Nice phaidinyak! Pretty smart setup!
I made a similar setup to AncientCowboy’s. One difference is I have an additional swivel joint in the ductwork was well. The duct swivel joint is a 3D printed creation, and the swivel joint for the 2x4 boom rotates on a weldment using a 1" pin with HDPE bushings. It has a spring return, so it is always biased to one side. My ceiling is 7 1/2’ so the duct hanging below the boom is low enough that the cable carrier of the CNC would hit.
I was very concerned before I bought my machine that I could have a good dust collection system with my super low ceiling that didn’t require babysitting. This thing works beautifully.
