Shop notes
Measured across the joint between the Kreg 720 Pro pocket-hole jig port and the 1-7/8 in shop-vac hose, the hose tip (48 mm) is 21 mm larger than the port socket (27 mm), so it will not seat. A takes a 27 mm hose tip to 1-7/8 in step reducer closes that 21 mm step so the two hold together instead of leaking at the gap.
A 21 mm mismatch feels close enough to force, and it will hold for a minute before it works loose under airflow. Fit the step ring rather than trusting friction on a gap this size.
