You could also diassemble and take only the core, screw it as tight as you can and then start unscrewing each side 1 at a time. When you're around a pennys width the cube should be loose enough to assemble. This will guarantee that the tensions are 100% equal on every single side, unlike with eyeballing the width of a penny.That's my problem
During assembly I noticed that I tensioned it too tight, so I loosened just one side. Usually I do the even tensions before assembly.
I was just generally curious because on a 3x3, it's quite easy to see which side needs more tensioning when you pull the cubies apart(I don't tension that way, but still). On 4x4 however, if one side opens up wider as the other ones, I'm never sure if I need to tension that said site or 2 opposite sides next to the one that's loose.
Either way, it's not too bad right now, and I'll probably take it apart for lubing anyway I guess, I'll re-tension it then.
On a sidenote, the screws were like new, people seem to have problems with messed up screws, I guess I got lucky.
You shouldnt worry too much about equal tensions, the tensions usually a find a way to even out with breaking in.
