Sometimes not knowing makes them stronger.I think it's amazing that the stairs didn't collapse. Most of those stairway stringers end up being a 2x4 by the time the steps are cut into them. I've even seen pre-cut stringers made from 2x4s with step risers tacked to them. Two 2x4s don't carry a lot of weight.
I MUCH prefer @Dabbler s approach to custom carriers that spread the weight out.
Still a risky operation no matter what you do.
