Kid Crank Hand Drill
A redesign in form and
mechanics of the classic
“eggbeater” style hand drill
for use by kids ages 9+
problems noticed through
observation at a summer camp woodworking class:
pinching hazard from open gear
design very little torque from bevel gears confusing 2 handle design
design criteria:
design should be safer for kids through a closed gear system
design should provide smooth ample torque design should be simplistic through single handle placement
