This circular fluorescent light, made for a microscope, fits around the spindle on a mini mill.
It provides good, even light on your work.
The hole in the light is 1.85" in diameter. It fits the mini mill fine, but if you have a different mill you had better check to be sure it will fit.
Chris' Tips I installed the light with a strip of velcro. I can quickly remove it if it gets in the way. I used the three mounting screws to center the light on the spindle before I stuck the Velcro in place. (Remember to remove or back the screws off before you turn on your mill.)
I think I will add a small bracket at the front. The bracket will have three holes, two where the chip shield mounts and one for the threaded hole in the light.
Here is a photo of the light installed on my mini mill.
