This is an example of how to build a compass style deck inlay. I will provide all the measurements and illustrations to assist your understanding. The raw material will be pressure treated deck boards, 5/4, at a standard 5.25 inches wide.
To build this design, there is 4 different pieces you will have to build. (To get the mirror image you just turn the template or material over.)
A – Qty 8
B – Qty 4
C – Qty 4
D – Qty 4
Below you will find the measurements and angles of the 4 different sections that will make up the inlay.
As you have probably already noticed, section “C” and “D” are missing the center lines. This is achieved by creating a false seam.
Draw a line down the center of the section. Using a circular saw cut along the line 0.25 inches deep. This line adds visual complexity to the inlay and is also very handy when painting (if you decide to do so).
Assemble the inlay on a flat service so you can adjust and fine tune you cuts.
Pre-drill the screw hole using a 3/16 inch drill bit.
I think the best way to get the inlay ready for installation is to glue it together using construction glue such as PL Premium.
Note: The inlay is much easier to stain or paint before you glue anything.
Using small amounts of glue, glue the edges of the boards together. You can hold all the pieces in place using a few screws in the pre-drilled holes.
This step is to make the installation easier.
Let it set overnight.
