Sounds a bit drastic. Italian thread is wider than British so it would be quite a task needing Milling out, sleeving and re -tapping to British thread. Wouldn't it be easier and cheaper to use Italian BB?
I'm hoping 1mm each side can be removed with a Facing Tool and the threads don't need to be touched, I'm gonna try put in an Italian threaded BB like you suggested as soon as it arrives, hopefully that works , the BB shell is 70 wide with English thread at present, cheers
