Shop notes

Measured across the joint between the Festool OF 1010 router port and the Fein Turbo 35 mm hose, the hose (35 mm) is 8 mm larger than the port (27 mm), so the port rattles inside without gripping. A 27 mm to 35 mm step reducer closes that 8 mm step so the two hold together instead of leaking at the gap.

A 8 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.
