When I restore, I like to freshen up the badge by rubbing it with a typical pencil eraser- a sort of mild abrasive- and finish with a light spray coat of lacquer, it really brightens it up.

Thanks for the tip. I'll give that a shot.

That's not an old grinder. This is an OLD grinder! I pulled the original flat belt sheave off the shaft and replaced it with a modern V belt pulley. But that arbor is at least 150 years old now, if it is a day. Now that's an old grinder. Oh, and I made that whole frame it is on now too. It was probably mounted on a rough hewn beam earlier in its life. Lacking the space for such an installation I had to upgrade things slightly. I used to run that on a big wooden base though. But even that took up too much room in my shop.
