An update. After making many parts, I have decided the coolant mister is fine as is. The coolant oil mix is thicker than the water, this makes it work better.
Here is a short video of it in action. It is adjusted to be mostly air, so hard to see the spray in the video. And the gyro mounts it was cutting in the video.
I remade one of the mounts due to the hole in it. I didn't change the tool offset when I changed mills. Added a picture of the Gyro mounts test fitted on the Bergen camera mount. Now off to polish, and anodise.
