BIG ball thrower (volleyball, football, basketball)


Requested Project

Wondering if anyone might want to tackle a new design for a ball thrower (we had a hair trigger go off  on one of our "tuned up" catapults and hit a teacher ... and he was well trained!)  Something with plenty of pop, but very safe...Still would need to be light weight, portable and throw a variety of balls.

Design Notes

The completed design is a "slingshot" style, with two 3 ft. lengths of rubber tubing passing around two pulleys.  Throwing distances of 25 ft for a basketball, and 30 ft for a volleyball were demonstrated.

RCRV designer is Jack Murphy, and was requested by GWAEA Ann Griffin. The project was begun Sep 15, 2004 and completed Nov 11, 2004.
