Remage barrel install using teflon tape

[PRR1957]

Remember some plumbers are better than a bunch of gunsmith’s today.

Finally the gun plumbers get some recognition for their deft skills with a hammer and repurposed kitchen utensils.

They use tape with dope on top.

Are you saying not to use hose clamps for scope rings?

I have used multi layers of pipe tape on loose fitting pipe to make it seal, but have never needed it for a rifle barrel thank goodness

In his book Rifle Accuracy Facts the author, Harold Vaughn wrote extensively of the importance of stability of the action barrel joint, and reported the results of different approaches to this, including using teflon tape, which did not work well in his tests in that application. On the use of teflon tape on threaded bolt shrouds, it has worked in cases where a loose thread fit was shown to be causing inconsistency in accuracy. If someone wants to know the details, they can get a hold of me. If the fit is proper, it gives no advantage, but if it is not, it absolutely can.

Wow. I can't believe you mean a 'looseness' between the action and the barrel.
So once the barrel is tightened or the barrel nut tightened, there remains some 'play'?
At some point I would think that even poor threads, while not desirable, would have the action and barrel secure. When you look inside the threads of an action well not so nice looking. Certainly not Rolex microstella threads, but then that's not needed.
The first three fully inserted threads carry 70% of the load.

I was talking about the shroud, not the barrel.

I misunderstood.
But what is the ‘shroud’? Don’t know the term.

 

[Bill Norris]

The shroud is the housing that contains the cocking piece/indicator on the end of the firing pin.

In this drawing it is called a bolt plug, but shroud is more common.

Plumber for 34 years, finally retired and I can’t get away from the lingo?

 

[DShortt]

Some advocate using drain cleaner in a barrel. I suppose it follows that using plumbing products to correct for sloppy machining would follow.

my plumber told me two things

1. s..it always flows downhill
2. don't bite yer fingernails

Third thing, Payday is on Friday!

Having read this book I thought I might try the teflon tape approach in an attempt to get better results with a barrel that wasn't working very well.
The results were amazing!...............Biggest groups I've ever seen!!

this is true and alot of the reason is poor quality imported pipe. ive been there.

Been retired 22 years now. I supervised PF. They used tape alone on most fittings. When they had a problem they would re-due it with tape and dope. Many many years ago the US was importing a lot of black iron pipe from South Korea. It was so poor that it would ball up when trying to thread it. The company I worked for built rocket motors. We could not live the poor quality pipe and quickly replaced it with domestic. My young neighbor is a licensed PF. I have hired him a couple times to crawl around in my crawl space to make repairs. He uses dope over tape. He told me on one occasion that he has never had a leaker.

 

[DShortt]

Well there ya go. Pipe has threads. Barrels have threads. Threads is threads. What more matters?

A Neurosurgeon comes home from work one day and finds a leak under his sink, he calls a plumber out, and the plumber goes under the sink and twist a couple wrenches for a couple seconds comes out and says that'll be $500. The neurosurgeon says, I'm a neurosurgeon and I don't make that kind of money, the plumber says yeah I didn't make that kind of money when I was a nerosurgeon either.

Best thing I've read in years.

And true.

All the truly best comedy is based in reality, and that's why this is so funny.

 

[urbanrifleman]

Dang fellas.

I think a simple "no" would have been fine.

I will add one thing. Don't paint your tenon threads with cheap enamel.

Karcken thats funny right there for sure
