Straightening rifle barrel

[tangolima]

That's exactly what the book said. I saw such a straightener at the Springfield armory museum.

I may try the poor man's method when I run out of things to do. The book describes how to detect which way the barrel bends, but it doesn't tell how to determine the exact location of the "elbow". Guess it would a matter of experience and trial and error. That may be why the operator needs to keep looking down the barrel while working the wheel.

Also notice the angle? There is a bright light out there.

I believe some used some kind of light system that reflected how bent it was.

They do. It's called daylight. You look at a window up high enough on the factory wall that traffic crossing the factory floor doesn't interfere with your view.
