Bushings: Wood vs Steel, DIY Solar Tracking Array, Tilting

How to create a pivot point on the steel pipe? Wood vs Steel? In this video I make two different types of connections that will allow the solar panels to tilt and change angle. This will allow tracking of the sun angle for different times of the year, which will increase solar output.

The first design uses a steel ring and a plastic bushing. The second type is an oak yoke. I made both types as a test. I wanted to see how long they take to make, and ultimately help me decide which one to use on my solar project. I call this a bushing, not bearing. Hopefully I'm getting the right terminology.

If you are unfamiliar with this project, then please check out my video showing a plan and model.    • DIY Tilting Solar Ground Mount, Plan,...   The solar array will be used to charge my off-grid powerwall.

Eventually this will be a single-axis tracking array. I thought about making a duel-axis, but choose not to. My site has shade on the east and west sides, so my solar window is fairly narrow. A duel-axis tracker just won't have much benefit in my yard.
