Touch hole liner

[Crow#21957]

Ok I'm starting on a flint lock. I know where the touch hole should be but where the threads on the liner will be in corresponding to breech face. Looks like every what the diameter of the liner is the half that distance in front if the breechplug face is where the hole needs drilled and tapped. Far as vertical I will put it at the sunset position. So am I correct on distance infront if BP face?

Looks like to me the liners center needs to be half it's diameter infrint of the BP face to keep from drilling into the BP faces threads

That is the way I do it + a few thousands as I never seem to get it perfect.

I do mark the position of the barrel base, front of tge plug so I make sure pan postion is right when inletting. But pull the plug when drilling the liner

A liner isn’t necessary unless you just want one. And drilling the vent hole is one of the last things to do on a build after the barrel and lock are fitted.

If the barrel has a straight tang, and is straight sided you can inlet the barrel slightly rearward to mine the breech face back enough to accommodate the touch hole liner ( so it lines up center of the pan)
Or, you can do this to the breech face.
