Abiline, TX (Spring 2006) -- During the '01-'02 year, the SPS group wanted to design and build a catapult. Tim Rackler was the drving force behind the project. We required them to start with a small-scale kit, with the plan to expand it later. They attatched it to a stool, cocked it, and shot it. It shot about 40 yards, depending on what we shot. The big version never materialized.

Although this catapult never became a full-scale siege weapon, the department used the model to discuss some of the physics principles involved to those bright young incoming students over the next couple of years. Then during the Fall of '05, a very different SPS group composed of students who were freshmen in 2002, decided that it was time to build the big one. Money was raised from MSG (McMurry Student Government) and the supplies were (mostly) purchased. The Physics Workshop (room 137) was cleaned and the project begun! ... This is their saga...
