This is now how I am attaching hose (it swivels). Using 2 1/4 inch shop vac hose (standard) with the adaptor
that hooks two hoses together. I added a piece of aluminum to bottom side. On a 45 min. test project,
the dust was minimal (middle picture) and something I can live with. The aluminum angles at about a 45
degree and is about an 1/8 above board while being cut.
