I put the technical data at the end of this email. I'll give you the Blah, Blah, Blah first.
I tore out the old interior staircase from the
1st to 2nd floor in my house. The old staircase had 2 stringers.I cut 3 stringers and when I put the middle stringer in it severly limits the head clearance when I go down the basement. Because of this, I would like to omit the middle stringer.
I'm about to screw and glue and I've asked everyone I know what to do and I get conflicting opinions. If some of my advisors wouldn't throw in comments about the decreased weight capacity of the staircase, that 3rd stringer would already be in the coal stove.
Location: Interior 1st to 2nd floor Stringer Length: 14 feet Stringer Lumber: 2x12 pine Tread Thickness: 1 inch Tread width: 31 inch Tread Depth: 10 inch Building Inspection: No
Is this a bad idea? Is 2 stingers enough for a stairway 31 inches wide?
