I recently bought a used 3100 Ck and plan to run 8" duct from it reducing that to 6" that will go to a single ceiling drop in one bay. That will be further reduced to 4" as needed for the particular tool. All of my heavier tools including a 1400lb. planer are on Portamate 3500 and 3550 mobile bases so moving them to the drop won't be an issue.

Looking for advice from those who have done something similar with their JDS 3100 ck or equivalent.

Thank you
Ron
