'Evening,
I'm currently in the process of building a Kentucky Longrifle from a Track of the Wolf Kit. I have some questions regarding installing the breach plug.
The book I am using as reference to build my kit is "The Modern Kentucky Rifle" by RH McCrory. McCrory describes how to drill and tap the breach on the barrel, as well as how to weld together a breach plug. I have a pre-tapped Green Mountain 42", 7/8" octagon barrel, 5/8-18th threads. I have a standard breach plug to match.
On the ToW website, they offer lengthy, detailed instructions on how to fit the plug, including tapping the barrel, cutting the breach to match the plug, as well as modifying the breach plug. (Seen here: http://www.trackofthewolf.com/Printe...artId=LABOR-BP)
I've already mucked up once messing with the breach plug fit, and have galled 1/2 of one thread on the plug and took a small bit off the thread inside the bore. I didn't properly see to it to avoid seizing. I don't have any issues placing/removing the plug since I've been using proper anti-seize.
To my questions.
1. Is the amount of attention outlined on the ToW website required? I don't want to cut corners and end up blowing my face off if I do this wrong.
2. How much force should I need to apply to the plug in order to ensure proper fit? Moderate force lines it up with the top flat on the barrel, extra force the next, and extreme force mostly lines up with the side flat. This, of course, without having modified the barrel or the plug.
3. The book mentions a potential need to test fire the gun post-build from a distance. Is that necessary when using a modern barrel?
I'm quite green on this build, as the oldest firearms I've built or restored are from WWI. Any wisdom will be greatly appreciated. Thank you.
