Every gear pair trades speed for torque. Chain your stages below to see what the mechanism actually does.
Drawn to scale (module 0.8) · slowed so you can follow it: really 312 RPM in, 104 RPM outOutput turns the opposite way to the motor — 1 mesh, and each one flips it.
Gear stages
Add a stage for every gear, sprocket, or pulley pair in the path from the motor to the mechanism.

Before friction. Real mechanisms lose roughly 5–10% per stage, so treat this as a ceiling.
Rule of thumb
Speed and torque trade directly. If you double the reduction you halve the speed and roughly double the torque — you never get both.
