Now I'm testing a simple animation, which providing successful will allow me to do a few things I'm intending on doing.

The premise of the animation is simple. Theres two objects: one is larger and has a pole, the other is smaller and slots through the hole (No.1 Attachment) the idea is to make it the entire thing move back, the smaller piece hit the larger one as it rotates backwards. Basically, like the recoil of a gun. This is the problem I've been getting: (No.2 & No.3 Attachments)

despite havign them rotated at the same time, it still goes wonky and off.

Can someone please help me and tell me what I'm doing wrong?

Its 2009 XP 32 bit btw
