Microscope Reflector

A few months ago I bought a couple of old microscopes from a junk shop. They were pretty cheap, but the carriages were seized. I managed to free them up and they work nicely, but on one of them the mirror used to reflect light onto the sample was missing. It was a simple disc shaped mount, so I turned one up on the lathe:

The metal is shiny enough for this to be good enough to use without a mirror. i may cut a piece of mirror to fit, or, more likely, I will add some form of LED illumination. Messing about with a mirror is a bit of a pain anyway.
