Sophomore Josiah Sanchez created a functional trebuchet during his construction class. He started the project in honor of construction teacher Jonathan Phillips’ last year at the high school.

“Josiah is self motivated and works really well,” Phillips said. “He did a pretty good job.”

Sanchez researched catapult designs with his father where they discovered that trebuchets are the most efficient form. 

“The research didn’t really help that much,” Sanchez said. “I only made progress with trial and error and the help of my classmates and dad.”

The catapult is designed entirely out of wood. Sanchez had to add wheels to the trebuchet for easy movement.

“The hardest part is probably moving it,” Sanchez said. “Every time we try to move it, we need six or more people.”

It took an estimate of three months to build the frame. Another month was required to make the catapult functional.

“My parents have gone crazy about the trebuchet,” Sanchez said. “Coach Philips has also been incredibly supportive.”

There is a wide variety of factors involved in the creation of the trebuchet, including dimensions and physics. At its current dimensions and arm length, it throws about 37-40 yards.

“This was my pride and joy,” Sanchez said. “I genuinely enjoyed the creation process and I’m very happy with the finished product.”

Sanchez uses fruit to demonstrate the trebuchet. He plans to continue upgrading his design in the future.

“My dad challenged me to create this,” Sanchez said. “I’m excited to keep rising up above his expectations.”
