What am I doing wrong with these welds?

Alright so.. I'm making a gun kit but for some silly reason, my welds aren't working right. Here's how it works. There is a part called AnimBase, the real right arm, the real left arm, a clone of the right arm, and a clone of the left arm, and the head of the character. I need to weld the AnimBase to the Head, the real left and right arms to the AnimBase, and the Fake Arms to the real arms. I've gotten that done no problem. The problem is.. When you test in server mode, the arms will fall off. I do not know why and I'm getting frustrated as crap. Please help:
