    An easy out can be used on such but it ruins the liner and it has to be replaced.
    Look or Track of the wolf or Log Cabin sport shop ect to look at liners. Some are flat and files off flush leaving only the touch hole. Some have a slot or a hex female end.

    I have one liner that I got from Dixie a really long time ago. It came with a slot. I've made a few out of 1/4' Stainless, threaded to 1/4 x 28, and counter sunk inside. A couple I slotted and a few not. Anyway, I've never pulled one. I figure it's the same as one with out a liner, if you screw up, either dribble some 4F through the touch hole or pull the ball.

    I remove them every time. I made an adaptor with a hose on it, thatt screws into the vent hole. Hose into a bottle of soapy water, then pump away. No mess.

    If it has a liner and it was designed to come out, then every time I clean them.

    If the thing is properly designed and installed it should be impossible to remove without destroying it and its unnecessary to remove a liner anyway if the shooter cleans the barrel properly. Unless it has a fouling trap of some sort. I have not used a removable vent liner since I found one of these gas cutting around the threads about 1977. Vent installation against a shoulder to reduce pressure on the liner and eliminate any possible gas cutting. 303 stainless. The #38 (.101") is the drill size for the pilot on the counter bore . The liner is bored just slightly smaller, #40 (.098) perhaps to avoid a fouling trap or the #38 hole in the barrel can be opened a few thousandths to avoid a fouling trap. This liner is designed for FF or FFF powder. It, like a White Lightning, puts the charge within about. .030" of the priming.

    Very few, and I think probably less than .5% of black powder shooters have a lathe and other like tools in our garage.

    Exactly. Foot powered lathes were used in the 19th c.

    Shooters are not gun builders. Shooters have others do their work if its beyond there capability. The question of course is; "do you want it right?"

    And how many costly mistakes are you willing to absorb before you get any good at it. ;-)

    OK point made, so for the 5.96 the liner cost me, it seemed a cheaper alternative to buying 5 grand in machine tools that I don't want or need to enjoy my hobby.
    I just needed a dependable gun that I can do simple repairs on and maintain myself.
    I do cut dovetails with a hack saw and a "safe" file. I don't attempt to cut threads on stainless bar stock....

    That is some nice work. What is the size of the flash hole?

    I misr respectfully disagree.

    As for removing it in the first place, I'll agree it is unnecessary.
    Only legitimate reason I can think of is to replace it when burned out.
    (even arms without a removeable vent liner can burn out the vent eventually.)

    1/16" works well. If you are after best accuracy it will start to degrade if it gets much bigger. Its been tested by the Bevel Brothers and written up in MBs. I have a rifle I did a larger vent and it shoots really well. But it has a Nock breech and shoots a one ounce ball.

    I also use H1 taps and if a die is used an expandable type to keep thread tolerance (slop is another term) to a minimum on pressure bearing parts. People using store bought vent liners and standard taps may have the vent come "adrift" or leak. If you install a vent liner you need to PROOF THE BARREL afterwards with double service charge of powder and two balls to make sure its going to stay in. I recommend you do it with the barrel removed from the stock. I could tell you some scary stories about breech plugs installed by the "barrel" makers. I did pull a breech for what it seems is now my apprentice, a new guild member, to be sure it would not need to be redone AFTER it was in the stock. To my surprise it was about as perfectly breeched as they can be. Some "custom barrels" are tapped 2 or more threads longer than the breech plug. Others with other "issues" allow powder gases and fouling full access to the threads where its impossible to remove and just stays there. When debreeched they may look like the photo. The BORE was clean. They are a lot easier to install that way you know. I have had, over the years, a nipple blow out of a Belgian made DGW rifle about 1965, had a modern drum BREAK off, seen a barrel ( by one the big names in ML barrels) so screwed up in the breeching by the barrel maker and by dovetails cut too deep in the waste of a swamped barrel by the parts assembler that I junked it and installed a new barrel. The more you learn the more finicky you tend to get. Unless, like some ML barrel makers you just don't care.

    I was advised to install mine with Teflon tape, so it can be more easily removed if replacement was needed
