Touch hole liner

[Uncle Alvah]

I intend to have a gunsmith/machinist friend drill/ tap my barrel for the touch hole line.  Aside from the obvious, location, is there anything else I should bring to his attention before he works on it?

[T*O*F]

The obvious is not to install it before the barrel and lock are inlet into the wood, but I assume you already knew that.  The liner will have to be sized to the barrel thickness so that none of it protrudes into the breech area, otherwise your patches will snag on it when you clean the gun.

The liner only needs to be firmly in place, don't over torque it or break off the back end. Be sure none of the liner protrudes into the bore, firing chamber. After drilling the hole put a very light chamfer on it, once the liner is in and it is filed, dressed down, almost level with the side flat lightly peen around the circumference before finish filing it level with the flat.

If it is a White Lighting liner from Jim Chambers it comes with pretty clear installation instructions.

The one I have is not but after checking that out I think it will be.

Actually, I did not, thanks. This is my first build.
I thought once the lateral position for drilling was figured. the hole would simply be centered, up/down, on the width of the flat.

Sometimes locks don't end up where you put the hole.   Just make a mark on the barrel for a reference then drill the hole after inletting the lock.  I usually do the measuring and then make a small punch mark that won't get wiped off.

Alvah, make sure you get your White Lightning liner from Chamber directly. There are other businesses that sell what they call White Lightning liners but they are not made by Chambers and are not quite the same. I got one from another supplier and it fractured on the first shot by the customer. Nice. I was able to redrill and tap to the next largest size without a problem but have made sure to only get them from Jim from then on. I showed the broken liner to Jim a few years ago at Friendship and he said there had been some problems with those liners made by other people.

I'll make a point of that, thanks.

Put some choke tube lube or anti-seize on the threads.

Why?  Once installed and filed flush, it's in there for the duration until it wears out at which could be 20K shots or decades depending on its use.  Then it's drilled out and replaced.

[flinchrocket]

For the same reason you use it on the breech plug,help keep powder residue out of the threads.

TOF, I think it also lets the liner go in smoother and easier, allowing it to seat better. You might be right though, it might not be necessary.  Maybe it is OCD but I always put a tiny bit of never seize on any bolts or any other threads on final assembly. Never have had one rust in the hole or been hard to remove later.

2nd what others have said. Call Jim/Barbie and ask for the correct drill and tap as well as the liner. You wont regret it.

I'll do that, thanks!
