Yeah, I measure the length of the screw, divide by the thread pitch, count turns per inch, factor in the inch-pounds of torque required, always start the screw slots in an east-west orientation...... The cock screw alignment is a real problem, you have to grind down your flints to +/-0.0025" once you determine the required thickness for your lock!
WHAT A HOOT!!!! No engineering involved at all! Just stop turning them when the slots are in line, or back them off till they do. And it's just for the cameras anyway, because there is always someone out there who has to mention it if you don't!
I don't think I ever even thought about the cock screw slot alignment....it just happened
