Defective Dayan ZhanChi 3x3x3 cube

**CarlBrannen** · 07-02-2012

So I was happy to see a black Dayan ZhanChi arrive in the mail today from speedsolving.com I tore the package open. The white face was very difficult to turn. Difficult as in requiring strength. WTF?

I took it apart and found the problem. One of the screws was out of spec, it's head was too wide and was snug against the plastic center cubie. This might have been noticed at the factory because it was sufficiently hard to turn the screw that I slightly damaged it as you can see in this photo (defective screw on the left). On the other hand, I suppose they use power equipment to screw these things together:

That was easy to fix. I had a couple packages of spare Dayan screws and swapped it out. (Interestingly, the Dayan ZhanChi uses a different spring from the GuHong. I'm tempted to measure these and see exactly what the difference is.)

Now that I had it apart, I discovered another defect. Two of the edge cubies were missing their torpedoes:

WTF?

Anyone else get these kinds of problems?

I actually just had this. The yellow side of my ZhanChi is messed up, and am getting replacement parts from theCubicle with the rest of the order. One edge was missing a torpedo, and the screw went up against the center (although I think it's the center, not the screw)

I think I got 2 extra torpedoes in a diy zhanchi I just got. Does that mean someone else is not going to get those 2?

Of course not they're just spares.

I haven't had this problem before, but lubricating the screw and the plastic it's rubbing against might help.

Contact the seller, I'd say, I am sure they will be of perfect assistance!

Sounds like your lubing method.

**CarlBrannen** · 07-03-2012

I think that if your screw rubs against your plastic (which was the problem I had), you need to replace (or modify) your screw if it's bent or too big, or maybe your spider. It shouldn't do that. No amount of lube is enough to fix broken geometry.
