I apologize if this question has been asked or the answer is obvious. I am unfamiliar to the terminology so searching things up is a major difficulty.
I have two flat, long pieces of wood and I want to 'mate' their ends such that both can rotate about that point. I call it a 'rotating joint.' The two pieces of wood would be overlapping. Here is a video of what I am attempting to build:
The 'joints' can be seen in the four areas, two on each arm.
I would appreciate help determining what components I need and how they come together.
After research, what I believe I need is a bolt, a bearing/bushing and a nut. I would drill a hole, insert the bearing, insert the bolt through the bearing, and tighten with a nut.
