Touch Hole Liner Dangerous?

[misher]

This was on the Caywood Guns website, I've never heard of this before. Anyone see it happen before?



Please be advised that installation of a touch-hole liner will void any and all warranties. We cannot work on a barrel which has a touch-hole liner. The only solution to any problem encountered will be to replace the barrel. Touch-hole liners are unnecessary and they ARE DANGEROUS. After years of use, with gas erosion and replacement-removal wear, the threads will no longer hold the liner in the barrel and it WILL BECOME A PROJECTILE WHICH CAN KILL OR MAIM A BYSTANDER. Your gun will not ignite faster with a touch-hole liner. A properly coned touch-hole will ignite almost instantaneously without any problems that are associated with liners. Please be advised not to stand next to any shooter using a touch-hole liner in any gun.

Sniff----Sniff.

I think I smells me a lawsuit protection stance.

NO. I have only heard it mentioned on this Caywood site. A properly installed liner is going to sit there for the life of the gun, or until the TH burns out from using WAY TOO hot loads. My White Lightning liner, made from Stainless Steel, show no signs of wearing. I have never removed it from the barrel, altho it has a screw-slot to do so.

Any improperly installed liner, or nipple, can become a projectile. My brother's first Percussion rifle saw its nipple head for the hills inside 100 shots- the wrong thread size had been chosen for the nipple- by the vendor! AND, the threads were cut oversized even for the metric thread size used!! He contacted Dixie and finally got an oversized nipple that fit, but he never trusted that gun again. ( GEE! I wonder why?) He has since cannibalized the gun, using the barrel on another project.

Guess I was all ready to start worrying about a problem that does'nt exist, I hate doing that. Got enough real stuff to worry about.

So, what are you going to do if you ever have a problem? Replace a $2 vent liner or replace a $200 barrel? :shocked2: Daaaaaaaaahhhhhhhhhhh :rotf:

Boy, I would love to see a properly tapped hole wear out from over-use. Personally, I don't think it can be done.

I agree just covering their butt. Don't blame them in this day and age. Never seen one blow out and never will. Larry Wv

 

[Tom Compton]

Next he will be saying he won't work on per-suction guns cause removing the nipple is dangerous. BS!

Flint, one of the guys at our club actually had a nipple blow out of the bolster on his CVA Kentuckian, it turned out he was in the habit of removing it at every cleaning, and had worn the threads..no one got hurt..and I agree, Caywood is involved in some kind of CYA...Hank

I think its more than covering one's butt. I think Danny Can't stand the idea of anything produced by Jim Chambers being put in one of his guns. When Jim came out with the White Lightning liners, there was a lot of doubting Thomases within the flintlock world, who said a parabolic cone would not make any difference in ignition time. ( They still try to argue it!) But, customer after customer was intrigued enough to buy one or more liners and try them. They all came back with the same comments:

" IT WORKS!"

They did get faster ignition.

As a result, Jim has sold Thousands of liners and made a nice bit of money over the years doing so. Some of his competitors are STILL Jealous. :shocked2: :barf: :thumbsup:

Dollars to donuts he cross threaded it and damaged the threads in the bolster - that is what caused the problem, not removing the nipple. It is common practice to remove the nipple every time you clean a percussion gun and will not cause a problem if it is screwed back in properly. Cross thread it and you have ruined it and all bets are off. As far as a touch hole liner? Like Paul said, I wouldn't remove one, it won't be a problem.

I had a friend have a whole bolster blow out on one of those guns.

I took the nipple out every time I cleaned my T/C's and when hunting always took the nipple out and poured 3F into the channel under it. Never, ever had any kind of a problem with a nipple not doing its job or coming out of a gun.

 

[Stumpkiller]

I've never made a practice of removing the liners from the guns I've owned that came so equipped. Several had no liners and others had the liner filed flush with the barrel so it couldn't be removed.

Kit Ravenshear once told me a vent liner was a repair item and he wouldn't install one on a new firearm.

I wouldn't be worried about a properly installed one. The glow-plug on a 2-stroke R/C engine uses the same threads (1/4-28) and, as far as I know, is about the only other application for that oddball thread. A two-stroke has 17,000 or so explosions per minute in that little chamber and the plugs need replacing about annually. Pressures are less but the vibration and wear from threading in and out is potentially more.

And there are worse directions to have what amounts to a pressure relief plug directed.

First time I ever heard 1/4X28 thread called oddball. It's about as common as dirt.
Touch hole liners, properly installed, are about as safe as anything related to muzzle loading. Put it in and don't remove it unless it needs replaced when the flash channel gets to big. They were PC on high end new English and French guns. On American guns they were a repair, generally, for an eroded vent. If it makes a difference to you cone the vent on your new build and put in a liner when it eventually erodes.

None of the touch hole liners on "best grade" British guns were removable. They were often made of gold and later platinum (which they called "platina" and used because it was much cheaper than gold was at the time). The comparison to the modern version is strained at best... especially when made of stainless steel. For a hobby that takes such pains with being "pc" (or at least many of its participants do) I have always found this to be very curious.

I agree, either cross-threaded, mismatched threads, or it wasn't tight.

Flashliners are fine, IT's Lawyers that are dangerous, I think they should all be banished to an island, to litigate out the rest of their days!!

 

[denster]

Yes I am aware of how liners were made and of what material in English "Best" guns. The comparison is not a stretch. A liner is a liner whether it is screwed in place or brazed. The point being that liners while seen as a feature on a new British gun. Was not commonly found on a new gun made in the Americas it was however a means of repairing a gun whose vent had become enlarged.

[mmahlock]

I'm hard pressed to understand how a touch hole liner can become projectile. I've never seen one that is fully exposed. All of the liners I've seen are between 30-50% covered by the lock pan. For one of these to be blown out would require sufficient force to shear the liner length wise leaving the remaining part captured under the lock pan. :shocked2: Or it might blow the whole lock off which I sincerely doubt is possible even for one with a single lock bolt. :hmm:
