I bought a 4D8 from Calvin, but one of the axis won't turn. It's probably just jammed because it's never been played with, if anyone knows how to pull it apart without breaking it so that I can check it and get it working that would be appreciated. It is supposed to turn on all 3 axis isn't it?

Cheers,
Burgo.

Doesn't the 4D8 work like a 2x2x2 and can therefore disassembled like one? Like one from Rubik?

Hi Andreas,

Thanks for the response, yes it is supposed to function like a 2x2, but I can't turn one axis. I just wanted to know how to disassemble it before I attempt it, and possibly break it. It doesn't have any give, so it mustn't be sprung, which makes disassembly precarious I think. I haven't pulled my Rubiks 2x2 apart, because it's old and I don't want to damage it either. Someone must know how to disassemble it (or if the mechanism is prone to lockups- or if it would be glued wrong). Or have some general experience with it.

Calvin has great customer service, but I don't want to trouble him yet if I can fix it easily (I was surprised he had a few because Mefferts has run out).

Cheers,
Burgo.

OK everybody, you can all stop looking now :).

I found the problem, I presume they use the same mechanism for the Pyrastar and Pyramorphinx, but different caps are glued on. The glue had gotten in between 2 of the 2x2 internal surfaces. I found where it was and picked away at it with a scalpel until I separated the pieces and now it functions well.

Cheers,
Burgo.

It is good to know that you have solved the glue problem.
Usually, I shall simply replace you a new one if it is defective.
Thanks for your kindness and support. ^^
Enjoy !
