Hello Folks,
I've seen several methods of building stubbed barrels, so I'm wondering what is the best. I've heard of boring out the stub and turning the breech end of the barrel to a 2-3 thousandths interference fit, then freeze the barrel and heat the stub and put them together, sort of like putting bearings on an axel shaft. I've also heard of threading the barrel and stub and screwing them together. There may be other methods.
I've also heard that it is very easy to misalign the parts and end up with junk. I'm not sure if this happens during the lathe operations or the assembly of the two components.
Anyway, if you know anything about this process, and care to weigh in, please do.
I'm aware that at least one member here makes his living doing these jobs. I am NOT ASKING for him to give away his shop secrets. I do not want to take business away from anybody. I'm only asking for common knowledge among amateurs.
Thanks, Tom
