I have a DynaCNC table with a Porter Cable variable speed router. I need to cut down on the dust in my garage and want to purchase or make a vacuum attachemt for the router head. Anyone know where I can buy one or have recommentations on how to make one? I can't seem to find anywhere to purchase the "Brush" material to put around a mounting plate to attach to the bottom of the router. Any suggestions would be appreciated. I tried to search the forums but didn't find any information on this subject.
