Reciprocate Rotate
Reciprocate Rotate. Crank the handle and watch as the two pinions alternately drive the gear on the vertical shaft, sending it back and forth. Use this Essential Mechanism as a pure exercise in motion, or as the foundation for your own character‑based automata.
As usual, premium members of the site can download the project for free by adding it to the cart and checking out, thank you for your support!
The project comes as two files. One PDF includes all the parts and step‑by‑step instructions, ready for you to print and make. The second file contains parts only, and is easily editable if you’d like to add colour, adjust dimensions, or make your own variations.
Build the mechanism as it comes, or let it be the spark for something uniquely yours. Every maker adds their own twist, so see where your imagination takes you!
