One turn after hand tight is WAY too tight.
If the bearings and spindle are ok as tight as you can hand tighten while spinning the drum clockwise, then the closest cotter pin slot.
People's way of doing it varies, but the basics are the same.
Of course if you get it hand tight and have any wobble or play in and out or up and down there is a problem with the nut bottoming out before the bearings are tight in the races or a worn race seat in the hub or on the spindle.
I have seen where an old bearing seized and spun wallowing out the hub or eating the spindle, but it's pretty obvious when you see it.
Seriously, they only need inch pounds, not foot pounds.
