I drew the design I wanted and cut it out using a jig saw, the inlays are from a router cut, after sanding the strip inlays flat I repeated the process with the 4 dots at their bottoms.
The process for making the various holes on the project is as follows, I wanted an exact fit for the fuse box, and the radio brass inlay.
I used a top follower bit and made a jig from scrap wood.
the fuse box width was copied by placing it between the blade and the fence, this made the wood I cut match it's width perfectly, I suppose a good craftsman would just measure, the third pic is setting the length, I just pin nailed the edges to the middle pieces.
Now place that over the hole you have roughly cut and clean it up with your top follower bit and router.
