Leonardo da Vinci Catapult

Have some fun with this awesome catapult! Relive the experience of using a catapult from epic historical battles. It combines various elements from two catapults drawn by Leonardo da Vinci (Image below), although these catapults were never made into full scale. This includes the flexy arms of the above drawing and the gear/release mechanisms of the lower drawings, along with the frame and launcher. It fires relatively consistently and can be quite powerful, depending on the elastic bands used. No supports are needed.

 

This launcher can be quite powerful, so please take the necessary safety precautions!

• Assemble under adult supervision. Elastic bands under very high stress could break the model.
• Wear protective eyewear when operating the launcher in case of rebounds.
• Do not aim or fire the launcher at people, animals, or fragile objects.
• Operate outside in an open area.
• Only use the ammo supplied in this model kit.

	1.
	2.
	3.
	4.
	5. Glue the stopper into centre piece.
	6. Use glue. See orientation of elastic band hooks.
	7.
	8. Push the concave-shaped pin through the centre piece and into the launcher. It is quite tight.
	9. Slightly bend the frame to insert centre piece.

	13. Using the provided hook tool, loop the small elastic band around the clicking arm (see next).
	14.
	15. Loop the elastic band around the right arm and underneath the centre piece.
	16. Keep looping the elastic band. once the desired tension is set, hook it onto one of the hooks.   Caution: Do not over-stretch the elastic bands to a high degree. This will put too much tension on the plastic arms, which could snap under extreme tension.   To avoid this, make sure the elastic band is under a slight tension when the launcher is in its rest position. Manipulate the elastic band on the centre piece to create slack.
	17. Placing over hook.
	18. The second elastic band goes over the top of the centre piece and then underneath it (opposite to the first elastic band).    Repeat the same procedure. Hook the elastic band onto the second hook.
	19. It should look something like this.
