Hello!
I've been wounding for quite some time how screw head alignment was done in the past.
As far as i know in present time cnc machines has a spindle position sensor so that all screws threads and slot can get cut precisely the same way.
here is a old sbs shotgun action from around the 50's, how wore they able to machine the screws and tap the holes so they lined up ?
