I am fabricating an item to help support a human chin on something like a microphone stand. I have parts that I want to purchase or slightly change. The main part I need is in the first three pictures. It's a plastic component threaded on one half and has a 1/2" smooth section on the other half. The last picture is the chin cup that slides into the smooth part.
I don't know what to call the part in the first three photos so I cannot locate where to purchase it. It reminds me of a smooth bore bushings. I could also fabricate this out of pipe with a guaranteed inside diameter of 1/2"......it would need to be weldable pipe though.
