There are two ways to rebarrel a Vanguard. One is to lock in the lead screw on the thread pitch
and never unlock it until completed. (You must turn the lathe by hand)
The other method is to find a thread pitch that is very close to the metric threads pitch,
set up in the middle of the metric thread in the receiver( This cuts the error in half)
You want to reduce the error by only .004 or .005 thousandths and by setting up in the middle of
the action threads you are only cutting one side of the threads going in and the other side going out.
This way you will end up with a standard thread pitch without removing to much of the receiver threads.
The barrel can then be threaded to fit the receiver threads.
This is very tricky but it saves cutting to much out of the receiver ring by removing all of the metric
threads and re-threading to a standard thread.
Shortgrass can cut you a metric thread (He has a setup for this) you can PM him or maybe he will
