The method I have used aftert experimenting with many of the methods in shop man using torque wrenches---dial indicators etc. it comes out the same as the "fancy" methods---
If the castle nut moves easy on the threads with fingers ---tighten with wrench,or pliers while spinning drum(seats bearing), back off nut till "loose", tighten as tight as you can get it with 2 fingers while spinning drum, back off to first alignment of cotter pin hole

Never give in to the urge to "just a little tighter, the pin holes almost line up"
