This video will demonstrate the general technique, design and how to for the build of the bearing. The bearing will slide on an aluminum or steel angle (or a metal round rod if you prefer) keeping the bearing in place. First, you will need an angle, easily acquired at your local hardware store. I use an aluminum angle for the ease of drilling and tapping. I will explain tapping in more detail later. Notice the imperfect cut at the end of the angle. This is ok since the z-axis will use compression to stay rigid.
