This is an abrasive disk, rotating at 1500 rpm. When I shine my flashlight at it, it carries the glow with it, approximately halfway around the disk. What am I seeing happen here?

It sounds like you got the answer to your question, so I need to ask, what the heck weird kind of flashlight is that?
It’s a cheap LED pen light, they hand them out like candy where I work. Most of us have our own flashlights anymore.
