I used clippers to tear through the hull of the excavator and it left a pretty wicked gash. The socket the boom fits into was full of wires and worky parts which ran the toy. As previously stated I gutted the monster and then reformed the socket with more thin card and the rest of the tp roll. This is the base layer for the detail I plan to add to make the excavator look more 'Imperial'.
The last photos here shows the scale of this thing pretty well. It's big.
