Are you between sizes?
Sizing is not super-precise. Personally, I can use either a medium or
a large about equally well. It's more of an issue if you have large
knuckles, just as ring sizing is with some people. Pick the larger of
the sizes you're between, and it works quite well to pad the inside
of the Delrin ring with something. Tape isn't bad; a cut section of
a bandage is ideal. You'll have to experiment a little to get just the
right amount of padding. Brooks Story, the man who invented the Axys,
sets his up this way.
Does the metal part of your Axys not look bright and shiny any more? Brass darkens with time, eventually becoming almost chocolate brown. Many people — especially those who love brass — prefer this color. But if you would like your Axys to be bright and shiny again, it is safe to use just about any commercial metal polish. With just a little rubbing your Axys will shine again.
