Does anyone have any ideas on how to hook up a 4" dust collection hose to a Delta 14" bandsaw? The factory dust port is about 1 & 1/4" and does almost no good. I have the 1 & 1/2 HP Oneida cyclone and it really needs good airflow to work properly. I have looked at poking (holesaw) a 4" hole in the cast iron frame just below the lower blade support. There is a location there that is just about big enough, but it would be right into the frame itself and I am concerned about weakening it. Any ideas would be appreciated.
