I didn't know how to make the title clear and succinct, so I sort of made it long.
I was contemplating a few ways to make my 4x4 keep it's alignment without pins. Other than gluing a corner to the core or attempting something similar to the eastsheen mechanism.
From this point on, I'm implying that the cube has had all the internal pieces smoothened.
So, we know that in the even number cubes, you can glue internals to the center piece on the core to keep X and Y axis from misaligning.
Well, If we tighten the tension on that center, it applies more force on only one side of the Z axis. That means that the internal will tend to move less on one side and more on the other side. This keeps the cube in alignment moreso than if the tensions were equal.
However, we are all aware of the shortcomings of cubes with uneven tensions. Like when we go to competitions and feel the way noobs have incorrectly set their tensions so that different layers have different tensions.
Obviously, one side of the cube will feel much tighter, and if used in BLD, the tight layer can be used to identify the orientation of the cube...
Oh my... I JUST CAME UP WITH A NEW WAY TO CHEAT IN BLD!!!
BY TIGHTENING ONLY 2 LAYERS ON A 3x3, YOU CAN BE AWARE OF THE ORIENTATION OF THE CUBE AT ALL TIMES!!!
Umm, back on topic, it also wouldn't eliminate 100% of the misalignment, I would say at most a 10% less alignment, depending on how tight that side is, and how loose the rest of the cube is.
At first, I was apprehensive, because when new ideas are presented, even if they have slight flaws, are instantly shot down.
Like when Carson proposed names, a totally innocuous proposal it was completely shot down. So, I'm just putting this idea out there, I'm not going to defend it, because I am aware of the shortcomings. If there's an offchance it helps someone, then great, if not, then at least I tried.
