Recently started working on a massive kitbash, my ptitvite's inspired devastator. I've had lots of luck and success as far as my joints and articulation. However, when finishing the upper body, the weight of an arm is too much for the shoulder's join, the mere weight of the upper+lower arm, make is slowly drop. Anyoen know of a method or trick to stregnthen the ball joint? the ball is already an EXTREMELY tight fit in the socket.
