Alright, so I took my 3x3 apart today to sand down the pieces.
I used Jasa's or w/e website for a guide.
I did the centers, 4 edges and 4 corners, and I have put it back together, I am not even done with sanding, and I relubricated it with Petroleum Jelly, I had wiped it all off before sanding.
I sanded with my Dremel, with a course grade of sandpaper and then a fine grade, and then followed up with real sandpaper, not the one on the Dremel, like acual paper...if u get what I am saying.
And now my cube locks up all the time and is horrible, my time is worse now that it was before...
Wow, this is my life, try to do something good, turns out bad...
help? is there anything i can do?
Yes! Get a new cube.
It seems obvious that you sanded too much away. It's pretty well known that a loose cube tends to lock up a lot.
I've posted this before: sanding should only be done if you really know what you're doing, like doing a very little bit at a time.
There should be a file or a sticky or even (gasp!) a database for newcomers on what to do, what not to do.
Get a DIY cube with lube from rubiks.com, get stickers from cubesmith.com, solve the puzzle yourself with no help at least once.
After you get a new cube, break it in for a couple of weeks, wipe it clean and lube it, and not with vaseline. Rubiks silcone lube is all right with their cubes but not with others, like Ideal cubes.
I know what you mean about "try something good..." but wouldnt it help if you knew what you're doing to begin with? I don't mean that to be sarcastic. I take that kind of being bummed out seriously, it's just that doing the wrong thing, even with good intentions, is still doing the wrong thing.
