Step 10: Rear axle

Picture of Rear axle

Push the pen with the string into the back eyelets. Pull the string through the eyelets so that it's between them (or slide through the gap if you had to widen them). Tie the string to the tip of the flap that will move as the trap springs. Those more ambitious might want to brace it with something between the spring and the back to make sure it doesn't snag or fray, but I didn't bother, which does mean the string gets tangled or frays every so often.

Is it posible to have a Video Tutorial because i am trying to follow these steps but they are quite hard for me and my 13 year old son. Help would be appreciated.
When you set off the trap, how do you get the string to not stop the axel from spinning?

 Larry, where do you put the string after, you haven't really given clear instructions on what to do with the string part.
