It’s the only way to be sure.
It was heavy but once it got moving, the wheels loosened up a little and it wasn’t too hard to roll into a more convenient location for further activities.
It is now appropriately positioned in my lair for a safecracking robot, safecracker, or adornment with potted plants.
Very exciting! Can you tell us what you know so far? Do you know if it’s a 3-number or 4-number combination? Which way to turn it? How does the dial feel? Does it make little clicking sounds as you turn, in either direction? Does applying pressure to the lever have any effect on the feel of the dial? (It may just be a handle, because I think some of these locks are opened by the force of some final bit of rotation after the combination has been fully entered.)
Hmm. Is there enough of an edge there to just jack the front and back apart, assuming more gentle methods don’t succeed?
No skeletal remains where a boy wizard was walled inside several books ago?
Wooot!!
Don’t be so disappointed, it means he escaped! Either that or he’s in the safe.
Could you hear the doubloons splashing around?
If you pick it up and shake it, does it rattle?
Don’t give me excuses, it’s a simple question.
Arrrrr. There be treasure in that thar locker if you be hearin’ it rattlin’.
Maybe he’s in the upside down?
Those hinges aren’t very convincing.
That gave me a good laugh.
I feel rather ambivalent over all of these recent developments. The end of this thread might be nigh!
Though at this pace it might take a few more months…
My bet is the lock mechanism extends into the frame on all 4 sides. This would prevent the door from opening, even with the hinges removed.

If you pick it up and shake it, does it rattle?
yeah, are we getting LEGOs for christmas?
