DIFFERENTIALS, TRANSMISSIONS, AND OTHER GEAR APPLICATIONS

Many discussions have taken place on LUGNET about different gear constructions. This page attempts to record and categorize them and to provide a concise and useful reference for users. The following links are mostly to posts on LUGNET (primarily from the Technic newsgroup, but also from the Robotics newsgroup), and a few are directly to other websites.

A link to a post is denoted by this symbol: and a link to a website is denoted by this symbol: .
