Hi everyone, I purchased a hybrid Grizzly table saw a few months ago. The manual stated that the dust collector has a 4 inch port opening. Well, I purchased an adapter to fit the saw port opening on one end and then connect to my craftsman wet/dry vacuum hose. The wet/dry hose measured with verniers is 2.190. The adapter that I purchased is 4x2 and a quarter inches. However, the adapter will not fit the saw port opening or the vacuum hose. Scratching my head over this. But, I am slightly retarded and have no mechanical abilities. I don't know if I worded this correctly so that you can understand what I'm talking about. Best wishes and thoughts during these difficult times. Thanks.
