Time to drill some holes for the Gauges. I decided to make 70mm holes in diameter using a hole saw. It´s quite a cheap tool (about 12€) which you can attach to your drill. panel.
The edges will be quite rough so I used the router with a 45° bit to clean the edges and add some detail to the panel (or use sandpaper and your hand:))
For the annunciator panel I only used the router with a follow/contour bit. This gives you a perfect result but needs some more preparation. Therefore you create a guide in advance which you have to attach precisely to where you want to make your cut. The contour bit will follow the edge of your guide and leave a perfect cut including nice rounded egdes. Any mistakes on the guide will show up here as well so invest some time in your guide and it´ll pay off nicely.
