The screws that hold the layers together are torqued down pretty tight. I usually have to use a punch and hammer to loosen them before they’ll unscrew. Also, they used some sort of putty to help blend the edges before painting, so anyone who plans to delaminate a door should be ready to re-putty and paint the edges.
The gear train on the safe I posted was held in place with poured lead. Guess they did that to keep the slop to a minimum. Makes it kind of difficult to remove, though.
Oh, and fun fact: apparently one of the techniques used by early safecrackers involved delaminating the door. They’d beat the front of the safe with a hammer to expose the ends of the screws (like the ones that are visible to the left of your dial, Mordy 🙁happy): ), then drill them out. They’d continue this process layer after layer until there wasn’t anything left of the door!
