how to scribe stair skirt
Re: Skirt Board On Existing Stairs. Or....just lay a 1 X 12 on edge running up the stairs, resting on the tips of the treads. Scribe down to the treads the right amount to make it line up with your 4-1/4 base. Use a framing square to mark for riser cuts. Then if the risers are angled back as they sometimes are in a carpeted situation, scribe the skirt board back after it has been scribed down. This will usually require that 2 boards be connected together to cover the entire length of the stairs.
