is there any way to tighten a ball joint thats loose? i really played with my g2 cyberjets and they are very loose in the legs and arms ... save for the canon arm, which is still remarkably tight on all of them. interesting yes? but yeah how do i tighten a loose ball joint?
Nail Polish, super glue, any clear coating material. If the ball joints will separate, pop them apart, coat the ball, let it dry, pop them back together. May take more than one application if it's REALLY loose.
A bit of tissue paper in the ball joint will do the job very nicely, and it doesn't involve any chemicals or other kinds of permanent alteration to the material. Sounds a bit cheap and nasty but give it a try, it really does work brilliantly.
Future Floor is my friend for these situations. I love Future so much that I cannot remember a single Transformers figure I've gotten in the past year or two that did not get at least a touch of Future in their joints.
