Shop notes

Measured across the joint between the Makita BO5041 random-orbit sander cuff and the Metabo ASR 35 mm hose, the hose (35 mm) is 11 mm larger than the port (24 mm), so the port rattles inside without gripping. A 24 mm to 35 mm step reducer closes that 11 mm step so the two hold together instead of leaking at the gap.

A 11 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.
