As part of the basement fixup, I am replacing the stairs. Currently, 2x
stock nailed to three stringers. The walls are on both sides of the
staircase. I am going to replace the 2x treads with oak treads. To
maintain the current riser height, I am putting down 3/4 plywood.
Before I install the oak treads, do I put the riser on first butting to the
plywood, then the oak tread -or- does the tread go down first, then the
riser goes on top of the tread?
Thank you for your time.
