I’m looking for a gunsmith in the Denver metro area, who could install a White Lightnin' vent liner on my rifle. Anyone have some recommendations?
I kept going, the next thing I knew I had drilled all the way out the other side of the barrel.
There is no way you can trim the bore end of the TH without access. Yes, you can measure, but inspecting and trimming after the installation is best in my opinion.Am I missing something why are you pulling the breach plug?
At first, I would install the liner and use a diamond bit to trim the excess that protruded into the barrel, with my last few I would screw the liner in, mark the excess with a sharpie, take it back out and grind off the excess on a bench grinder and reinstall.
Eric, it is a paradox, but this admission on your part makes all of your advice far more credible to so many people. To err is human... Humility, a sense of humor, asking others and finding solutions impress. Good to see someone helping others this way. Nothing like looking at a workpiece gone wrong and thinking in profanities, "now what ?". SWIt is if you have a drill press, the proper sized drill bit, the odd ball tap and know how to pull a breech plug. If you haven't done any gun work of any kind before I would farm the job out.
I have done a bunch of these installations but still screwed up on my last one, I was drilling my pilot hole first to make sure my liner would be exactly where I wanted it to be. I didn't feel my drill bit break through into the breech so I kept going, the next thing I knew I had drilled all the way out the other side of the barrel.
Concerned, I asked here how much pressure a threaded a 10/32 screw could handle. Zonie here did the math and said it would be 10 times the pressure that I would generate shooting the rifle. I tapped the hole to 10/32 and inserted a screw with red lock-tite to hold it into place and finished the gun.
I figured if TC can get away with the same type of all the way thorough hole in their breeches I could to.
