Well, the hinges tend to get a bit weak after alot of use. I was just wondering if any of you have developed a way to tighten it, without having to order a new one from Lego.

You can disassemble the parts and spray them with a clear thin protective coat like you would use to prevent smudges to pencil art.

This is the reason LEGO switched to the click hinge.

If you get desperate though dip the part into a jar of peant butter and wipe off the excess. It should work. ;)
