Connect a Makita LS1219 miter saw port to a Makita 38 mm hose
How to join a Makita LS1219 miter saw port to a Makita 38 mm hose, and what stops it leaking dust.
Not a direct fit. Joining the Makita LS1219 miter saw port to a Makita 38 mm hose needs a 1-3/8 in to 38 mm step reducer.

Shop notes
Measured across the joint between the Makita LS1219 miter saw port and the Makita 38 mm hose, the hose tip (38 mm) is 3 mm larger than the port socket (35 mm), so it will not seat. A 1-3/8 in to 38 mm step reducer closes that 3 mm step so the two hold together instead of leaking at the gap.
A 3 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.
