2X12 is great, 3/4" plywood would be easier to handle and to drill through when you need to. Chalk your plate line where the wall will go on the room side, rip your plywood to go to the basement wall and 1/4" shy of the chalk line. That way when you set your upper plate you can still see the line to accurately set your wall. To answer your question, using ...

Screws can't be pushed back out. They'd have to be twisted out, and the lengthwise force on the flat helical edge of the thread from tightening the screw down will remain ...

Nailguns are generally used on plywood by people who need to set thousands of nails. When you are doing a small project, a hammer is a better idea. On good quality stairs, oak is used for the treads, one of the reasons being that it does not split readily. Also, good quality treads are tennoned into the risers, front and back, which binds them and prevents ...
