Today my son broke his Buzz Lightyear's arm at the elbow joint. Now I'm not sure if all the joints are similar, but I suspect that they are, and could very likely be fixed the same way should they break.
Regardless, we have a toy with a broken limb, which means it's not being played with, and as we all know a happy toy is one that is being played with. So let's get to work!
Step 1: Preprare for surgery
The screw that is located in the shoulder is easiest removed if you rotate the shoulder joint so that the screw is facing downward into what would be the armpit.
Step 2: Remove elbow joint
Once you have the elbow joint removed, open up the forearm and remove the small gray plastic piece that is contained within. Set aside the forearm pieces,and the hand. We're going to focus on the small gray piece that you just removed and the elbow joint.
