In order for me to successfully replicate the ballista from the photo, I wanted to make a smaller model of the ballista. I first planned my time accordingly across the few classes I have, for the first class, I was planning on making the shaft of the ballista, which I finished in time.  For the next class, I wanted to make the capitulo, frame or head, of the ballista. After that, I will make the arms and the launching mechanism of the ballista. The fourth class was time to do the rubber band that will store the energy of the ballista. The fifth class was for the winch lever of the model, and the last class is for the stand.

My success criteria are:

  1. The ballista needs to be functional
  2. The shooting mechanism should be the exact same as the reference picture
  3. The ballista is small enough to be easily moved around in the room.
