The Office supplies trebuchet

Step 12 Mounting the trigger

Push the end of the trigger into the layers of card where the center line intersects the support line(the side that the arm hook is on).
The other end of the trigger needs to run in a slit so that it can slide back and forth. Don't make the slit too long or else you risk the trigger being pulled out.

EDIT: See the last step for attaching the improved version.
