Wood – Stair skirt board protruding from wall by ~1/4″ – can I use a belt sander to sand it down

sandingstairswood

I'm doing my own stairs remod – long story short, I'm regretting it. It looked deceptively easy, but I've regretted it and I have a bunch of little errors that are adding up.

One such mistake is that the skirt board is in, can't be removed and it protrudes from the wall by a little less than 1/4 of an inch.

How would someone who knows what they're doing try to get rid of this protrusion so it's flush with the wall it's against? I'm afraid sawing will be sloppy (especially if I do it). Would a belt sander work?

This isn't too tough. Make your life easier by finding a plinth block that coordinates with your rail system or other nearby trim components:

Use whatever tools you have on hand to trim the skirt back about 3/4" from the wall corner. Fit the plinth block over the end of the skirt to act as a cap. This way you don't need a perfect cut on the skirt, and you don't need a miter return into the wall.

A technique I've used for this is to rabbet the back corner of the plinth block using a table saw. Run from the bottom upward, and stop short of the top of the block. This leaves a curved notch that can fit the top profile of the skirt rather nicely.
