i am glad to read some of the replies on this thread in regards to safety. these replies reinforce a point i had tried to make elsewheres on the safety of using some techniques and materials when making or modifying a barrel. terribly theres a group who seem to feel theres no inherent danger in these kinds of methods, and even defend the practice of them, and will stand behind those who do them. i dont think anyone here was being too out of line in thier replies, they just said what the had to with the safety of you and others in mind. there is a wealth of reliable, trustable gun building knowledge to be had here from these guys. safety is no area to cut corners with, no matter what the project is. a new barrel is much cheaper and easier to live with than a terrible accident.
