White Lightning liner
« on: July 09, 2016, 10:41:55 PM »
Hello Gentlemen,
I installed a WL liner and not thinking about stainless steel vs. soft gun barrel steel tightened the liner expecting it to tighten when it made contact with the barrel. When I realized my mustake I had turned it a couple turns after it seated in the countersunk barrel. I cut off excess, peened and filed flush and it came out beautiful. My question is being that I gave it the extra turns should I worry about this liner blowing out? Thanks in advance for any and all responses.

What did you turn it with? Have you cheeked inside the breech to see what has come through and removed any excess there?  I am not sure I quite follow what you think may have happened? there are severa threads fully engaged, right?

I haven't removed the plug yet to see how much if any of the liner came through. Felt down the barrel with a ramrod and doesnt feel like any came through so yes there are plenty of engaged threads. My concern is that possibly threads would strip out like when a wood screw is over tightened and becomes stripped out.

I have found the whitelightning liners to be pretty soft.  I think they are softer than most currently made barrels.  I would not be comfortable leaving one that had been seriously over tightened.  They are not expensive.  I would remove it and try again.  Once the bevel contacts the countersink, a quarter turn is about all it takes.  I find a pair of vice grip pliers cut deeply into the extension.  This is why I think it I soft.  More knowledgeable folks will chime in  and have good advice.

I have always been kind of spooked about tightening those super fine threads myself. Usually I turn the liner in to make contact and then tighten down MAYBE a quarter turn more. If you turned it two turns it is very possible something may have stripped. I would definitely remove it and see what is going on. Incidentally, these things should be installed without the breech plug in place so that you can see what is going on.

i wouldn't install any new touch hole liner without first removing the breech plug, IF the breech plug can be removed. 

this has never been a problem for me with a traditional breech plug - i use a rice breech wrench and rice octo vise plates. 

this CAN be a real problem for most of those production patent breeches, like traditions and cva (they are practically welded on and the manufacturers advise that attempting to remove will bugger the barrel), and add in pedersoli.  investarms (lyman, dgw and the like) can be removed with a good flat jawed wrench (reed rcorp) and a heavy bench vise.

also, all liners and plugs go back with anti-seize lube.
