Now you've seen one. :)
For those who did not know TW here is a sample of his work. He made ordinary locks into work's of art.
The malfunction your experiencing is from a worn fence. The top part is worn allowing the nose to ride out of the wheels gates before it clears the stop.
I'm confused as to the hand of your door. This would make a big difference in the dialing sequence of your safe if you have a left hand lock. Posting a picture of the full front would help.
Chip, I've never seen the inside of a 10. Thanks for posting that one.
As to the locks having issues with bolt pressure.
One of the first things, we safecrackers do, when we begin the diagnosis of a locked safe, is to check the movement of the safe handle and play in...
another name for that is Snake Eyed security screws/bolts
The ends appear to be the same style as pig nose security bolts. These tamper resistant bolts have two indentations that require a special wrench; they are also known as 'two hole' bolts.
