John, I would be setting the backlash at least somewhere close before doing the blueing, as it will influence where the teeth contact to some extent. It's important though to realise that with worn gears you will struggle to get perfect adjustment i.e. you might well set 4 thou backlash and find it has all gone tight and feels rough when turned over. In such a case extra backlash is infinitely preferable to 'tight' gears.
