Qiyi Square-1 Core Stripped

[guysensei1]

How it happens and how it can be fixed is still a mystery. What it looks like is the cube loosens itself, getting more rapid as the problem gets worse. Mine got to the point where I couldn't scramble it without it becoming unusable. I have it glued in until I can get a replacement part. I've done 2000 solves on it.

I have a vague idea of how this could happen, I think the screw might be pressed against the small 'ledge' (take apart the cube and you'll see what I mean, a lot of dust builds up there), and it gets stripped that way?

I'll try using a screw with a smaller head that doesn't get caught on the ledge.

That's a good idea. The screw from my Cubetwist has a smaller head, so I'll try that once my replacement part comes. Maybe also sanding down the area around the screw would help, although seems kind of hard.

I have done roughly 1000 solves on mine, and nothing has happened to it, and this only seems to have happened to people who have done lots of solves, so I'm sure that doing a few solves on it won't do much (if any) harm to it.

What do you mean by a few solves? A few solves in a session? Or will this happen if you just solve too fast or too rough?

I dont know if this works, but i Think i found a solution. I tried glueing the screw into the core, since then my brother has 100+ solves and it hasn't loosened it self yet. Hope it helps

Same thing happened to me. Exact same. I'm buying a new one. Hope this doesn't happen again.

does that mean my qiyi square 1 is dead ?

All I did was to unscrew the whole thing, drop some superglue into the screw hole and screw the screw back in. Seems to hold up just fine, and the tensions are still adjustable.

Based on a discussion with Thomas Kaunzinger on Facebook, I replaced my rectangular endcap with a lock nut I purchased at my local hardware store. I've done maybe 200 or 300 solves, and it hasn't loosened at all, so that's a good sign

I bought the #6-32 lock nut, which seemed to be the only size they carried that fit well.

A while ago I bought a QiYi pyraminx and the core came stripped, but The Cubicle had great customer service and they sent me a new one
