Shop notes

Found on: DeWalt DWE6421, DWE6423 and similar 5 in random-orbit sanders.

The sander ships with a stepped plastic adapter with three concentric tubes at roughly 26, 32 and 35 mm. A Bosch 35 mm hose slips off the smallest tube but grips inside the mid tube, which is the documented way to hook a DeWalt sander to a 35 mm extractor hose.
