I needed to cut some splines for a Walnut door for a rifle display case I'm building and thought I'd do it on the CNC.

 

Here's the door with splines before gluing and sanding -

 

And here's the video on making this -

 

Enjoy!

If the blank for the splines is a little thick you can raster the thickness before you cut them out and save time sanding later.

One other thing David didn't mention the grain in the spline should be running the length of the spline and not across.. David did cut the splines correctly, I just wanted to let others know because I have had people want to know why their joint failed when they added a spline to strengthen the joint, their spline had the grain running across instead of along the length.

As St.Roy says, "Planes of strength and planes of weakness."
