There is a pin inside to lock it. It is not just to push them apart although you know part of the secret

Below are comments that were archived on Haloscan.com

===========================

The assumption that one would probably make is that the wedges sides continue as is into the centre of the block and to the other side of the block (cross formation). Which it obviously doesn't. If you design the wedges track its edges from one wedge to the other wedge around the next corner, thus allowing to shift in the the blocks upon each other. thus the two wedges would run parallel to each other.

==================================================

Yeah, what the above said. I included a link to my blueprint (a messy version, anyway).

Assumptions be damned!

==================================================

Daria's comment and blueprint is perfectly right.

This one seemed obvious to me, though I have to admit that I am used to create wooden objects...

This one is definitely the next object I'll create! (will even be a box)

==================================================

Andre, Excellent work.

Here is Daria's blueprint.

it slids on the diagonal, isn't it?

Ha. I came up with a completely different method of doing it when I saw the item at puzzlephotos and didn't give it any more thought.

In my mind, I saw the dovetail notch as an arc, a quarter of a circle, that would allow the pieces to separate by turning one.

Elijah | 05.24.05 - 4:16 pm | #

==================================================

If you were able to turn one piece then they wouldn't be two solid pieces with no gaps or holes inside. But if that wasn't stated on photo puzzles then you have a workable idea.

==================================================

to me it looks like they probably just cut a square block around one end to make it look like it was actually carved in dovetails. also, for the top pic, some creative and careful painting was used. the fact that when you pick up the top the bottom comes with it and there's no obvious way to separate the 2 only serves to make you think "inside the box" when its always better to think "out of the box!!" i love this site-it really makes you think out of the box. it messes with your perceptions of life and reality-its so cool!! i don't know if i'm right about the box-i hope i am-if not someone pls let me know!

==================================================

Chanda,

There were more posts here previously explaining this puzzle. Now the puzzle is for me to figure out what happened to them. (turns out that with Haloscan comments are archived after 4 months)

Check out this image.

The dovetails are not at a 90 degree angle to the side of the cube, but rather a 45 degree angle providing two "rails" on which to slide the upper half onto the lower half.

Nice one.
The "joints" that keep together the two parts are actualy paralel to each other, (they are not going from a side to it's oposite and crossing each-other in the middle, but rather from the middle of one side to the the middle of the oter perpendicular to it)
