Assignment 6 – Mechanism
This mechanism was hand-cut from foamcore after being drawn on engineering graph paper. The gear train consists of pinions and a rack. By turning the small gear using the crank the large gear rotates in the opposite direction, driving the rack forwards or backwards. While the gears do mesh and work, they degrade quickly with use and now are fairly difficult to turn. It is still interesting that a mechanism can be easily prototyped using inexpensive materials.
