Measure the depth of your knee wall. Cut a piece of 1x8 pine to this length plus 4 1/2 inches. For example, if your knee wall measures 11 1/2 inches, make your cut at 16 inches. This piece will serve as a base for the column.
Using a router with an ogee bit, router the edges of the base piece. Leave one of the short edges un-routered.
Measure the width of the knee wall. Using a jigsaw, cut a rectangular piece out of the base. The rectangle should be 2 1/4 inches deep and as long as the width of the knee wall.
Put the pillar base on the knee wall and make sure it's level (Image 1). Use shims to correct the level, if necessary. Remove the base and apply construction adhesive to the knee wall. Re-insert the base and re-shim, if necessary. Nail the base into place using the nail gun (Image 2).
