I have the old Ridgid BS. It has the undersized (purposeful dig at ridgid and all BS makers) dustport at the front just under the table. I have a 5hp DC and it does not get all the dust, probably less that 90%. There is very little dust in the lower wheel housing and essentially zero in the upper. I know people add a port to the lower housing, but I dont see any benefit to this since I get less than a teaspoon of dust after cutting about two hundred feet of wood. Does anybody have some addition to their BS that helps get better dust collection?
