Bart Orlando demonstrates how exercise can be converted into constructive work using a pedal-powered drillpress which he designed and built at CCAT with the assistance of HSU engineering student - Aidan Semingson.
The chain is wrapped around a shaft-mounted free wheel sprocket. The horizontal shaft is supported on the right side by a pillow block. It is connected on the left side to a right angle drive which in turn spins a vertical shaft which is substituted for the drive shaft of the original electric motor.
