Viewing heat on your lathe

With a thermal camera you can have a whole new perspective of the world around you. In the picture below you can literally see hot chips flying off the workpiece on my (not yet finished :smash:) DIY mini lathe. This is the main way heat leave the workpiece, and it is clearly visible from those bright sparks.

I have visualized heat of the spindle from ball bearing friction, the belt and motors. And of course I also investigated further, ending up to discover a serious potential fault in the photovoltaic breaker (that if not detected could lead to a fire!) in my house.

You can see all that and understand how this whole thing works, and how to correctly use a thermal camera (yeah, there could be some tricks) in my latest video: https://youtu.be/CauoZbcuifY

That is something I never thought about. That is very interesting.
