I replaced the tiny / puny dust port on mine with a 4" port. Unfortunately for you, but fortunate for me $$, Wood magazine owns the rights to it. One day, maybe they will publish it. I do still have pictures, but due to contract, I can't send them electronically:eusa_thin. When I cut out my Toys for Tots cars (120 of them), there was less than a half cup of dust in both upper and lower wheel housings. Each cut was about 6" long in a 2 X 4.
