Getting access to an industrial lathe to turn the muzzle end of the barrel down. It has a pass through that will allow me to bring the barrel through the center of the lathe.  Hoping that the lathe dimensions will let me leave the receiver on the barrel for the milling. However if it doesn't I will need to remove the barrel. Can one of you point me to a forum thread or anther source for removing and replacing Krag barrels and head spacing considerations?

Thanks,
Mark
