See every movement travel through the machine
Switch it on and watch motion pass through the exposed gears, belts, shafts and flywheels before reaching the four rotating sails.
Because the transmission remains visible, every rotation reveals how the complete mechanism works as one connected system.
A full-scale mechanical challenge
Build the windmill through approximately eight hours of focused assembly, fastening the gears, linkages, transmission components and wooden base into a working kinetic model.
The illustrated manual and essential assembly tools are included, with no glue or soldering required.
Built to keep moving after the build is done
Standing 11.81 inches tall and weighing approximately 2.24 pounds, the completed windmill has the scale and stability of a true mechanical centerpiece.
USB power keeps the mechanism in motion on a desk, shelf or workshop display without relying on natural wind.
Difficulty Advanced · Best for experienced builders
Estimated build time 8 hours
Tools Screwdriver and needle-nose pliers included
