Any ideas how to make this dial usable?

Emery sticks sounds like a plan. It might even be time to get Dremel and some polishing wheels. 

That sounds interesting. Is there a particular setup you use to do this? Is it just reversing the polarity (nickel plated item on the negative terminal) and a copper (or similar) electrode on the positive, all in a non-corrosive solution

I love that idea. I don’t really drink either (and the kids don’t own a bar) but I am prepared to take one for the team to get a few corks! 

Pop into your nearest yuppy bar and ask for a handful. Chucking the case onto a cork gives you full access to all of it. You don't need a vice as it's so easy to hold the cork between your fingers. One of my friends was throwing away some kids playmats that were never used. They were made of a medium density foam and the pieces squeeze up enough to push a domed crystal onto and hold it in place. Again the addition of the cork means you can pick it up and work at eye level with it, if you need to inspect it at different angles under better lighting.
