Shop notes
Measured across the joint between the DeWalt miter saw dust elbow (1-1/2 in outer) and the Festool D27 antistatic hose, the port (38 mm) is 15 mm larger than the hose (23 mm), so it will not seat. A 1-1/2 in to 27 mm step reducer closes that 15 mm step so the two hold together instead of leaking at the gap.
A 15 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.
