How to Make Victorian Plinth Blocks

Materials

Step 1: Rip/Bevel the Flat-Stock

Rip the MDF board down to the widths you’ll need to make all the pieces of the plinth block.  This plinth block I made 4″ wide, the same width as the pilaster.  I put the 45 degree bevels on the edges with my table saw.

Step 2:  Cut to Size

I cut the pieces to size (7″ tall and 4-1/4″ wide) on my miter saw, and them assemble the pieces on a flat surface.  I usually do this work on top of my miter saw where I can square everything up against the fence.

Assemble the parts on a very flat surface.

Step 3: Assemble

I’ve assembled all the pieces nice and square, spackled and sanded the plinth.

Step 4: Install

Use lots of Liquid Nails on the contact surfaces between the plinth and the wall.  I shot 2″ long brad nails to hold it fast.

Step 5: Install the Pilaster

Install the pilaster on top of the plinth and then finish the rest of the door surround.  Note: Don’t install the necking until after the baseboard in installed.

Step 7: Make the Necking

Make the necking as one piece and then install it on top of the plinth block.  Note where the necking meets the baseboard — I rounded the end of the necking molding so that it fit snugly into the cove of the baseboard.

Step 8:  Install the Necking

Install the necking on the plinth block.  Glue and nail it in place.
