Building the Plinth Base

The supporting pedestal-like portion of the room partition is known as the plinth base. The new one is built using the material and specifications to match the those of the existing original one. It will serve to support the square column that will extend up to the ceiling and be capped with a decorative crown.

• Begin by comparing the measurements of the existing "ghosting" on the floor--i.e., the remnants of where the old bases were previously removed (figures A and B) and the existing plinth bases (figure C) to determine the proper measurements for your new bases.

• Using the 1/2" fir plywood, cut out the front piece and side panels for the base, following the dimensions of the existing base (figure D). Sand surfaces smooth.

• Determine the size of the trim needed to wrap the exterior of the plinth base. Mill the trim by ripping the 1x6 fir stock to width required (figure E).

  Note: When replicating historic elements, you may need to custom cut your wood since the historic sizes were typically larger than the standard sizes used today.

• The base is held together using 2x4 braces secured with screws inserted into recessed holes created using a pocket-hole jig. Use 2x4's to create an interior frame, cutting the stock to the interior dimensions. With the basic elements of the base cut to size, assemble the base using the pocket hole jig and screws. (figures F and G).

• Apply the trim panels to the base nailing using 2" finish nails, butting the joints together (figure H) rather than using mitered joints.

• Once assembled, test-fit the plinth base to the edge of the wall and stairs. A cut-out will need to be created in the base to accommodate the bottom stair.
