A customer of mine asked if I would take some photos of how I installed his bolt knob. Since I was this far I figured I'd share with everyone my set up for installing bolt knobs on Remington bolt handles.
This is the fixture I built to hold and align the bolt handle. I then turn the knob down to size.
Then I set up and single point thread.
And this is the custom knob I built for him. A little longer than normal but it's what he wanted.
