I have a PM66 and the dust collection is not that good. I do not have a overarm collector thing, but I do have dust collection hooked to the port on the back of it. I have great suction from my dust collector, but it is pulling the air from all the wrong places, like where the table hooks to the cabinet and where the adjustment handles come out of the cabinet. Since I use a zero clearance insert, no air is getting through near the blade. Other then buying a overhead blade guard thing (eventually I will), what else can I do? What are all of you doing with you saws and dust collection?
