Today I have cut out the eyes. First I taped a template to the smooth (back) side of the reflector and traced the outline with my cutter and a metal ruler.
I removed the mask and protected the inside with removable tape to protect it from being damaged by accident.
Then the cutting began. It is said that cutting at high speed would be dangerous because the material would melt and damage the part and the machine. So I started at minimum speed and took a short break every minute to allow the part to cool off. This procedure was a bit too slow for my taste and I increased the speed of the machine to medium.
Everything worked as planned. Nothing melted. When I was cutting out the second eye I became tougher and switched to high speed! It worked but I was attacked by flying bits and pieces of hot reflector material. The parts got really HOT and felt like needle stitches where they hit my skin.

However, that way I was able to cut out the part much faster. Man and machine remained unharmed during the process (I was wearing my goggles

).
When I separated the rotating blade from the machine I noticed something weird: Some of the reflector material had turned into some sort of "candy floss"!
However, disassembly and cleaning was very easy.
The rim was sanded smooth and the eye parts were ready for further assembly.
A quick foil test to check the colour:
Yummy!
