This is the second occasion in which I've entrusted my rifle to a supposed competent gunsmith, paid my hard earned money and been let down. A threading job that's a right bloody mess and on a fluted barrel to so can't just be chopped and started again. I'll sort it with him but I swear that this is the last time I'll do this.
About a century ago I gained a degree in aero engineering and even longer than that spent some time on a lathe. I'm in no way an experienced metalworker nor even consider myself knowledgeable but with a bit of revision and training must be able to perform the basics like re-barreling and threading for myself.
So can anyone recommend some books, videos or courses from which I can learn? Consider me a complete beginner as I intend to restart at the basics. i
Any advice and guidance gratefully received.
