Wondering what opinion you had about punching several small holes in my table saw's zero-clearance insert to help with dust collection. Ever since using ZCI's, I've noticed more dust coming from above the plate. I do have an overhead guard with dust collection (Sharkguard), but don't use it all the time. I have a 3hp dust collector that is a short run from the saw, so I think there's good suction, but not where it's needed without the overhead guard. Also, I'm working in a basement, so I need optimized collecting.
