Screw Gears

Description

Screw Gears are four gears with missing teeth, mounted onto screws. Screws A and C are righthanded, B and D are lefthanded. The goals is to screw the four screw gears into the frame, such that they line up. That is, the letters ABCD are straight, and each screw is all-the-way in. The challenge is in the missing teeth. Each gear has some teeth missing, and a blocking surface instead. Teeth of neighboring gears cannot pass these blocking surfaces. To solve the pieces, one needs to turn the screw gears sometimes simultaneously, and sometimes separately. Because of the missing teeth, not all gears go down at the same speed. This means that one should enter and turn the screw gears in a particular order.
