless they�re extreme. Small ones have virtually no weakening effect on strength or performance. With proper cleaning, modern powders, primers, and plastic shot cups pits are not going to grow. When buying a real vintage gun I tend to run backward (long experience) when a seller says the bores are perfect without a single blemish. Bells ring all over and I hear �honed�! Now I have to worry about wall thickness, quality of honing, and all sorts of stuff. Give me a frosted barrel anytime over a perfect bore.

watt joe said...

The only currently available technique I hold out hope for is some form of spray welding to restore the barrel's interior to solid, uniform steel.

Tubing/sleeving into the breech of a gun is very viable, esp. with TIG welding. But, properly done, it isn't inexpensive. There is a fairly broad range of guns that can get a "second run" via this technique at a reasonable return on the cost. Bottom of the heap guns are best consigned to a comfortable place on a wall or over the mantle. Top of the heap guns should have new barrels, spankin' new from a time served barrel maker.

Chrome plating is common for extra runs of aircraft engine cylinders. I don't discount an adaptation to gun barrel repair.

DDA

I know of no currently available spray welding process that could be used inside even an 8 gauge bore. 12 gauge or smaller would be out of the question. I've seen a couple different spray welding processes in use, and the size of the equipment, and the requirement that the arc or plasma spray be applied perpendicular to the surface being repaired, would preclude filling even one pit inside a barrel, let alone lining and restoring an entire bore.

Spray welding isn't even used to build up and resurface worn out ways on lathes, because it will delaminate at the thin edges when surface ground or scraped. The molten metal droplets spread out and stick to the surface, and to each other. But there is not the same type of fusion to the base metal as in other welding processes where the base metal is actually melted.

Then there is the little problem of the heat generated during the process. Even the lower temperature arc and combustible gas processes would heat the barrels hotter than the melting point of the solder used to join double barrels. The plasma spray process, which would give much better adhesion and a more uniform surface, is much hotter than that.

Maybe someone will someday miniaturize spray welding equipment to the point that it could fit inside a long small diameter tube such as a shotgun barrel. And maybe someone will also develop a process to inexpensively 3-D print a new set of barrels that would perform safely. Right now, both ideas are nothing more than dreams in the distant future.

I have brought this posting to the top after Keith’s disparaging remark about me stating I would be using epoxy on a pitted barrel and reporting back on the results.
Please read through this complete posting and determine for yourself if I ever stated this.
I as well as others were throwing around ideas as far as possible solutions to addressing barrel pitting and possible repairs.
This is something that should be encouraged, the sharing of ideas and healthy conversations between reasonable members.
Keith throwing out disparaging remarks especially ones that are not true or incorrect is something taken from the Liberals play book that you Keith, regularly voice your position against.
Your attempt to discredit me publicly and your on going unprofessional nasty comments about others overshadow any good knowledge you are able to share.
Although it allows you to vent it does not add any value to this forum.
It simply creates hate, discontent and makes you appear to just be a grumpy old man that is miserable with life and is determined to try and tear down others, ruin their day, and trying to beat them down with your labeling and name calling.
This internet bullying takes away from this forum and discourages many from posting.
I know that posting these comments drive you to take offense and spend hours researching my history to try and find something to beat me up with a discredit me.
Don’t waste your energy. It will only confirm my earlier statements.
Too many good people no longer contribute to this forum due to your personal attacks.
You are clearly a bright individual with plenty of knowledge to share but many don’t appreciate this knowledge due to the hate and negativity you bring to the forum.
I’m voicing what many feel but are hesitant to state as they don’t want you to put them on your personal attack list.
Feel free to PM me with your contact information and we can have discuss this further rather than on this public forum.

There is an old saying- if you throw a rock at a pack of dogs, the dog that gets hit, will be the first dog to bark. Meaning, the person who usually does the accusing of people doing something wrong, is usually the person who is the problem. You remember when the teacher used to say, "Okay, who did this?" It was usually the guilty child who screams, "It wasn't me!" So who do you think would be the first person on this board to be the one who is anti-gun. And a Joe Biden lover. You got it! It would be Kieth. Is he even a gun owner? Has he ever even posted a picture of a gun he owned? Yet he is always accusing people of being a liar when they say they bought a gun. Like SKB asked- has he ever posted any work that he has done? I talked to several people who are expert in their field and when I posted it, Kieth calls them liars. That is why I keep him where he belongs - on IGNORE. I get emails from people telling me how enraged he gets at me. It is hilarious. It is so easy to do. Ignore him. I love it when someone says that he is calling me a liar and saying I'm stupid. 😁

Spot on WRT "keith."

He's a cancer, and something should be done.

I haven't read all the posts, but I have thought about this before and considered how you would cover it up. Bluing probably wouldn't work? Paint?

I'd suggest you start a new Thread to pose your question concerning a good finish on pitted SxS barrels refined with epoxy.

I'm sure the brain-trust of Ghostrider, DimmyW, and TransGomer Joff will offer some great thoughts that will only enhance the archive of accumulated knowledge here.

Afterwards, there may not be any solutions, but we could give participation awards to all who contributed.

I can't read the post above me because I have them on IGNORE. From what I am reading, the blast from a shotgun blast can reach a temperature of 1000 degrees. For me it would be easier to just line the barrels. Or maybe get inserts. But the gun would have to be awfully special for me to even fool with it.

