coincidence
my OCD can confirm this coincidence, since it doesn't happen to me.
Quoting: Mordier L'eft you count stairs too and find they are not built in sets of 13? I dont believe you. the below poster proves they are in sets of 13. Wall height is 8 feet.
When cutting the stringers for a staircase, there are codes that must be followed.
Here, it is a rise of no more than 7.75 per step.
The variable between the rise of the first step and the last can be no more than 3/8 inch.
Usually the general rule is 7.5 rise by 10 inch run.
Depends on the floor finish.
Do the math.
Quoting: Waterbug Damn beat me to it...Nothing to see here move along There is the esoteric and the exoteric and the freemasons are the master builders who use stairways as an important part of their traditions and rituals. rather than saying there was a conspiracy I was merely highlighting the link. I have no issue with the number 13 either. so why is the wall 8ft and the rise no more than 7.75? why not 8.5ft and 7.5 rise?
