New More Quiet Air Pump for my ET-2 arm

Cool. As I think I mentioned, the pump that my 'table came with ran the arm at about 4 or 5 psi. When I started raising the pressure the flow became excessive. I could hear the air rushing and the wind would effect the spindle at the end of travel. I had to torque the set screws as tight as I could to get the flow rate down enough that I could really increase the pressure.

Good luck!
