The Guts: Bearings, Couplers, and Gears
This chapter covers the guts of mechanisms, from gears to bearings, shafts, couplers, and more. One of the biggest problems my students have when working with motors is figuring out how to attach something to the shaft. We’ll cover this and much more as I step through the guts of mechanisms and show you how to choose and purchase components.
Project 7-1: Make your own gears
This project is posted as an excerpt on Make Magazine’s blog: How-to: Make your own gears. It also got picked up by Ponoko, Hackaday, adafruit industries, and How-to blogs. Some of the comments are great, including one from the Inkscape programmer who actually wrote the code that generates the gears!
