You know the type of connection that holds your cars rear view mirror on - where it's tight enough that it won't move, but loose enough that you can move it by hand.
Does anyone know a source for buying just the two pieces of such a joint? I imagine it would be tricky to get it just right, and stay right over time.
I'm working in 6061 AL, so preferably the joint would be made of AL too.
Also, if someone knows how to machine such a joint, I'm all ears