DimmyW, if you really had me on IGNORE, you wouldn't even know I had made a Post. There would be nothing to see, and no notification that someone you were IGNORING had submitted a Post.

It works the same way for Ted and everyone else you are pretending to IGNORE. This is worse than TransGomer Joff proclaiming he cannot possibly be triggered. Actually, he is like a set trigger set so light, a mosquito fart could release it.

So let me offer a suggestion that will help you get your AutoZone Exhaust and Muffler Epoxy inside a shotgun barrel:

First, you must remove it from the packaging. That will help a lot. Then you will have to open the tubes and mix it at the correct ratio of resin to hardener. Then you can use a cleaning rod and a swab or patch to apply the mixed epoxy in your bores.

You should probably do this as a preventive measure, even if you don't have any pits in your barrels. If you use a heavy enough coat, or multiple coats, you may be able to increase the value of your guns by turning 12 ga. guns into 16, 20, or even 28 gauge guns. Be careful, this isn't that paste you ate all through school. Do not eat it!

I certainly do not wish to discourage this sort of experimentation, because others have said I shouldn't... no matter how utterly stupid or dangerous it might be.


Please let me know how this works out the next time you pretend you are IGNORING me. Good luck.

No reason to read it, it's just the board cancer trolling.

More trolling from the board cancer.

I have personally honed over 75 Shotgun barrels both Damascus and fluid steel. Some had pits as deep as 11 thousandths which were removed. Will they sometimes be considered out of proof? Sure, but they can still be saved and made usable. I start with 80 grit and end with 1000 grit. Wall thickness gauges are a must. You would be amazed at how many barrels can be honed and still be put back into service safely. But you have to know what you are doing. Most of the shooting value in a Shotgun is in the integrity of the barrels. Epoxy I do not believe is a viable solution.

Keith leave me out of your personal attacks, it took you over a week to get the balls up to try to fire back with your childish comments. You are just a miserable prick that try’s to throw a turd in the punch bowl on every post.
Be quiet little one, this is a site for adults.
By the way you never had the guts to PM me.
I bet you are a little troll living in your mother’s basement, next door to your best friend the Nazi.
We all know your kind, playing a badass behind the keyboard.
It’s clear you don’t have a life, your continual immature attacks are getting old. You try to bully your way on this sight.
Patting yourself on the back with your bullshit yet never posting any pictures of your fantasy guns.
Go away you little boy.
It’s time people that are fed up with your hate and nastiness voice their thoughts of your immature tirades. Many are afraid to be put on your personal attack list. This is why many don't stand up to you. The slithering skill you have honed to put down others, is a weak attempt to make you feel better about yourself.
You are like the little worm that would sit in the back of the classroom in grade school, creating a disturbance to try and get attention.
Most of the members on this forum have figured you out, you try to act like a tough guy but would put you tail between your legs and run if you ever had the misfortune of meeting any of the fine people you stalk, on the street.
Why you have been allowed to stink up this fine site with your festering and putrid infection baffles most of us.
Now go back down into your mother’s basement and try to pretend to be someone.

I will be out hunting turkeys in New Mexico for the next week.
So take your time to respond Keith, or who ever you are this week as I will actually be out using a couple of my fine guns while you hide behind your keyboard fantasizing and trying to make me your next victim. 😝.

For cryin' out loud Ghostrider, you left out the best part. According to the emails I get, kieth is too stupid to figure out how the IGNORE system works. Just like I said before, he's just an anti-gun troll acting like a big time gun owner. Put him on IGNORE like I do and forget it.

Nailed it.

He's nothing but a troll, and why his behavior is allowed is baffling.

I think those of us that are sick of his crap should blow up any topic where he's allowed to behave like that.

Ghostrider, I did in fact respond to you, the very day you had your previous tantrum. But I did it by submitting a Post right here in this Thread. I did not hide behind a PM. I wanted everything I said to appear in public. On the same day, I also responded to Princess Stevie's request for pictures of my work, which he/she Posted in this forum, and in the D.I.Y. Gunsmithing forum.

The Admin., Dave did not Post any of those three Posts. For some unknown reason, he decided to give both you and Princess Stevie a very long standing eight count. I suggest you contact him to get my previous reply. A couple other Posts I made the same day did appear. I honestly didn't think my reply to you (or Princess Stevie) was anything that shouldn't pass muster. Not nearly as vitriolic as yours. And it certainly didn't compare with being called a Nazi or being falsely accused of having a Nazi for a "Best Friend." You Libs love tossing that "N" word around, don't you? But that has been tolerated here for several years on DoubleStandardsShop. So excuse me for not being impressed with your accusations, and acting as if I alone am the "cancer" that is eating Joff's brain.

You sound very upset and highly triggered, and your own little personal attack is impressive (and hypocritical). I have not made you a target. I did make a mistake by confusing you with the OP who said he was going to try the epoxy barrel lining. I admitted that in my reply which was not posted. However, an apology for that is totally off the table after your little rant above. And I also responded to your silly idea that incredibly stupid things like this Epoxy bore lining to repair pits makes for valid discussions.

They don't. They should be immediately shot down because they are not only totally impractical, but potentially dangerous.

Oh, BTW, here you can find photos I previously posted of one gun I own. No need for fantasies. No need to line the bores with epoxy either.
