Shop notes
Measured across the joint between the Oneida Dust Deputy 2-1/2 in inlet and the Festool D36 antistatic hose, the port socket (57 mm) is 13 mm larger than the hose tip (44 mm), so the hose tip rattles inside without gripping. A 2-1/2 in to 36 mm step reducer closes that 13 mm step so the two hold together instead of leaking at the gap.
A 13 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.
