Step 1. Prepare the tools and the materials
- A clothespin
- 4 small screws or nails
- 4 nuts for the bolts
- Two eye-bolts
- A rectangular wood
Step 2. Make the sketch and draw it onto the wood
Make the sketch of the gun and then draw it onto the wood as shown in the picture. Check the diameter of the ping-pong balls prior to making the gun. Adjust the templates for kids as the templates in this project are suitable for 20 years old man.
Step 3. Cut the templates from the wood
Place the wood on the workbench and clamp it onto the table. Start from the gun handle as it becomes the gun’s hardest part. Don’t need to be really precise when cutting the lines of the handle. Leave some wood to finish it later on for filing or sanding. After all pieces are cut, sand all parts to make them all smooth and nice. Spend more time to sand the curved edge of the gun to make it perfectly shaped.
Step 4. Build the gun
Joint the rectangular wood onto the gun. First, make the rectangular piece with 15cm length. Sand the piece to make it smooth. Find the center of the wood and drill a hole as to attach it into the gun. Drill a hole on each end of the wood as the place to attach each eye bolt. Leave 0.5cm from the edge. Insert the eye bolt and secure the joint using a not on both sides (top and bottom). The eyes will be used to attach the elastic to fire the balls.
Step 5. Drill the holes for ammunition
Use the holesaw to drill the hole. Attach the holesaw onto the gun and drill the holes. To make the holes drilled correctly, make some pre-drill holes using the nails. Clamp the wood down to keep it in place while drilling.
Step 6. Assemble the pieces altogether
Attach the rectangular wood onto the gun using 2 small screws and nails. Place the rectangular wood perfectly at the center of the gun. Add glue at the bottom of the gun for additional support. After it is ready, add the clothespin onto the gun as shown in the picture. Attach the string into the clothespin and secure the clothespin with the spring using small nails. Load the gun with ping pong balls and try to shoot the balls to see if it works well.
