Stiff 4x4

Hello everybody,

One of my 4x4's it quite stiff.. The outer layers are quite allright, but when I try to move two layers, it feels as if the core is pretty stiff... Does anyone know a way to modify the cube, or to make it less stiff?

Thanks!

Jo?l.

Have you tried opening it up and looking for imperfections to sand down?

If the imperfections are on the outside or just inside the groves that run around the core, you should be able to take care of them. If the imperfections are too far inside the grooves, you may want to exchange it for another one.

Hi Joel,

The core of the 4x4 has screws on each of the eight triagular pieces (spherical geometry). These pieces are glued in, but I believe if take the screw off you can break the glue and loosen the piece. I haven't done this on any of my speecubes, but I did remove one of these pieces on a broken 4x4. If I get some time I'll try this and let you know how it works.

I've done it, it doesn't help that much. It causes it to jam more often, but rotate easier... So i dunno, they kinda even each other out.

Have you tried drip silicone?

I dont know too much about lubing, but the spray I have has a small tube that is attachable and you can get into the center of the cube rather easily.

Haha, guess i'll throw my two cents in as well. I would think that grinding the sand down in there and then cleaning it out and lubing it with some silicon spray would work...but i'll also throw some of your own advise back at you. You said that lubing a stiff cube sometimes just makes it worse...You also said that one of the best ways may be the most natural, just using it a ton. Well...good luck with that.

I assume this is because the pieces can wiggle around once they are loosened. But what if you put a layer of hot glue (or some other filler) to fill the gap between the core and the piece? I'm still only guessing here though. Any thoughts?
