Highlights:

Step 1: Create a Plinth Block

Begin by ripping the 6/4 (net 1-1/2") x6" poplar stock to width.

Plane the material to a thickness of 1-3/8" (1/8" off of the 6/4 material).

Cut the material to height to match the existing 12".

Set up the profile bit into the router and run the top edge through to form the profile.

Set up the dado cutter head in the table saw to a -1/2" width and run additional detail through top edge.

Sand and pre-prime for installation.

Step 2: Create Corner Blocks

Cut the of 4/4 (net 1") x6" poplar stock to a width and height of 5-1/2".

Center the piece and end turn cut on lathe until profile is achieved.

Sand and pre prime for installation.

Step 3: Create the Trim Base

Begin by ripping the 5/4 (net 1") x4" poplar stock to trim profile width (2-1/2").

Set the knives in the cutter head and begin to run the profile through the molder multiple passes until profile is achieved.

Rip the additional 4/4 material to 9-1/4" width and length as required.

Chamfer the top edge as required to match the existing edge.

Setup dado set on the table saw to run a -1/4" dado along the top edge of the base between the chamfer and the back of the base.

Place the profiled trim piece into the top edge of the base material. Sand and pre-prime for installation.

Step 4: Install the Trim

Begin with the installation of the plinth blocks at the lower right and left corners of the door using the pneumatic finish nailer using 2-1/2" finish nails.

Next, measure and cut the door trim to the height of the top of the door jamb. Install the left and right vertical trim boards using the pneumatic finish nailer.

Nail the outside edges using the 2-1/2" finish nails. Use 1-1/2" finish nails on the inside edges.

Next, install the upper right and left corner blocks using the pneumatic nailer with the 2-1/2" finish nails.

Measure and cut the remaining piece of horizontal trim between the two corner blocks. Secure the trim.

Measure and cut the base material to fit as required. Mark the locations of studs located behind the plaster on the wall. Support above the floor using spacers approximately -1/4". Nail to the wall using the pneumatic finish nailer.

Finish by filling nail holes using wood filler, and finish paint all using an oil-based paint.
