Greetings. I've been doing occasional woodworking for a long time and have most of the basic power tools. I suspect that I still belong in the "beginner" category, however. Had more than one bout with bronchitis after using a router, so now that I am retired and have more time for woodworking, I've become serious about dust collection and especially wearing a respirator. Got the Harbor Freight DC and trying to decide how I want to build a Thein baffle.
