Thanks.
The only solution is a lot more light, far beyond the ability of any on-camera flash. But I was able to figure the photos out anyway.
As I thought, the shield covers only the chuck body, and seems a bit too short (along the bedway) to catch coolant flung from the jaws. They do make a larger/longer model, if I recall.
How well does it catch coolant? If I recall, you are using a soluble oil of some kind.
