Hi, my GuHong will often loosen itself, and an entire side will end up falling off. Even happened when I was about to get really good solves. Has anybody else had this problem? And if so, what should I do?
I think if you use an A-I core then you dont need new screws and springs and its also the best core for it, so no C4U or A5 cores. I may be wrong though...
You could take a very small piece of paper and set it between the screw and the core. I think you'll still have to keep tightening it eventually though, just won't be as often.
this happens with almost every screw/spring/core i've used. its just a fault of the cube. the guhong pom supposedly addressed this fault. usually it is just one arm of the core that unscrews and i found its typically not the U face like i would figure it would be. its typically a side face every time.
I had this with one of my Guhongs. With counterclockwise moves, the screw would move along with the centerpiece, because the head of the screw was a bit to large. Not sure if this is the same on your cube. Anyway, I solved it by widening the circular gap, right where the head of the screw was touching the centerpiece. Works fine for me now.
