Shop notes
Measured across the joint between the Biscuit / plate joiner 35 mm port and the 2-1/2 in Craftsman locking hose, the hose (57 mm) is 22 mm larger than the port (35 mm), so the port rattles inside without gripping. A 35 mm to 2-1/2 in step reducer closes that 22 mm step so the two hold together instead of leaking at the gap.
A 22 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.
