Ive read the various forums and people have mentioned about squeezing the layers together. There is no squeeze at all between my layers. I don't want to be someone who cries that their puzzle is "broken" as having solved most others, they are quite simple mechanisms. The only magic is up the sleeve.
However, with the layer being quite stiff, in fact I am starting to see scratches around the locus of movement. Makes slight grinding noises while turning them now??? Most saying the placenta locks at the rear facing away from the key chamber. Few saying theirs was NOT facing away when it locked. Is mine the only one that gets jammed at 45degrees?
Disappointed with this puzzle as I don't believe they should be painful to manipulate. It's not as if they are ancient Chinese finger traps (even if it feels the same)!
Unless I make some headway soon, I may have to give in and use an X-ray to get an internal image
