If so, how far did you/would you dare to go?

Not for nothin', but you still wouldn't get enough bore to be worth the
trouble. The current species of large-bore machines have MUCH larger
bearings and journals. Why ruin an otherwise useful machine?

If you really need a bigger bore, pretty it up and sell it (Atlas lathes
don't claim a high price), and buy a big-throated beast.
