Step 1: What You Will Need
Aside from those, all you're going to need are;
- 2 small screws (like the kind on your door hinges)
- A small piece of 2x2
Suggested tools to make the job easier are;
- Needle-nose pliers
- Wire snips
Step 2: Prepare the Mousetrap
The 2 screws will secure the trap to the wood handle. Make sure you leave just a little overhang at the back.
Step 3: Make the Firing Mechanism
Modify the locking pin so that it's trimmed down in a way that it overlaps the the most forward hole you drilled, then bend the tip of the pin up at a 45 degree angle.
The next step, is to use the locking pin from the other trap as the trigger. Push the pin up through the bottom of the hole, then trim it flush with the top of the spring, and bend it over in a an "n" shape. This will prevent it from slipping back down through the hole.

Step 4: Add the Launching Pad
With the trap hammer relaxed, clip the bait pad with the hooks facing upward, then carefully lift the hammer, tuck the pad underneath, and relax the hammer back down onto the trap base.
Your gun is finished, and ready for testing!
