Dis-disassembly

If you like to fiddle with the stuff you own, you know that it's harder to put things back together than it is to take them apart. You end up with extra screws. You forget which part faced which way. It's tricky. My suggestion is simple: set up a video camera and record yourself as you take the thing apart. Then if you have any trouble, you can go back and see the way things were before you screwed them up.
