No, not tried it as such but have used an MT2 to MT1 adaptor for a pen drive mandrill, it was OK. if your work piece is small then would a ring drive work for you?
Just looked at the Chronos site, that crown drive appears to be attached to the MT shaft with a grub screw, it may be worth contacting them to see if there is an option to buy an MT2 shaft with the same head fitting.
