When a safe tech wants to drill an antique safe, if the safe is to be repaired, You really want to preserve the dial and ring if at all possible. I have seen the tools they use for pulling the press on dials with minimal damage. What do you do when the dial is not just pressed on. Maybe the spindle is cast in, or attached from the rear in an inaccessible or unidentifiable way. On a fire type safe it's feasible to drill an angled hole, but on a real safe that can be pretty tough. Generally speaking what options are there aside from destroying the dial in removal?

I always feel like an ass when I destroy something only to learn in the process of destruction that there was a better way.
