I'm using what seems to be the generally accepted formula i.e. for the outer bezel diameter of the stone + thickness of metal x 3.14 and for the inner bezel diameter of stone minus thickness of metal x 3.14 but it's just not working out for me. The outer one always turns out too small so I usually end up using that as the inner step but thats not ideal as the solder join is then between the inner and outer so lots of faffing to get them to fit and also the height would be wrong for the inner so that has to be adjusted. Then the stone is supposed to 'fit snuggly' but it never does so lots of filing to get it to fit and then by the time all the soldering has been done the metal has shrunk and the stone wont go in again!! Or by the time I've got the two bezels fitted together they're too big for the stone!
Has anybody got any advise? Is it just practice? It's driving me mad.
Thanks
