Lynn, you've jogged my memory .... I started with the coarse valve grinding paste, graduated to the very fine VG paste and finished with Al-oxide powder compliments of the Earth Sciences Department at Monash University - the stuff we used to use for the final grinding of rock specimens mounted on glass slides.
Sorry Harry to have neglected to give you the full picture - it was 40 years ago! I'm sure jewellers rouge will work just as well as Al-oxide (if it's not the same thing with a fancier name) I think I also replaced the little tensioning spring at the bottom with a new one.
Mike
