Recent Updates
Added a Reverse button to reverse the animation
Added a reverse button to reverse the animation plays clockwise or counterclockwise.
2026-04-09Added a Reverse Engineering section
Added a Reverse Engineering section to help users reverse engineer gears. Reverse Engineering gear geometry is available here.
2026-04-03Added a How to Use section
Added a How to Use section to help users understand how to use the app. How to Use is available here.
2026-03-28Base Pitch Table Lookup and Module to Diametral Pitch Converter
Added a base pitch table lookup tool to help narrow down the number of teeth to span (k) by pressure angle to then verify the base pitch. Also added a module to diametral pitch converter tool to help convert between module and diametral pitch.
2026-03-18Aligning gears in a geartrain
Starting capacilities are external spur gears, and aligning the gears in a geartrain in a custom x,y grid system.
